I am building another outbuilding to the rear of my home, I do have a garage which is fed by a 6mmsq cable from the CU in the house. the length of cable is approx 18m and is protected by a 65mA RCD in the CU. The new building is set further back and the length of cable from my existing garage to the new building is approx 33m. The purpose of the new build is for my son and his band to practice and record their music, they will have the usual musical instruments and amps. will 6mmsq T&E be ok or will I need to replace the cable rigt to the CU in the house to something heavier and should I use a 30mA RCD in the studio.
Sorry its a 63A RCCB and in the garage I have a 200ltr compressor 3hp motor and there is nothing running just what ever tools I use and 4 florescent lights.
and should I use a 30mA RCD in the studio. but its already protected is it not? and apart from lights and sockets will the outbuilding need any heating? x
No the heating will be oil fired, and I was going to use the RCD so as if there was a trip There would still be lights in the studio.
Thats correct but in the garage if there is a trip in the house the garage goes black, & I would like if I still had lights more so in the studio
Yes thats what I thought but what about the supply cable to the studio will 6mmsq be ok at that lenght ?
Not much help but thanks anyway this work shud be done by a qualified electrician 4 many reasons like UP x
A 6mm cable for that extended run from the garage to the studio will be adequate, for 'band practice" etc. A 6mm SWA XL cable will allow you around 5kW. You mentioned using 6mm T&E? Do you think that's wise? Lucia.
