Adding sockets to a radial circuit in different directions

[finlamit]

Hi.

I have a radial circuit supplying electricity to the garage (part of the house). It's on a 20amp breaker, uses 2.5mm cable. It currently only supplies a single socket. Before anyone asks, its 100% a radial circuit. 6 months ago I had an electrician install a new consumer unit, and the testing/certificate that followed states this.

There is a single socket on the circuit. Annoyingly, the socket is at the back of the garage and right in the middle of the wall.

What I would like to do is keep this socket. Then... come out of the socket on the left, and put a socket on the left wall, and out of the right and put a socket on the right wall. I cant continue the cable round in a single direction as the garage door and other things are is in the way. Coming off in both directions from this socket it the only option.

Would this be ok? An alternative I had was to come out of the the top of the socket into a junction box (30A), then the two cables come out of this... best described as a T junction.

In case anyone wondered, there will not be any high load appliances used. One will supply the chargers for my tool batteries, the other will be Christmas lights!

Thanks in advance.

There's no problem with connecting a circuit like that.

Thanks.

Another thing to add is that I am not a qualified electrician. Would I legal be allowed to do this myself. Would it be the same as spurring off a ring circuit (which I am allowed to do)?

There is no legal reason to stop you doing this work yourself, as long as you are competent, but it still needs a minor works certificate to be completed, along with the testing to get the results to enter on that certificate.
Junction boxes are to be avoided if possible, and you should be able to connect a total of three sets of 2.5mm2 wires to a good quality 13A socket, especially a double.

As long as you are not in a zone in a bathroom or adding a whole new circuit you are alright in England. You can download part p of the building regs for free. You still need to comply with regulations regardless. You probably won't be able to double up the cores with three in one terminal and you need to make sure it's gripping them well.

Let's not confuse the two questions of legally being able to do the work, and the requirement (or not) to notify the work.

Would I legal be allowed to do this myself. Would it be the same as spurring off a ring circuit (which I am allowed to do)?

“No person shall be engaged in any work activity where technical knowledge or experience is necessary to prevent danger, or where appropriate, injury, unless he/she possesses such knowledge or experience, or is under such a degree of supervision as may be appropriate having regard to the nature of the work.”
(Electricity at Work Regulations 1989 (EAWR) – Regulation 16)

If you meet the bit in bold then it's legal for you to do the work.
As @brianmoooore said all electrical work should be tested and documented and if you're not providing a new circuit the Minor Works Certificate can be used instead of the more complex Electrical Installation Certificate.

The other factor mentioned by @Aaron b is notification; there is some work that the local authority building control people need to be told about, and as he said that is generally bath/shower-room work, a new circuit, or replacing a consumer unit. That clearly doesn't apply to this instance.

It's OK saying that, but if he electcutes him self or somebody who picks the phone then.

If he electrocutes himself, or anyone else, then he's clearly not competent.

If he's dead, he won't have to prove he's competent....!

On his head stone it will say he tried.
