Re: Headlight Circuit Breaker Question

If I did my electrical math properly, to get the exact same protection as the original 6 volt breaker you'd have to use a 12 volt breaker with half the amp rating. Realistically, if your wiring is all in good condition you shouldn't have a problem with the 12v. A 12 volt fuse or breaker would blow or trip slower than the 6 volt of the same amperage. For instance: A 6volt 100 watt bulb uses 16.66 amps, but a 12 volt 100watt bulb would use 8.33 amps to generate the same light.
My only qualifications are industrial electric. This stuff is just on a smaller scale.
