They have covered it. Some Motor homes you have to manually TRANSFER the plug to an outlet on the MH
Some have an automatic transfer switch (More in a bit)
And the breakers on the generator, Mine do not have a "TRIPPED" position, just on and off, Off doubles as tripped, So, since it is very hard to see the on/off indicators less the sun is just right they LOOK on when in fact they are not.
I have fixed that with a label maker Now OFF is clearly marked.
The transfer switch.. We keep reading the question "Will it hurt anything if I start the generator while plugged into shore power?"
The answer is,,,, Possibly.. If you have heavy loads, epically INDUCTIVE loads such as the air conditioner(s) running, you can cause an arc over in the transfer switch and this can weld the relay contacts so they can not transfer.
There are other ways the switch can fail as well.
Home is where I park it!
