Power for condensing Boiler

[bluemooner]

I'm having a new boiler installed in my loft this weekend.

For power it requires a switched fused spur.

Question is where can I take power from ? I assume I can't hook it up to the lighting circuit.

I have a plug socket on the wall of the cylinder cupboard which is in the perfect place for me to run a cable up frm, but I have already spurred off that for the pump of the power shower.

I believe it's taboo to spur off a spur....

Any suggestions would be appreciated.

The usual source would be the ring main, (either at an existing mid-ring socket or with a joint box) though a dedicated radial from the fuseboard has advantages for servicing.
We may need a better description of whats already there to be much help.

OK cheers, I'll do a little digging for the ring main.

But just to clarify...

If I have already spurred of a plugsocket for the powershower, I can't take another spur off that socket ?

Could I take a feed off the socket to a connector and then split out one feed for the power shower and one for the boiler ?

It's more to do with location than anything else as I can run the cable up the inside of the cylinder cupboard without any disruption.

If you want to feed more than 1 load from the same spur point from the ring main, then at least have a fused switch unit in that line to limit the total load to 13A. If the total load is more than 13A you will need to find and extend the ring main properly.

That would be perfect.

So would it be better to go .....

spur from socket - fused switch - Connector block - LOAD1 / LOAD2

Or would you just connect both loads to the 'load' side of the fused switch ?

I was hoping I could do it this way. I just thought it would result in men in black polo-necks absailing down the side of the house and crashing in through the windows.

I always try to stick to the best/correct way and always seek advice.

Thanks again for your help. You're a star.

the correct way would be

spur from socket - fused spur (load 1) - fused spur (load 2)

Ah I see, so the first fused spur takes the total load & blows if it exceeds 13A.

That is how I wanted to do it initially, but when I read the do's and don'ts, I thought I couldn't have two loads spurred from one socket.

Thanks for you help chaps.
