The electrical connection utilized by
pop-up campers is a 110v 30a RV style plug. We have often talked
about putting in a 30 amp breaker and RV style outlet for the camper at
the house. The A/C in your unit draws (uses) close to 15 amps when it
starts, and around 9 - 10 amps running. Add to that any other electrical
devices in your camper and you quickly see why a 30 amp electric supply
is needed. Most standard household plugs only supply 15 amps, so
using a common adaptor to allow the 30 amp RV plug to be inserted into a
standard household 15 amp outlet may be quickly overloaded. While this adaptor may be safe
to use in limited situations when you closely monitor what devices are
being powered, I think the installation of a 30 amp RV style outlet.
It was only when our Air Conditioning went out at
the house that we "needed" the camper to use as an "air
The service plug for the camper (the big black wire that comes out the
back/side) carries 30 amps, 20 of which are usually used by the A/C and
10 for other devices (like the 12v converter)
To use the A/C at the house you need to do one of two things:
1. Install a 20 amp plug close to where you park the camper, and get a
real 20 amp extension cord (the shorter the better). You would plug the
cord that hangs down from the ceiling of your camper into this cord, and
it would only supply the A/C.
2. Install a 30 amp RV plug plug close to where you park the camper, and
into this you can plug the 30 amp RV cord.
We chose to do #2. After a trip to Home Depot (for the new
breaker, box, cover plate and wire) and a trip to a local RV dealer (the
30a plug, neither Home Depot or a local electrical supply house carried
them) I had all the parts.
If you are not
comfortable working with electric, hire someone to do this!!!!!!!
Open the breaker panel and install 30 amp breaker.
This will be wired to the 30a, 110v RV style plug. It was easy for
me as the panel is in the garage, right by the overhead door. The
new 30a plug could be installed right below the breaker panel.
just because you have a space to plug an additional breaker in
does not mean the panel has sufficient service to handle the load.
OK, I admit it was late at night when I did
this. I went back and turned it over so that it is now
oriented correctly. I will take a new picture when I get a

angled blades, and the round "common" plug.
This is not to be confused with a 220v plug for a clothes
|If you look at the
cord and plug inside the camper for the A/C you will see one of
the blades on the plug is turned "sideways", which
will only allow it to be plugged into a 20 amp plug. The
corresponding plate (pictured below) will allow a 20a or 15a
plug to be plugged in (notice the "T" shaped socket on
the right side.
Make sure that the electrical service
to the breaker panel will support an additional 30a device being
attached to the panel. Just because you have open spaces, does not
mean you have sufficient service.
Also make sure you use a sufficient sized wire for the distance involved
(#6 - #8 - #10) and
local electrical codes! Again, if you are not sure
what you are doing, hire an electrician!!!!!!!

August, 2002 update:
I have been advised that Lowes now carries the 30a RV
outlet in some of their stores. Information I received was that it
is part number 78748 listed as a "3-wire flush 30a", priced at
$7.37 + tax .
