Fused spur question

[BenTen]

Hi guys,

I’m running some power outside.

There is a socket inside the lounge and I want to switch a supply from this out.

I was thinking of a 13A FCU Next to the socket. Then out the back to an outside 2 gang socket (IP66)

My main question is do I NEED to fuse down again for some lights if I keep the t and e current rating above the 13A for said lights.

you'd only need to fuse down if you reduced the cable size to below 1.5mm ( 19A ccc if no insulation). remember that fuse is to protect cable.

as an aside. the lights are a fixed load so only fault protection is needed.

Many thanks. My thoughts exactly.

lowest ccc in osg p155 for 1.5mm is 14.5A so good here.
So ok to feed lights straight from the socket. Just seems a bit odd, but don’t want to have to fit two FCU. That also seems odd!

many thanks

a second FCU would, though , be advantageous as a switch for the lights, and a means of isolation in case of a fault.
