Terminate SWA in Wiska or straight to Garage CU

[doobereewotsit]

Hello all,

I wanted to know the best approach of connecting to a Garage CU.

Currently planning a small wiring project that i want to do in a few months time, when cash and time allows.
My plan is to do the work myself and go through the proper channels of notifying the work to the local council so i am building a plan of what i am doing and what kit to buy.

The plan is to run an SWA from the house(own supply) to the garage/ workshop.
My first question is with regards to the termination of the SWA where it meets the garage/ workshop.
The SWA will be the supply to a garage Consumer unit but my question is do i terminate the SWA in a Wiska box on the outside and then run a TE from the junction box(wiska) to the supply on the CU, which will be on the opposite side of the wall? or do I terminate the SWA on the Wiska box but strip the cable such that i feed the cable direct through the garage wall and into the CU?

I ask as trying to feed the chunky SWA through the wall and direct to the CU will be untidy and id like the supply to feed the CU from direct from the outside into the back of the CU.

I hope i am making sense.

Thanks all

John

That doesn't mean they are doing it correctly though. Might as well not bother.

The sad reality is I have no guarantee anyone will do anything correctly, I just have a piece of paper that says it’s his fault not mine. Should anything go wrong.

Still don't know what the earthing arrangement is...
OP, please see questions in post '#18 above.

A lot tidier would be under the shed and up through the floor. Why have a gland and point of termination outside when it can be inside ?

Fair point from a why have an external termination point of view.

Where you seeing the post number?

Anyway.
Earth would be coming from house in SWA. connection at earth terminal in CU.
Connect SWA to earth terminal and the first socket on radial.
Each socket on radial earthed as metal being used.

Post number is right at the bottom of the post next to where it says +Quote in grey.
Spoon is asking what is the earthing arrangement for the installation, how does your supply derive its earth path and by which connection method.

Ah it’s not there on portrait view on my mobile. Is on landscape (tilting phone).

Technically no where as this is all theory.

You mean the main supply to the property? Looks like the earth connects to the main SWA coming into the property. Assuming that’s what it is. There’s definitely an earth block there.
So depends if I take supply from main supply of house or socket ring.

I think that you need to get an electrician in.

Thanks for that. Generic but valid response.

Of course getting an electrician in would solve everything. But that’s not what i am asking.

As frustrating as it is sometimes to posters on here, you have no control over or rights to the answers you get to your questions. If you are not getting the answers you expect or want then you must want a particular answer, which means you already know the answer.

Your question was, "I wanted to know the best approach of connecting to a Garage CU."

Having weighed up all your plans and responses to questions, I too feel Vortigern's response is the route that best answers your question.
A local electrician may be open to you helping by installing the first fix to their design, which may be a good compromise.

I wasn’t unhappy with any response.

My question was specifically relating to the connection to the CU from outside.
Others asked more questions of me that don’t affect whether I go through the floor or through an external box. In answering those questions I expose my lack of knowledge and terminology.
And which point the thread goes off topic.

Terminate to isolator box/switch then cable to CSU phone insurers and make sure the shed is covered.

For what it’s worth. I have had a sparks round about this job but as I say it’s not what I was asking.
The forum suggested I’d get help with questions, which I have, so thank you all for your responses. Specifically those that answered my question.

All my questions are relevant, as they affect the installation.
If you do not know the answers to them then you can either find out the answers or get someone in who can.

You can get a retrospective certificate by your LBC, it’s called a Regularisation Certificate: my LBC charges £600plus vat for that.

It's not that simple with electrics and people of the public requesting info. We have to look at all the factors when giving out info. You should be able to understand this.
