FCU inc socket? or two spurs or something else?

[twm.bwen]

I would like to add a socket (only single needed) and a washing machine point in our untilty room.
I am aware I can take a single spur from a socket on the main ring to supply a single, double or triple socket or FCU for a subcercuit for eg a washing machine.

I am also aware I cannot spur off a spur (ie feed FCU off spurred double socket.)

This seems odd considering a triple could be drawing more power along the spur than a single socket and 13A FCU. But I'm not arguing with Part P

The space available to me for mounting the above is limited and a 2G unit would be perfect.

I am aware you can get a 45A dp cooker switch with an integal socket. Obviously I can't supplu the machine with one of them. But does anyone know if there is a switched FCU (neon preferable) with 13A socket on the market?

If not I can only assume I will have to run two spurs (each from a different point on the ring). And mount two 1G units (which will take more room than a 2G

Is this correct, can anyone think of another way round?

THanks

If your existing SO is on a ring you could change that single SO for a double SO but given its location with washing machines tumble driers etc you'd need to be careful about the loading.

If it's a spur then you can't spur off a spur but you could change the existing spurred single socket outlet to a fused connection unit at 13A and have any number of socket outlets off that FCU. The number doesnt matter as the 13A fuse in the FCU will limit the total load.

Can always use twin boxes rather than a double box - although they are slightly bigger

Not aware of a switched FCU with 13A socket - sounds rather a contradiction in terms.

Hi there and thanks for the reply. I think you have answered my query but to clarify. There is no existing spur. I would create one/two to supply a socket above a worksurface and a w/machine below (I figure a switched fcu above w/s to 1g socket below).

From what you're saying I could take a spur from the ring main to an 13A FCU, and from that take one cable to a switched socket (dbl or sgl) above the surface AND another to a single unswitched socket below for the w/machine.

And this would comply with standards. Correct?

If so thanks, if not anyother ideas?

By the way, triple sockets can only draw 13 amps total. They have a fuse in them.

Thanks Steve, but only room for double above surface.

So is Cremeegg correct, if my spur is protected by a 13A FCU I can indeed have a double skt above and single (or even) double below for appliances?

If so would I wire them on seperate cables from the FCU (parallel?) or what would affectively amount to a spur of the double down to the socket to supply w/machine (series?).

I can see the FCU would protect but it does all seem a little odd.

Thanks
Again,
Tom

Hi.
Cremeegg is quite right, if you put a spur on the ring you can use it to feed as many outlets as you like as the spur limits the load of the additional points to a maximum of 13amps.

Good practice suggests you wire point to point and not in parallel as you put it, however, in reality if they are both connected on the load side of the spur the job is being done just the same.

Safety first!!
