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.

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,

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

Thanks
