Ask your QuestionHi, i want to run an armoured cable from my garage consumer unit (which is fed from the main house consumer unit) to a garden room that would also have a consumer unit fitted to run LED lighting and small 13A power, is this an acceptable approach or can you not link consumer units? Thanks

"This will depend on a lot of factors the first being your main fuse is it a 60 or 100amp this may need to be changed depending what else the house is using etc next is the garage board what was that board installed for and what is it used to run and has it any spare ways to put a new circuit in and is it RCD or RCBO protected it really needs to be checked over before we can assess"

Just need to put the correct fuse in to protect the cable that is feeding the garden room"
"Hi you have to have a separate earth supply (outside earth rod) and would advise a separate fuse board fitting inside and local power and lighting from there would ideally need a 32amp supply from the main house with an armoured cable either buried or clipped direct. I could quote you if local, where about are you based?"

Answered on 11th Jan 2021 - Member since Dec 2020 - report"Yes you can supply from the sub board. It does depend on the load you are going to put on the new consumer unit. The design of the circuit will also need to be checked depending on at supply you have, and what is in the shed and if there are any metal extraneous parts in the shed.
Ask an electrician to give a quote to carry out the works and certify the installation."
