Question

I had a parabolic heater running on high, which I've done before, when I smell what I assumed was hair. Typical for these heaters with the exposed coil. Then I noticed the heater was off. The wall plug was dead but the circuit breaker is still set, not thrown.
Appears the wiring opened somewhere between the circuit panel and the outlets. The outlets are in the kitchen slide out. The wiring under the slide has a couple 3/8" round cables which resemble a power cord. One for outlets, one for microwave, I assume. Makes sense for a slide to use stranded wire. The circuit panel is all 14/2 and 12/2 house wiring. The back side of the circuit panel is under the sink and a rats nest. The wiring is in plastic sleeving then all spray foamed together (rattle resistance?). Hard to trace and keeps the wires warm, not nice.
Any idea where the two cables are joined (cord to 14/2)? Should be in a circuit box similar to house wiring.

First place I would check is the receptacle that was connected to the heater. If a wire burnt off the cheap connectors on the receptacle, it won't trip a breaker.

I agree with westend. I have seen this happen in a freinds house. The electric heater had actualy melted the wire in the back of the plug. And that plug and all of them down the line went dead.
For this reason I NEVER run an electric heater on high in my RV.
I have used the same electric heater on LOW for 12 years and never had a problem.

Check inside the kitchen cabinet, right next to the converter. is a junction box. I have two SO cords on one side and the other side has two building wires going to the breaker box. Might be what you are looking for. I have not traced mine out, but that night help you. If not I can try to trace mine out. in a few days

Found the bugger. Noticed the circuit breaker was marked Kitchen GFCI. The Bathroom GFCI breaker goes to a GFCI on the front of the bathroom sink, so assumed there must be a kitchen GFCI. Looked all over the kitchen, pulled the plugs under the upper cabinets, ...
Turns out there is a plug under the drop down counter on the side of the sink. Can't see it when the counter is down and never leave it up. The neutral wire and GFCI contact was fried. Explains the smell under the sink.

I take it this "plug" is an Outlet... And it's also serving as a pass through, where one wire feeds it then it feeds another wire to another outlet. Like This...

The outlets serve as a junction box and connections.

There's been a rash of failures in these connections lately. I finally had one, junction box powering the water heater. Maybe it's worse with cold weather.

Here's another point of failure: Junction of stranded Shore Tie with solid Coach wiring. Running two "small" electric heaters will keep the coach's total load below 30-amps. BUT it's been found to ruin the connection. Connection can be re-done, but it seems all too many connections are just slapped together.
