My camper is rigged for 110V shorepower only. No DC. Below is the diagram I drew to show to an electrician friend of mine to see if I wasn't gonna mess up somethin' or hurt somebody. As you can see I'm not an electrician but from a couple of basic housewiring books I had around the house I came up with this.
Basically I have a box inside the camper that provides three circuits. 2 15amp and one 20 amp. I plug in everything. Most of the receptacles are housed in one cabinet along with the service entrance box. All the lights just plug into these receptacles. Real simple. The microwave and AC also just plug into these receptacles. I do have two outside 20 amp outlets and two 20 amp interior receptacles that are accessible from the interior. Three of the interior flourescent lights have 10 amp receptacles also. So I gots plenty of plug in places.
So behind door number 1
My little service entrance box with all the receptacles and stuff plugged in. This is the way you do it when ya don't know much about whatcher doin'....but it all works....at the same time...no smoke...no sparks....all grounded and no one hurt.
Shore power comes in from underneath through this little entrance box. Da rain can't get to it here. I carry a 50 foot shore power line with two male plugs.
