While staying at the inlaws for the holidays, I noticed they have a 4-prong plug NEMA 14-30P for a portable generator in the garage. I checked it out and it has a 30amp breaker in the panel that provides power.
I decided I would make up an adaptor that would allow me to connect my 50amp RV cord to the plug and make it possible to run more features inside the RV (AC/Heat Strips, TV's)
I picked up a Power Grip 50-Amp Replacement Female Receptacle,
and a GE Dryer Cord
cut it to about 9" and attached the power grip to the other end.
Plugged in the GE end into the outlet, plugged in the progressive Surge Guard to make sure the wiring in the wall was good, and plugged the RV cord into Surge Guard.
BOOM! AC in Arkansas in December. Who would have ever thought it would be 80 Degrees the week of Christmas in AR!!
