I got there a long time ago.

It’s a very fine balancing act you know

He is explaining himself poorly but I am actually with Charlie here.

If ever there was a socket to be risk assessed out of requiring an RCD then it is this.

1. The 3 phase socket is only going to be used for one item of equipment.

2. The socket can be labelled so that it is clear only this equipment can be used with it. No other equipment can be used.

3. It could be added that the appliance will be tested annually to confirm it is safe for continued use.

4. The socket is not near an external door so that temptation to use it for external portable appliances is not there.

All these questions would form a part of the risk assessment to negate the need for a RCD protecting the socket.

I have assessed out RCDs a few times.

Thank you for that input!
I’m guilty of not going into things in too much detail as in my head I know what’s right and automatically think others do.. cheers Essex

Omitting RCD protection for stationary equipment that will only ever be unplugged for replacement or servicing by skilled/competent persons is one thing.
Omitting RCD protection for equipment that will routinely be unplugged for cleaning by ordinary persons is another.

I honestly think that if you were willing to sign a Risk Assessment stating RCD protection is not required in this instance, you would be considered incompetent or a fraudster in a court of law.

Once that piece of stationary equipment is unplugged it is isolated from the supply..
That instructed person will only ever plug that same piece of stationary equipment back into that same socket..

How can you guarantee that the person unplugging the equipment will be instructed?
How can you guarantee that the equipment will always be plugged back into the same socket-outlet?
What difference would it make whether the equipment is or isn’t plugged back into the same socket anyway?
