They can be made a lot cheaper by taking advantage of the zero crossings of AC. A natural arc extinguisher.

I would not have thought it was different, I'd just think 15 amps is 15 amps.

I wired up a bunch of solar panels once with a regular light switch to shut off each string. Those AC rated light switches all shorted out about the second time I used them.

They both say they're good for DC so hopefully that holds true.

Contact will arc and weld or arc and burn off if it is not designed for DC.

So there is never a low current condition unless the load is wildly variable (which is not typical). In an AC circuit, you have a zero crossing 120 times per second. So there is a low current (zero actually) condition every time it crosses zero. Eliminates the arcing issue. bp <part15sbs{at}gmail{dot}com>On 1/11/2022 10:02 AM, Josh Luthman wrote: DC.

All I can find are 100a breakers that won't hold big enough wire (wtf?) or a fuse holder which would work but I'd rather have a breaker if I can.
