Let's see: 400W/12.7V = 31A. Really? Dam* right you should not!

Why not do it right?

AFAIK arc fault breakers are for 120V AC in homes and not DC. Never heard of an arc fault breaker for DC.

So what is going on?

Don
all the metal can 12v ATC breakers are too thick to fit in between other fuses

you have two choices make up an extension socket
or
leave the tabs long, cover the unused length of bare tab with heat shrink tubing
expose only the ends to fit in the fuse socket
let the breaker extend out and over the neighboring fuse

Thanks westend. Too thick to fit :(

My need is quite simple. I run a 400 watt inverter from a cigarette lighter plug (ya I know, I should not). So far I've only blown one breaker. Ummm that was 3 nights ago when I grabbed the wrong cord--and plug in an oil filled heater on the 600 watt setting. Fortunately I was in front of a Walmart (yes I do have a replacement in the RV but it was late and I was tired). Unfortunately they were out of 15 amp ones so I chose to buy a "kit" which was on a rack saying $12. Imagine my surprize at the till, when it came up as $34. The clerk marked it down and I decided I may as well have it. It has some sort of tester, but I'm too busy getting down the road to look at it.

I thought it may be a better solution--just as I replaced the 60 am OEM fuse with a "home brew" breaker. (It was god awful hard to solder, so I thought an "off the shelf" might be easier--and since I don't have an iron with me......)

Don, breakers to replace ATO-ATC plastic blade fuses are notoriously unreliably inaccurate. If you get a good one to begin with it will stay accurate. I just went through an O'Reilley 30 amp breaker and it was GARBAGE. I melted the brass tangs off of it testing it in front of their store. Go with delcity.net if you can. That auto parts chain is on my ---- list. They wanted $33 for a Chinese serpentine belt that cost $27 at a Dodge dealer. I do not know about what other parts stores carry. Most of the breakers have snap to length fit blades. Check before snapping too short. Some of these breakers must have all power removed before they will reset.

Thanks for reminding me. Tomorrow I fit a stud type breaker for the radiator fan. I would tend to trust a NAPA breaker. But delcity.net, Blue Seas and genuinedealz sell good stuff. JMHO

You will need to search for breakers
O'Reilly auto parts

120VAC Arc Fault Circuit Breakers are specialized breakers and expensive compared to a standard breaker.
