Consumer unit in each outbuilding

[peterhyper]

I recently quoted work for a guy which included a new consumer unit (TNS), and then noted that his summerhouse (about 40' from the house) and garage (a further 20' from the summerhouse) didn't have consumer units in them (Both had sockets and lights in them), so I made him aware that they both required seperate consumers units.

The chap (potential customer) emailed me to say that the other company who quoted him said that neither the detached garage or detached summerhouse required consumer units as they would be RCD protected at the house RCD. He even gave me the details of the company (who are also NICEIC registered).

I never try to sell unnecessary work to anyone, but both outbuildings are detached and both have light circuits and socket circuits and unless I am losing the plot due to the hot weather or old age (possibly both), they both require their own consumer units, or should I put myself on a basics training course?

Which scheme?
Which regs did he quote?

Stroma, and I can't remember if he even stated a reg. His explanation was that if the cable was damaged between the outbuilding and the house CU, it would not be RCD protected as only the ciruits within the outbuilding would be protected by the RCD.

Which is why cables should be suitably installed for the environment and an rcd is not a means of protection if correct measures are not employed.

This thread crosses STROMA off my list of possible CPS choices.

That makes no sense to me, unless I’m missing something obvious after enjoying a bubbly blonde from Belguim.

At this point in the thread we don’t know what the submain cables are and the installation method.... so maybe the assessor has a point

Maybe not, but the OP hasn't given any information to back up their claims even though they have replied to the thread.

What, giving rcd protection for incorrectly installed circuits.
