hey its not my fault if people dont like me i tell it like it is, i don't know everything, but i know a lot ... and yes, ac and dc are different....

DudeBud

AC/DC Rocks

LOL

mike87

they want almost $100 for a curcuit breaker at magnolia but ill just get one online thnaks

live277

capacitor,yes
automotive fuses and breakers ,yes
breaker from a house (or romex for that matter),NO!!!!
100amp breakers for a house are 2-pole single phase and have a different rating.
ac and dc are 2 different animals altogether

Yes, you were right.

AC is "alternating current", DC is "direct current". Your house is running on 110v AC, the truck is on 12v DC.

A DC circuit has distinct postive and negative sides, and current flows only one direction (negative to positive - not a typo btw). In an AC circuit, current switches directions many times a second. In the US, AC current flops 60 time/second (60 hertz or 60Hz) and in Europe AC current flops at a rate of 50Hz.

The properties of when one type of current flow becomes "better" or "worse" is a bit complicated to show, but the short form is that AC devices (such as motors) will tend to run cooler than comparable DC types; though the DC types will tend to have more torque and be less complex.

Generating DC current from a storage device is "easy" compared to AC, hence you not seeing a lot of AC batteries in flashlights. Generating AC when you can tie into something spinning is easy, hence the alternator generating AC - (and then "half wave rectified" to generate DC so that it will charge the battery).


Yes, the measure of the flow of current will be the same, given that amperage (current) is a measure of how fast the electrons are moving. But, there are many more electrons present in a 110v system than in a 12v system. And, in the scope of this discussion (about circuit breakers) a 110v breaker will NOT operate the same in a 12v circuit. Current flow is only a part of the physics of how a circuit breaker works.

I'd say go with a DC circuit breaker becuase AC and DC are alot different.

AC is alternating current and DC is direct. I'd say it's safe to assume the 2 generate very different magnetic fields.

If a breaker runs off a magnetic field produced by certain amounts of electricity, it may not pop open and break the circuit for you, even if it is way above the amperage on the breaker.

Stay with caution and blow the money on a new one.

Thanks for clearing that up for me Mark! I remembered that AC current alternated paths unlike DC but wasnt sure if I was dreaming that or what.
