Pictures would be VERY HELPFUL !
Are their any outlets that are NOT connected to your inverter ?
The quick way to install an inverter and still have a SIMPLE bypass is as follows
(it does assume you have access to some of you wiring) :
- Disconnect the wires at shore power plug.
- Connect those wires to a heavy duty 3 wire female plug
- Get a 12/3 extension cord that is long enough to reach from the back side of your shor power plug to where the inverter is mounted.
- Cut the male end off, but leave 2-3'. Connect this to the back side of the shore power plug.
- Make the rest of that cord back into an extension cord by install a new male end. Plug the neww male end into the inverter and leave the female end loose near the pigtail you put on the shore power plug.
To use shore power, plug the pigtail in the the your AC wiring. To use the inverter, plug the inverter, plug your AC power into the the extension cord from the inverter.
The other even simpler solution is, to have the extension cord from the inverter exit the trailer near the shore power and just PLUG IT IN. Of course you may not want to go outside in the morning in you pajamas to plug it in to make a cup of coffee !
