Within industry I feel there is a very bad trend at the moment, many firms are trying to save money in the wrong ways. The main concern I have is with the plumbing and gas industry and their blatant disregard for Electrical safety. There any many companies that put pressure on their installers to wire the heating systems.

News flash - they are not qualified and indeed nowhere near competent to do so, unless they have received adequate training. It might save money in the short term but imagine the lawsuit when someone’s house is on fire or someone dies from an earth fault because of inadequate Earthing.

As an Electrician I’m fed up of being approached by these companies asking if I could sign off their work. Quite frankly a majority of the time their work is like that of a child and nowhere near the standards required for me or any other sane Electrician to put their name to. I have worked for many heating firms over the years and the only way to ensure safety and quality of work is to have a competent Electrician to do the wiring, in my experience one Electrician can easily wire three to five heating systems a day.

This is where I get the title “each to their own”. I am not expected to connect up a gas pipe and I would never attempt it! But Heating installers are encouraged to do Electrical work and in my eyes its madness unless they have received adequate training.

Not all electrical work requires a trained professional. Minor tasks such as replacing a light switch can be performed without having to notify your Local Authority Building Control Department, however they still must be done to current Building and Electrical regulation standard.

While there are a wide variety of different types of light switch you might find in the home (including pull-cord switches, narrow architrave switches and rotary dimmers), here is a guide to the most basic of them – the one-way and two-way switch. The difference between them is that two-way switches are used where there is more than one switch connected to the same light (e.g. at the top and bottom of the stairs).

Safety first

Before you start ANY sort of electrical work make sure the power is switched off at the main consumer unit OR switch off the relevant circuit breaker and lock it if you can. Then make sure that the circuit is indeed dead using a voltage tester/meter. Also take note that since 2006 the core colours inside electrical cables have changed. In the new two-core-and-earth cable, the live or phase core is insulated in a brown sheath rather than red. The neutral core is now blue as opposed to black.

What you will need:

  • Voltage tester/meter
  • Side cutters Screwdrivers
  • Green/yellow earth sleeving
  • Suitable replacement plateswitch (1 or 2-way)
  • Screws
  • Brown PVC electrical tape or sleeving

For one-way switches:

Step 1: Isolate the circuit and then confirm that the power is off using your voltage tester. Unscrew the switch faceplate and pull it forward, revealing the connections behind. These terminals will usually be marked something like L1, L2 and COM.

Step 2: Draw a diagram so that you remember which colour and number of wires were attached to each terminal. Then release the terminal screws and pull the cores from them. If the earth core is properly insulated in green/yellow sleeving and connected to the mounting box, leave this attached.

Step 3: Connect these cores to the correct terminals of the new switch, using your diagram as a reference. Tighten the screws and check they are clamping the cable cores firmly by gently tugging the wires.

Step 4: If there isn’t one already, fit a length of brown sleeving over the blue core to indicate that it is a switched live.

Step 5: If it’s not already fitted, put some green/yellow sleeving over the bare earth core of the incoming cable and connect it to the earthing terminal of the mounting box. If you’re using a metal switch, be sure to earth the switch faceplate as well.

Step 6: Double check that each connection is secure, then push the cable back into the mounting box and fit the faceplate.

 

For two-way switches:

While this is similar to a one-way switch there will normally be three cores to the cables – coloured brown (formally red), black (yellow) and grey (blue). Again these terminals will be labelled something like L1-3 and COM.

Step 1: Isolate the circuit and make sure the power is off with your voltage tester.

Step 2: Remove the faceplate from the existing switch and disconnect the cable cores.

Step 3: Note which colour goes to which terminal (write it down if you think you’ll forget!) and then transfer them to the corresponding terminals on the new switch.

 

While this is simply a brief guide to some of the electrical work you can do yourself around the home, more technical electrical work will require you to have a Part P qualification if you wish to carry it out yourself. If you are interested in learning about more work you can do or achieving Part P qualification then the best way is to learn from one of Access Training’s comprehensive electrical training courses. Offering professional qualifications to both aspiring and existing electricians as well as DIY courses, there truly is something for everyone regardless of age, gender, background or experience.

Although Part P Building regulations require a qualification to undertake extensive electrical work in your own home, minor tasks such as replacing damaged sockets or light switches can be done without having to notify your Local Building Authority Control Department. In this post we'll take you through a few simple steps to replace a plug socket or alternatively change a single one into a double.

Safety first

Before you start ANY sort of electrical work make sure the power is switched off at the main consumer unit or switch of the relevant circuit breaker and lock it if you can. Then make sure that the circuit is indeed dead using a socket tester. Make sure to also have protective gloves and safety goggles on you at all times.

