120-Volt A/C System
Power Cord 30 amp or 50 amp
All units have 30 amp or 50 amp power cords that are detachable from
the inlet connection. The cords are to be stored inside of the unit when
not in use. This cord places 120-volt power into your main breaker
distribution center, as built into your coach.
Power 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 gage of wire to carry the correct voltage to
the coach.
In some hookups, 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
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 (following page) shows the circuit breaker
alignment with number one being the main breaker on all floor plans.
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.
Don’t forget, loose items such as toasters, coffee pots, etc., also consume
power. Include these in your planning.
DO NOT replace breakers or fuses with any that are rated at a
higher amperage. Over fusing may cause a fire by
overheating the wire.
