Electric supply to boiler

[bewsh]

I've heard different rules from different engineers about the electric supply to boilers. My one mate who's an installer for BG says it has to be supplied via a switchable fuse spur and you can't just have a fused plug socket.

One of the guys I work with reckons that you can either have a switched fuse spur or a plug which goes in to a non-switchable socket so you physically have to pull the plug out to kill the power, rather than just pressing the off button.

Anyone know if these are regs or just good practice?

the fella you work with is 100% correct, your BG man is not

:iagree:

I thought so. And my BG mate made us pay some sparky to put a spur in when we could have used the plug socket!

Is it NCS or is it just electric regs?

What are you asking is NCS or electric regs, a boiler on a plug top?
Read the MI for the boiler and it will tell you how it should be connected, it might tell you to refer to BS ???? Which you might need a spark to clarify for you
Basically the boiler MI will be looking for complete isolation, which a plug top meets but get a spark to confirm, NOT your BG mate who is quoting THEIR rules not the regs

Can't get much safer than unplugging the boiler in terms of isolation lol.

As I understand it a fixed appliance needs to be connected via a switched fused spur and a boiler counts as a fixed appliance.

Should be double pole isolation too

As I understand it, a plug/socket is fine....but a lot of engineers sneer at the idea.

I tend to fit a switched, fused spur but I don't mind at all when I see a boiler wired back to a plug!

Sorry but I think a fixed appliance needs to be wired via a switched fused spur. I will check wiring reg's and apologise if I am wrong but I don't think a three pin plug complies with 17th edition reg's

a plug removed fm a socket is sooo safe omho,

I'm actually a big enough loser to have looked up the regs on fixed appliances in 17th edition. Since I'm hoping to be doing ACS soon it sounded like the kind of thing I should check. As far as the reg on fixed equipment goes it's number 537.3.2.1 and plug and socket outlet is acceptable. Whether there is something somewhere else in the regs I don't know. I feel like such a geek.

As said, needs to be an unswitched socket or a switched fused spur.

Switched sockets can be switched on the live only so doesn't give enough means of isolation for a lazy engineer that will just switch it off instead of unplugging it.

Who is an omho ?
