Hi,
I need to wire 3ph 32Amp socket at work, does this socket need to be rcd protected if so what type rcd should i use 3ph rcd ?

Is the socket to be used to supply mobile equipment outdoors?
If yes, then it will require 30mA RCD protection by means of a 3phase RCD.
If no, then it will not require RCD protection.

you would need to check requirements with 411.3.3.

We just this week replaced an exisitng commando socket to switch isolator socket outlet at 32amp 3phase and earth for a crane lifting device that is mobile. We did not install RCD due to unwanted tripping and the fact our client has spend some considerable £ sending two of its workforce to Germany for training and operation is restricted to use of a key.

I would call that skilled person as they have to install the 10meter trailing socket overhead using the crains lifting gear to lift cable from the ground to prevent damage etc.

Not aware that there are any exceptions for providing RCD protection for mobile equipment outdoors.
Hopefully, it won't come back and bite you.
