UK Spur in kitchen question

[shaunster]

Hi, I have a question about a kitchen spur.

Currently fitting a kitchen for my brother, he is having a built in microwave in a wall unit and I took a spur from a double socket off the ring and ran it to a single socket in the wall behind the cupboard above the microwave.
Now he tells me he also wants under cabinet lighting, is it permitted to extend from this single socket to a FCU with 3 amp fuse to power the lights?

I have conflicting advice on this, I have no doubt it will work but is it permitted?

Microwave is 1900w and is designed to go in a wall unit.

Thanks

Welcome to the forum mate.
Is the circuit you have extended RCD protected?
When you say you fitted a socket "behind the cupboard" do you mean that the socket is not accessible?
If you was to put a FCU just after the double socket (before your single socket) then you can have more than 1 spare.

Welcome to the forum mate.

Thanks.

Sorry I meant the plug socket is in the wall not fixed to the unit, a hole will be cut in the back of the unit so access to the plug is maintained. Circuit has RCD protection.

In a perfect world you want some way to isolate the microwave without having to drag it out first

But in the real world probably half the appliances in use are just directly plugged into a simple 13a socket at the rear

It will be, plug is in wall unit above microwave.

In your last comment are you suggesting a multiple outlet spur. I agree the chance of overload is probably non existent however this would be non compliant.

Is a 13a FCU before microwave, and then dropping down to a 3a FCU for lights on the same spur permitted?

Yes, as the circuit after the FCU is protested by the 13A fuse.

This is his how most conservatory firms I see will wire up a new conservatory.
They will nick a feed of a socket then add a fuse spur then stick everything in the conservatory circuit power and lights into that one spur

As long as the customer has been informed that they are limited to 13A then everything is fine.
Might cause I a bit of a problem if they want to bung a 3kw heater in there in winter along with other appliances.

Some also do power to sheds this way as well.
