receive power. This cord places 120-volt power into your breaker
distribution center, as built into your coach.
Energy will enter through the main breaker and is
distributed through circuit breakers to the wall
receptacles and appliances. This power cord will
be approximately 26 to 28 feet in length. Each
cord has the correct gauge of wire to carry the
correct voltage to coach.
In some hook-ups the power cord may not be
long enough and extension cords are required.
Always use a cord with the gauge of wire equal
to or greater than the power cord. Should you
use a cord with a smaller wire gauge,
overheating, loss of amperage, and possible
melting could occur.
DO NOT leave any unused portion of an
extension cord in a “coil” as it may overheat,
short-circuit wires and potentially destroy your
extension cord.
Circuit Breakers and Box
—120-volt
On a 30 amp system, a maximum of six distribution circuits are permitted.
All breakers are sized according to power needs on each line.
The following generic drawing shows the circuit breaker alignment with
number one being the main breaker on all floor plans. Depending on the
size, floor plan and options of your coach, circuit three through six will
vary and possibly not all circuits will be used. Number two is the 20 amp
air conditioner circuit beside 30 amp main.
An owner must realize and understand that a coach has a total of 30 amp
service available to be used. Conserving and choosing which appliance
has priority in consumption needs to be part of the planning.
A 50 amp service is a 240-volt hook-up. There is no appliance
or other component requiring 240-volts in this coach. For
more information, see the section later in this chapter: 50 amp
(optional).
Never use a “cheater” plug or extension cord, which breaks
the continuity of the ground circuit to the grounding pin.
