All downstairs sockets spurred from upstairs ring main?

[Aragorn84]

yes, but if you want to take a spur from a spur as you describe, you need an FCU BEFORE the first socket.

Effectively you'd need two FCU's, one between the ring and the first socket, with a 13A fuse and preferably no switch, and then a second one in the spur going to the fire with a fuse suitable for the fire, and a switch if desired.


So you'd end up with:
[code:1]

RING ------- FCU -- Socket -- Switched FCU -- Fire

or

RING ------- FCU -- Socket
`-------------- Switched FCU -- Fire

[/code:1]

depending what was most convenient to wire it up.

If the FCU has a switch does this not then act as an isolator?

Yes, but it isolates everything down from it, so if you had just 1 FCU which was before the socket, you would isolate the socket as well as the fire.

Thanks I understand your comments. Would it be a big problem just to have a switched FCU before the switch?
I'm thinking I'd only want to isolate the fire for maintenance or decorating or worst case a real fire and in allm these scenarios I wouldnt need the double socket anyway (it will be used for TV and DVD).

So, Spur from ring main ---> Switched FCU ---> Double socket ---> Fire would be acceptable I think (and one less box too)
Alternatively would the following be acceptable?:
Spur from ring main ---> Switched FCU ---> with 2 "out" cables one to the double socket and one to the fire 9although I think the first option would be the better one)

The issue is the fire needs to be fused correctly. Given you said ti was a gas fire, the circuit is surely low current and only used for ignition or similar? It'll probably require a 3A fuse, and the only way to provide that is a second FCU...

Point taken!
I was working on the FCU needing a 13A fuse (originally the feed was going to be to an electric fire before my son changed his mind).
Understand totally now. Thanks
