Hi Phil, I just use a 13A mains fuse. They give good protection and are very rugged.

Hello John J ---- are you sure that's a good idea ?? Your  domestic home fuse is rated at 10 Amp but designed for 220 / 240 Volts AC.  This means that the average ( or RMS value) amount of energy to blow this will be approximately 110 x 10 = 1,100 Watts.  The fuse rated for the Enfield is 20 Amp in a 12 Volt DC circuit. The actual energy used to blow this one is 12 x 20 = 240 Watts. Your 10A domestic fuse, in the event of a short circuit, will do more damage by way of causing overheating to the very wiring loom it's meant to protect. Check-out  -- Root Mean Square Values for AC Curent ---- on Google.  Heavy reading if it's new stuff to you but essentially gives the same info.

Hi Alen R, Understand your maths but your assumptions are wrong. It's only the fuse rating and fuse resistance that's important. If you measure the fuse resistance of a 13A domestic fuse you will find it is very little different to the standard Bullet fuse.

Interesting conflict of thought. I can see both sides, certainly watts is volts times amps, but maybe amps is amps whatever the voltage.


In an emergency I would rather have a domestic fuse then a nail.


However long term, a blade fuse holder and pack of fuses is so cheap why would anyone fit anything else. To add confusion, the wiring diagram in my workshop manual says it should be 15Amp!
