Dead circuit!

[rmroy]

Hi, I'm back again with another confusing (to me) problem. I turned on a space heater that I didn't realize was plugged into a circuit that has the dinette receptacles, TVs, blu-ray, inverter etc. The circuit died, and the breaker was not tripped. I tried to reset it, powered everything on and off several times but not luck.

The inverter still hums when I turn it on but gives no power to the circuit. The breaker looks fine but I haven't taken a close look at it yet.

This is a 2018 classic, so I would expect the breaker should still be good.

Any ideas?

Check the inverter it has a circuit breaker or fuse on it somewhere, varies by make and model as far as where and which it has.

I will look for that, but would the inverter take the entire circuit out? It wasn't on when the circuit died.

The WFCO inverter that's used in my '17 Flying Cloud has a "Class G" melamine tube fuse. I found this out by doing exactly what you did, plugging a heater into a convenient outlet while on shore power. I'm not sure if it's the same fuse on yours, but it's under a twist-on cap on the body of the inverter. It looks like the attached image. It wasn't expensive but it wasn't readily available on a weekend in Fredericksburg, TX.

The particular replacement I bought for the inverter on my Flying Cloud:
Bussmann BP/SC-15 15 Amp Time-Delay Class G Melamine Tube, 600V UL

The fuse that came out was a Littelfuse SLC-15A class G.

The inverter is a "pass-through" type, so you don't need dedicated inverter receptacles. The power passes though a fuse in the inverter whether it's inverted from the batteries or passed through from shore power.

rmroy, I checked the WFCO manual for our 5100 Inverter (2019 Globetrotter) and while there’s an AC pass through circuit, it is fused.

Here’s some screen shots from the Owner’s manual. Hope that helps!

Found the inverter under the lower sink drawer, found the strange little breaker, pushed it in, and now ... the circuit works perfectly!!!

Thanks so much to all of you. This forum and all you members are great!
