Wiring to Garage under floorboards SWA Required?

[Martyn Campbell]

Hi,

My Garage is attached to my house and currently there is a standard 3 core cable running from my consumer in there. I have just had my consumer upgraded/replaced and starting renovations on the bedroom directly next to the garage so would like to replace the cable as well. As the cable does not go outside as it is under the floorboards of the bedroom then through the wall into the garage do I require SWA?

Many Thanks in advance

All my work is checked and certified by a qualified electrician on completion.

you don't need SWA as long as no part of the cable is buried < 50mm deep in wall/s or under floors. if you want to use T/E bear in mind the size of the cpc being smaller than the live conductors.

Many Thanks for your response, unfortunately I do not know what you mean by CPC being smaller than the live conductors :-(

If it is any use I am powering LED Striplights, Freezer & Tumble dryer

This line indicates that you really ought to get an electrician in to do this work. No shame in knowing your limits.

Probably best to ask the electrician who is going to test and certify for advice.

It means the CPC (circuit protective conductor) could be smaller than the live conductors dependent on the type of cable you use. This may not be suitable in certain circumstances, so follow the advice given so far and get a qualified electrician in. He/she will be responsible for the design of the circuit if certifying it. I personally wouldn't certify something I have had no input in regarding the design, installation method and materials used.

Intoelectrics - should that say? "wouldn't"

If your 'electrician' is signing it off then I would suggest you speak to him/her to agree a circuit design suitable for your requirements.

Hi,

Many thanks for your replies, I was just seeking clarification/opinion as from what I read online I did not need SWA. Here is the email to him and the reply hence posting on here for others opinions.

My Question
"Hi Mark,
I will be shortly running some cabling into the garage (if you remember it is attached to the house so just going through the wall) I know you left a space on the consumer but I would like to know what cable to get please? I would like to go as large as possible to future proof things."

His Reply
"Good evening, You could run 6mm 3core SWA, that would allow up to 32A or 10mm 3core SWA up to 50A."

Get your electrician to explain why he would prefer SWA

'His' reply seems fair enough, unless the cable was covered by that itchy stuff (Tel recitation).

Edit; arrgh I see, the question is to swa or not swa.

That is... the question
