Electrical LED lights

Post by Bongolia » Wed May 17, 2017 11:46 am

Right I am at the stage where I am about to wire the interior lighting for the Wasp. I have 5 off 5 watt LED units to fit on a separate ring circuit.
What cable size should I use ( I have a roll of 4 amp [-o< ) and what fuse rating would be recommended for this?

You fuse for the rating of the cable, the fuses ONLY protect the cable, not the devices on the circuit!
A 5Watt LED will draw 5/12 Amps and there are 5 of them so 2Amps.

So 4 amp cable is Ok then?
And just one fuse?

Yes 4Amp is fine and 1 fuse you don't need a ring main your cable is adequate to handle the current without a ring!

The rating of the switch also needs to be adequate for the load.
