Fused spur timer

[alchemist]

A customer has a heater off a fused spur, they want to put a timer on it.

FCUs with inbuilt timers are expensive. Can I use an immersion heater timer, I worried it might not be fused?

If you put the timer after the spur unit it will be fused...

Well it's not, so yes, I'd be worried too. Either fit it after the existing fused spur or fit the proper kit for the job. Price should be secondary to the primary concern of it being somewhere near being done correctly.

I was thinking of adding it after the existing FCU, just wondered if I was missing some other obvious way of doing it.

Will be up to the customer if they want to spend an extra

i got some FCU timers a while back. IIRC, they were

Not too dear?

you'll spend that in extra parts and labour if you add a separate timer.

Never seen any other type TBH.

as patch says, keep the job simple and buy the spur/timer.

is the fuse really needed? maybe just get a timer instead.

Depends on manufactures instructions, but I presume it will have come with a plug top so I would deffinatley say yes.

Presume? How can you presume something and then say definitely?

If it is a 3KW heater and it is on a 16A radial does it need the fuse? Presume so? Definitely yes? Or not at all?

doesnt always need it. un-necessary fuses can only cause trouble later.

if its a 3KW heater on a B16, then the B16 can protect it. after all, the B16 would most likely go before the fuse anyway

That's what you said before. Why definitely fuse it? 3KW load on a 16A radial, no fuse needed but you'd fuse it anyway? You must be one of those people who goes OTT and fuses everything whether BS7671:2008 calls for it or not.

and skip the fuse where there should really be one

Still on that one children?

The customer has agreed on the fused timer, so went for the one on TLC.

It's a heated towel rail so I expect it's fairly low power and has a smallish cord, so will fuse it at 3A if less than 700W and 13A otherwise.

Sound right?
