Immersion spur

[haj]

Good evening gentlemen i been asked to put switched fused spur in the airing cupboard for a shower pump the customer says the plumber says just tag it on to the immersion ! What's everybody's take on this ?

 

[dingledong]

if its only a 3 amp pump why cant you come or the immersion it would then be a 20 amp cicuit with a 13 and a 3 amp load on it ..... whats wrong with that

No issues with The load aspect nor the discrimination provided by the fuses.
However.
I still wouldn't do it due to page 177 in on-site guide.
H5:
"water heaters fitted to storage vessels in excess of 15 litres..... should be supplied by their own circuit.".
Purely ar*e covering I know. But it's not much more work taking it from the lighting loop in the loft.

Apologies.
Long day, tired eyes. !!
replace the word "ring" for "loop".

I know the feeling mate.

Sorry to point it out..... I just couldn't help myself.

gt1 i can see your point but these guides are just that so i think i could argue that point when i go to the great niceic in the sky

 

[GT1]

Oh I agree. They are just a guide.
But then so is the 17th to be fair.
ie. not mandatory. !!
It's only if things go wrong that it becomes an issue when work has been done contrary to a written down "guide".
Seriously, I've no issues with the engineering of it, and it makes perfect sense. Just saying I'd rather stick to what's written if there's a choice.

I think its down to what you feel comfortable doing and making sure you cover yourself in what ever choice you make. Im with GT1 though I would always try my best to stick to the 'guide' for ease of covering ones behind.

 

[dingledong]

dan the size of my behind takes a lot of covering so i've given up

When doing a PIR (EICR) that's what you use to compare against though, so there is a difference
