What S.I. under risk assessement for omission of RCD in regs

The Ghost · Oct 12, 2018

Ok so as I am moving VERY soon I have packed and sealed all my electrical books away. I don't have access to regs consequently. I am racking my brains regards risk assessment for omission of RCD on sockets. If you read the fine print it references a statutory instrument regards the standard this risk assessment must be made to. In my memory it is S.I. 19 HSA available at the HSE site. Can anyone have a look under 433(I think) and tell me what that S.I. is? I need to advise a customer and better get it right.

Hi - in the 17th Reg 411.3.3 refers. It's Note 3 takes us to App2 item 10 for risk assessment. Not sure if this is it so hit me again if needed.

It is Reg 411.

17th references ‘SI 1999 No 3242’

18th has removed this reference and instead says risk assessment should involve electrically skilled person.

Statutory Instruments, followed by a number ie SI 341

Yeh at 10 on the lower picture @Wilko thanks for that and @essex for the info. That is what I was referring to. Thanks again. Can now finish my email to client!

Maybe it’s because you’ve put the wrong SI number in your post?

I added the number as an example Dave, not as a reference, now stop being picky, anyway the post was meant in jest.

I am interested Vorts why the omission, new install or something with an existing circuit.

To be honest, I have just reread the question, my bad I thought that the OP wondered what SI meant, realise he did know, and was just after the number, no excuses, sorry for any confusion.

I've recently had a customer and a designer refuse to give me a copy of their risk assessment for omission of RCDs, they expected me to put my name to it.

My comment of 'jog on' in slightly stronger language and my directors pulling the project had the desired impact.

I am/have put a cable in for a comms room on the third floor of a commercial building in a locked cupboard accessible by only competent persons (hrmm. so say!) Anyway I have dropped out of the work because of moving so it's a handover and just advising client I have arranged an RCBO from the LL supply and there is a spare MCB as well. Just a courtesy really for the next guy who finishes it. And thought to advise the client regards RA in leaving out an RCD in this instance. All communications and internet will go through this comms room so it is mission critical and moot as to additional protection. Personally I would put it on an MCB. What say you?

Honesty always the best policy, but rather than be rude about your post as some might be I thought more diplomatic to pass over it.

It is not likely to be used for general use whilst it is a comms room so I would omit.

And it certainly wont be used for equipment outside on the second (correction!) floor. Also it will be a commando socket so even less likely to be used by the cleaner who broke into the comms cupboard.
