Shower Isolator yes or no as safe isolation

[Loki]

Hi,

Just want to get some clarification on something for my NVQ portfolio.
I have changed a shower & done the testing etc & have written this up for my portfolio.
In my write up, I said I safely isolated the shower supply via the shower isolator switch which was located in the bathroom next to me where i was working. I ticked the box for safe Isolation in my write up. My assessor said this cannot be classed as safe isolation because you cant lock off a pull cord switch.

Should I just untick the box & accept what they say or should I push it & say it was safe isolation as the isolator was in the room next to me while i was working & couldnt be energised without me noticing?

Think I will just untick the box

Hager WMCS50N 50A shower isolator pullcord switch - BS EN 60669-2-4

18th Edition regs say yes as isolating switch on
TABLE 537.4 – Guidance on the selection of protective, isolation
and switching devices - page 181


Thanks

Michael

Have to agree with your assessor. No RAMS would accept turning of a switch as ‘safe’ isolation.

The pull switch is deemed an isolator but if it is not lockable and not under your control then other methods must be put in place.

Ok thanks for clarifying that for me & for the quick replies.
I won't use this then for portfolio this time as we get shower replacements weekly lol. I'll just make sure from now on I isolate at the CU & lock off.

Thanks again

Michael

With MK cord pulls, you can unscrew the cord.

That would not prevent someone pulling it back on.

They would have to be tall.

They'd use the steps left by the person who removed it, unless they'd locked them off..

Sometimes Spin I think you argue for the sake of it.

Only sometimes?

Oh good.
For a minute or two there, I thought everyone here had no sense of humour.
