50 Amp (Optional on larger coaches)
On some larger coaches, with more appliances that require 120-volt,
more AC power is desired by owners. Availability of 50 amp service is
the best and only method, providing you have 50 amps of incoming
power.
For this application, a larger circuit breaker box is required as there are
two separate banks of 120-volt AC power on the positive position. Each
positive bank receives a 120-
volt wire marked “X” or “Y” plus a white
neutral wire and green/bare ground to complete circuitry.
Actually these two positive wires added together are 240-volt AC service
yet serve two separate banks as the external sticker indicates. A 50 amp
main breaker will distribute current to separate banks, verifying 240-volts
are present. There are no 240-volt appliances in this coach.
If use of a “reducing” adapter or pigtail is needed because 50 amp four
prong service is not available, several things must be remembered.
1.
A “reducing” adapter prevents you from using 50 amp service as
designed, permitting only 30 amps or less to enter your coach.
2. Should you choose to plug your camper power cord into a
building receptacle, BE SURE it does NOT have (2) two positive
wires which will be 240-volt AC Power.
DO NOT connect 240-volt direct power to the coach through a
reducing adapter. By doing so, “positive” power will be sent
through neutral/white wire damaging appliances.
