Are you uo to date with BS7671???

Are you?

Are you?

Of course.

I got bored with all the cat fighting and haven't read the entire thread, so forgive me if I've said something that has already been said.

If you decide RCD is the way to go, Hager do a range of three-phase RCD's. They are not cheap, but you can often find them on ebay.fr second hand. There is nothing wrong with them. They are usually from domestice installations in the rural areas which are often three-phase and some UK sparkies change them to single-phase so the RCD's are just surplus. Search for "Hager differentiel tetra"

Hi Norah
Thanks for the advice on reading the regs..
In a commercial kitchen where would you put a 3 phase RCD protected socket to protect a piece of stationary equipment; such as say a twin deep fat fryer or a 20 grid combi oven?
That little book you hold so dear hasn’t got all the answers, what will you do now?

 

[Toneyz]

I’m not disputing the need for a plug and socket only the need for RCD protection..
Up until now equipment in this environment hasn’t needed to be considered for RCD protection..

Yes, but this all changed with the 18th.

Install a 32A 3 phase rotary switch instead?

Given the propensity of electric heating elements inside catering equipment to break down to earth I would want to fit RCD protection regardless. Better that (and an annoyed customer as the RCD starts tripping intermittently in the future!) than the black mess that will result from the circuit not disconnecting until the MCB pops.

Satisfactory Zs readings would be an essential requirement of any RA

Whilst this would be ideal so not having a socket neglects the need for RCD protection, the OP has stated that he is required to provide si=ockets.
