I wan’t aware that stating facts was rude?
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..
Why are people so dead set against having RCD protection fitted to these socket outlets?
There are very specific circumstances where the 30ma RCD can cause genuine problems. One i deal with regularly is sockets to supply temporary electrical distribution for entertainment ie sound and lighting for festivals. The overall earth leakage of the connected equipment can add up fast without being near 32amp load. These sockets generally connect to portable power distribution that has individual rcbo’s on each circuit. The original proposal to rase the requirements for rcd’s to 63amp where thankfully dropped.
But this is way off topic. Apologies.
I work in the same area, theatre and outdoor events. 30mA RCDs don't cause problems, the inappropriate use of them causes the problems.
I can't say I've ever had a problem providing 30mA RCD protection to final circuits.
Problems only happen when people do stupid things like putting distribution circuits on 30mA RCD.
Why are people so dead set against having RCD protection fitted to these socket outlets?
Yes exactly. Im talking about the supply socket for the distribution to connect to.
Are you telling us that you get such RAs accepted by National Rail and TFL?Not dead against. Just accepting that they are not always required and are not always necessary.
For example we install 32A TP+N sockets for retail kiosks on stations. We do not install these on RCDs as they will ultimately be distribution circuits so our risk assessment will insist that the kiosk will have all circuits independently protected by RCDs.

Yep,that is the right way.? But socket outlets up to 32amp require RCD protection. Or is there a way around this ?
Are you sure about what you are saying here??I suggest you read back through the thread from the start!
I have only given constructive advice!
Please prove otherwise..
I have been involved in the installation and repair of commercial catering equipment for 25 years, I am an approved engineer for many brands.
What has been suggested is totally unnecessary..
just because you can’t do something doesn’t mean that it can’t be done, a risk assessment in this instance would be easy enough..
It’s stationary equipment that doesn’t need RCD protection

You need to read the regulation 411.3.3.I’m not disputing the need for a plug and socket only the need for RCD protection..

ExactlyHow 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?