Also take note that since 2006 the core colours inside electrical cables have changed. In new two-core-and-earth cables, the live/phase core is insulated in a brown sheath as opposed to a red one and the neatural core is now blue rather than black. If you are connecting old and new cables together, take extra care to make sure that the cores are attached by their corresponding colours.

What you will need:

  • Socket tester & socket template
  • Screwdriver
  • Pipe and cable detector
  • Drill
  • Socket faceplate or new double socket
  • Wall plugs and screws
  • Mounting box
  • Green/Yellow pvc sleeving
To change a damaged socket:
Step 1: Confirm you have switched off the main power using your socket tester. Once sure unscrew the socket faceplate and pull it away from the wall. Keep the screws just in case the new ones don't fit.
Step 2: Loosen the terminal screws and release the cable cores. Should the insulation be heat damaged, cut back the cores and strip the ends. If the earth core is bare, cover it with the green/yellow sleeving.
Step 3: Connect the brown (or red) core(s) to the live terminal of the faceplate, the blue (black) ones to the neutral terminal and the earth core to the earth terminal. Tighten the screws fully and fit the new faceplate. When you have turned the power back on, use the socket tester again to check it is wired correctly

To change a single flush socket to a double:
Increasing the number of sockets in a room isn't as difficult as it might sound if you follow these simple steps...
Step 1: Isolate the circuit and then use the socket tester to make sure that it is dead. Unscrew the faceplate and disconnect the cables from the single socket mounting box.
Step 2: Knock out the middle section in the double box and pass the cables through. Mark where the screw holes are on the wall using a pencil, remove the box and drill.
Step 3: Screw the new box in place and connect the cables to the terminals. Fit the new faceplate and then test using the socket tester again once power has been restored.

Hopefully after reading this you'll feel confident enough to do these tasks yourself without having to pay for a professional electrician! However if you're interested in learning more about what electrical tasks you can perform at home with the right training, or alternatively hoping to gain qualifications to become an electrician - look no further than Access Training's range of bespoke electrical courses. From Part P to PAT Testing and wiring regulations to DIY, we offer something for everyone regardless of age, background or experience.

The 1st class cricketing countries are about to start their annual campaigns. Amatuer cricket clubs are preparing for the up and coming season - all hoping for a summer of sunshine and warmth. Families are planning to tidy up the garden, trim the hedges, cut the grass, have barbeques and generally have lots of fun in their gardens. The patio lights are about to be brought back to life - but are they safe?

The lights have probably been exposed to the elements all winter long - drenched by rain, buried in snow and buffeted about by strong winds. The damage they have sufffered may not be immediately evident. Even if you throw the switch and the lights come on they may not be safe! The internal damage may not be apparent until some some poor unfortunate soul touches them - FLASH BANG one of your loved ones is now lying on the floor having received an electric shock (it could even be you!). The lawn mower and hedge cutters have also been stored away in the cold damp shed. Have they suffered any adverse effects from months of inactivity? Do you want to find out the hard way?

It would be a good idea to have the lights (and any other electrical equipment you intend to use in the garden) checkeds out by a competent electrician. Just to make sure it is safe and in good working condition. The small cost involved could be the difference between having a "glorious" summer and a summer never to be forgotten!

Asking this raises a number of other questions. The plumber may be capable of connecting cables to the shower but does he know how to check that the existing cable can take the load current of the new shower? Does he know how to carry out all the required electrical tests that are required when installing new electrical equipment? Does he have access to the required test equipment to allow him to perform the tests (this equipment is expensives - in the region of £600+, and usually only carried by qualified electricians)? If he has access, is it the right equipment? Is it manufactured to the revelent BS or EN standards? Has it been well maintained and regularly calibrated? Does he have and can correctly fill out the correct electrical test certificate for the job? Has he informed you that you will need to notify the local building authority control (any electrical installation work that has been carried out in a room containing a bath or shower has to be pre-notified as a requirement of Part P). Oh yes I nearly forgot - there is also a charge payable to the Building Control Authority to notify works under Part P!

Are you starting to wonder if the plumber is the man for the job? If you have any doubt whatsoever, no matter how small - get a "proper" electrician to do the work. One who has undergone training and experience in doing the work. Engaging an electrician who is a member of a recognised 'Competent Person Scheme' will save you the cost and hassle of dealing with the Building Control Authority.

Have you made your mind up yet?

The question most electricians are asking in this day and age is which CPS (Competent Person Scheme) to join - there seems to be quite a choice out there. Does it matter which one we choose? We could go with the well known few or alternatively try one of the other scheme operators. What are we getting for our money?

