Hi,

The previous owner of my house has spurred a double socket off an
existing spurred double socket. I understand that this is against the
current regulations as well as being dangerous because of the potential
for excessive load on the cable to the first spur. To make it safe and
legal I think all I need to do is add a 13A FCU before the first spur.
Is this correct? I can't add them to the ring without disturbing a
nicely sanded floor.

I don't suppose there is such a thing as a combined FCU/double socket to
allow me to just replace the faceplate on the first spurred box (haven't
seen anything like this in the shops so I'm guessing not)? Or, will I
need to add a single box and FCU before the first spur?

Many thanks in advance for any help!

Cheers,
Grant

There are some triple sockets that have built in fusing. I wonder if a
manufacturer of these has a model with a fused output, as well? It's a very
long shot, though.

Not that I've seen, although you'd have to knock a triple box in
anyway so while you're at it it would be a lot lot cheaper to just
stick an FCU next to the existing double socket that everything is
spurred from.

I think you can get a double socket and fused spur from someone like
Hamilton but it is a custom made piece of equiopment AFAICR so is
likely to cost a fair whack.

Why not dig out the old back box and install a double one suitable for two
single plates. Fit one FCU and one single switchsocket. (Unless its
essential you have a twin socket at that point).

You'd still have to make the hole bigger to do that so you may as well
just stick a switched spur in alongside the existing double socket.

Would I need one with a fused output? If I make the triple socket the
first spur, wouldn't the fuse in it protect the wire to the first spur
against an overload from the triple itself and the double spurred from
it? Effectively I would be using the fuse in the triple to do the same
job as an FCU. What am I missing here?

Yes. It would share (would have to share) the fuse with its own sockets.

Yes.

against an overload from the triple itself and the double spurred from
it?

Only if it had a fused output. If you spur from its input, then no.

job as an FCU. What am I missing here?

Nothing, except that the accessory might not exist.

I think that's the slight, but crucial, downside.
