Hi there
New to this forum. This was where I was directed by a couple friends to get help with technical issues.
I just brought my fifth wheel back home from storage and started in on a rotten floor issue that I unfortunately discovered after purchasing the unit a year and a half ago.
Anyway....
I have the trailer plugged in to a 15 amp plug in the house directly with adapters on the heavy 50 amp cord from the trailer. I was using a heater last night to dry some floor leveling compound and had the breaker in the house trip a couple times when I overloaded the circuit trying to run anything else. Nothing tripped on the trailer panel. Not a big deal but this morning I was using my skill saw plug inside and I lost power when the heater tried to start at the same time. Went in the house but the breaker was not tripped there and I still had power at the receptical where the RV was plugged in.
The RV has a solar pannel and 4 six volts but no generator installed. I believe the switch in the attached photos is to automatically switch in between generator power and 110, but not entirely sure. I am also a little lost in terms of what all the electical โstuffโ at the front compartment actually does. It does seem quite extensive compared to our other RVโs.
I did not unplug the RV cord (I know I should have!) and I heard a noise coming from the switch box and heard the microwave beap indicating the 110 power return to the RV on its own. Knowing there was an issue in the box I unplugged the trailer and took the cover off.
I could see that the white wire leading to the box was burnt at the connection and the insulation had melted back a few inches.
I would appreciate any input as to what might have caused this. Is the switch even necessary if I dont have a generator installed?
We have had the fifth wheel plugged in living in it for a couple months before without issue. That was at RV parks both on 30 and 50 amp services. I know the circuit in the house I was plugged to is quite overloaded. This may be a stupid question but could that have something to do with it. I would assume not, as something should have tripped, either at the house or in the RV.
Thank you in advance for any suugestions or input.
Gary