Well let's be clear about one thing - they are all equal! Each scheme has to be approved by the Department for Communuties and Local Government (DCLG) and all have to meet the same criteria. No scheme can therefore be discriminated against and one scheme should not be a preference over another in any contractual specification. To do so would be against the law.

So in reality it doesn't matter which scheme you choose, it's down to personal choice. Some are better than others if you want to move into the renewables sector. Most are upfront and explain their charges clearly. Some will even give you stickers for your vehicle; others don't - you have to pay for them! Some offer a workmanship guarantee as part of your membership, with others you have to purchase this separately.

So in my humble opinion, shop around and go for the scheme that offers your company the best service for you. Every scheme has to assess you to ensure you are working to a competent level; that is the important factor in all this, not which sticker you put on your van.

Part P Changes

In 2013, the Government made important changes to Part P of the Building Regulations. These are the regulations that ensure that all fixed electrical installations in domestic dwellings are suitably designed, installed, inspected and tested to provide reasonable protection against becoming a source or fire or a cause of injury to persons.

These changes to the Part P of the Building Regulations consisted of two principel modifications, the first of which reduces the range of electrical installation work that needs to be notified. Previously, electrical work undertaken in kitchens (such as adding a new socket) or gardens (installing security lights) were among the work you'd need to be Part P qualified to perform without having to notify an inspector. However now these tasks will no longer be notifiable unless a new circuit is required.

There are three main areas where electrical work will still be notifiable due to Part P of the Building Regulations, and these are:

  • Any work involving the installation of a new circuit
  • The replacement of any consumer unit
  • Any addition or alteration to existing circuits in a special location
In this instance, "special location" can mean two things, the first of which is any room containing a swimming pool or sauna heater. Secondly, it is any room containing a bath or shower, where the space surrounding a bath tap or shower head extends vertically from the finished floor level to a height of 2.25m, or 2.25m from where the shower head is attached. This can also apply horizontally, where the bathtub or shower tray has a distance of 0.6m. Alternatively, where there is no bath tub or shower tray from the centre point of the shower head where it is attached to the wall or ceiling to a distance of 1.2m.
 
The second part of these changes to the Part P of the building regulations relates to the use of a registered third party to certify notifiable work. Previously, any electrician undertaking work that fell under Part P not registered with a competent persons' scheme was required to notify their local authority's building control. They would then send out an independent inspector who would determine if the work was acceptable.
 
However, these changes mean that electricians not registered with a competent persons' scheme have to get their work signed off by a registered third party. For more information, visit the official Government Part P document.
 
Are you looking to become Part P qualified? Not only will this enable you to register with a competent persons' scheme and allow you to self-certify your own work (saving you hundreds of pounds), but could also potentially provide you with a whole new area of work when the third party approval system is finalised. Here at Access Training we offer a wide range of electricial courses, including specific Part P Training. If you would like to find out more, give us a call on 0800 345 7492.

This is a question posed by many a householder, however of the reality is that it might not need to be changed. If the fuse board is damaged and there's a chance that people could touch "live" parts (risking an electric shock), then it does need to be changed.

The old fuse board will not meet the requirements of the BS7671 Wiring Regulations 17th Edition Ammendment 1 (2011). The fact that the installation does not meet the requirements doesn't mean it is illegal or indeed unsafe, however the new requirements are intended to make the installation "more" safe by reducing the chances of getting an electric shock.

In order for your domestic installation to meet the requirements of the "Regs" it must also meet the new RCD (Residual Current Device) requirements. RCDs cannot be fitted in older style fuse boards so if your installation needs to be brought up to date and made safer a new consumer unit will be needed.

There are numerous areas where RCDs are required, which should be rated at 30mA. These include;

  • Any cable buried in a wall or partition at a depth of less than 50mm from the surface requires protecting by an RCD unless it is protected by earthed metalwork such as conduit or trunking.
  • Any cable passing through a wall or partition that contains metal parts other than screws or nails.
  • Any cable that is installed outside the 'cable safe zones' needs protecting with both earthed metalwork and an RCD.
  • Every socket outlet rated 20A or less that is used by "ordinary persons" (i.e. home owners) intended for general use, require RCD protection.
  • Mobile equipment used outdoors rated up to 32A.
  • All circuits supplying power to a room that contains a bath or shower are required to be RCD protected.
If you ask an electrician to install a new socket and you do not have RCD protection, then this new work will need to meet the requirements. This could mean that your fuse board will need to be replaced so that the RCDs can be installed! This simple and relatively cheap job has now become much more expensive, but the end result is that your electrical installation is much safer.

Should you be planning to do this (or any other electrical task) yourself, have you considered taking one of Access Training's bespoke electrician courses? Whether you're looking to gain new DIY skills to help you around the home or professional qualifications in order to become an electrician, we can help you.
