Cable Size And Amperage It Can Carry

[Lordy9099]

Hello,

I just bought a LED security light drawing 3.6W and used a 0.75mm cable to run in inside then into a fused switch spur, and a cable from a 1G plug socket next to it to create a spur, will the 0.75mm cable be OK to carry the current? And what fuse will be safe for the fused switch spur?

Thanks

come off your socket outlet in 2.5mm to adjacent FCU, then fit a 3A fuse, the 0.75mm will be fine. as the 0.75mm is quite small, fit ferrules to the terminations in the FCU.

hmm , let me see , 3.6w , yep 0.75 should be fine lol.
3amp fuse for the spur.

 

[Lordy9099]

Can I not come off the socket in 0.75mm because the light is only drawing 3A and 0.75mm is rated at 6A?

Thanks

Put a plug on the flex, 3 amp fuse and plug into the socket!!

Not helpful. Just a very pathetic comment.

Hello,

At the moment it is 12:20AM and I really do not want to be messing with electric at this time at night, will the 0.75mm be OK for the moment?

Thanks

Hello,

But won't the Fused Spur Still be drawing power?

Thanks

Yes there is. There is a Fused Switch Spur with a 3A fuse installed in it.

Thanks

out of interest which room in the house is the socket you have put the spur by?

 

[jaydee81]

was told on my last nic inspection that the smallest cable you can connect to a fused spur off a ring main is 1.5mm inspector picked me up on it as i had fed 150 w towel rail element through switched spur with 3 amp fuse fitted

 

[jaydee81]

should read that i fed it with 1mm through switched spur with 3 amp fuse fitted

That is correct if considering T&E from the ring to the FCU on power circuits.
