can anyone tell me what amp fuse should be in the plug of a basic dawn to

TIA


Generally, you'd divide the wattage by the voltage of the
lights, and round up to the nearest integer.


In the US, (where you probably aren't, since you're talking
about fused plugs) a typical set up is two 75 watt floods,
at 110V, so 2 amps.
oh dear!
I am in UK. There may be 2 amp fuses but I haven't heard of them in common
use. Think it must be different over here. The plugs are 13 amp and
sometimes they have a 5 amp fuse and sometimes a 13 amp. Thanks for your
reply though I think I might have to look in the uk groups???


Use the smallest available fuse that exceeds the draw of the lamps.
If the choice is 5 or 13, go with 5. (it is unlikely that
a household security light would be eating more than 1100 watts.)
