E 23 250 amp main battery fuse
I ran into an issue with my main battery fuse on my outing in FL last week. I was experimenting with different heating options. The lows were around 30 degrees F and one night I ran the Houghton heat pump and a 1200-1500 watt cube heater. When both running it was drawing about 2500-2800 watts and worked fine on shore power and the inverter is I started them one at a time. I was running both on shore power over the night and awoke with no power at all in the trailer. After some trouble shooting I found the next camp site over had switched off my camp site breaker when leaving her camp site. After turning the breaker back on all seemed fine until I removed shore power and I had no DC or inverter power. Further trouble shooting lead to finding the main DC 250 amp breaker in the line after the DC power switch blown. I assume the surge to the inverter power after shore power dropped blew the fuse. I replaced the fuse with one from the auto parts store and all is well. I will be carrying as spare in the trailer from now on.
