Fusing an Additional Socket

I just bought a ABR sidewinder marine plug rated at 20amps. Can I run a 20 amp fuse with this plug ????

Cheers,

Yes mate absolutely. You've just got to make sure your cable size is adequate which I'm sure it is.

As per my previous post, don't fuse your outlets higher than their rating. By all means go lower just not higher.

Most fridge plugs also have fuses built into the plug so no need to worry about the fuse size on the outlet, unless of course it doesn't have a fuse. Confused? haha

I put the same plug in as you and also a "cigar" plug. I put a 20A fuse on the hella and a 10A fuse on the Cigar outlet. All as per their current ratings.

Also it's not ideal to put a CB on an outlet as it will keep closing onto a fault if you're not aware of what's going on.

Farmers are a good at this, they like to test the wiring by chucking on as many lights as possible. I have seen many melted wires on headers and tractors. some are brighter than small towns. A nightmare to fix sometimes.

As some have suggested, everything should be fused!

I design and instal electrical systems from 66 000 volts down to millivolts - and everything is protected by fuses, circuit breakers, fusable links or the like. Only short runs of cable are allowed unprotected and must have substantial mechanical protection to prevent damage and short circuits.

If not, in the event of a short circuit, the cable becomes a fuse! Normal automotive cable can handle the short circuit capability of a battery for at least several seconds - and will get very hot in the process.

Melted wiring insulation and anything else near it will result. Not only is it a nightmare to sort out, but the last thing you want to be doing away from civilisation!
