DC Systems - 12 Volt
A majority of lighting and appliances are designed to operate from 12 Volt DC (direct current) power, which
is why the battery plays an important role in the function of the recreational vehicle. Keep the 12 Volt system in
working order. These systems, with incorporated electronics, are voltage sensitive. Some items can be damaged if
DC voltage is not maintained within the designed specifications. Become familiar with the 12 Volt system panel
and the items they operate.

The standard power requirement for the recreational vehicle is 30 Amp 120 AC Volt single phase. However,
if equipped, the requirement may be the optional 50 Amp 120/240 Volt single phase. Certain models cannot be
wired for 50 Amps. Electrical adapters will be required when using the lower amp shore power service.
CAUTION:
Avoid flash damage to the electrical system contacts. Before hooking up to shore power
make sure all the appliances are off.
WARNING:
Keep fingers away from metal contacts of the shore plug end. Avoid standing in water when
making electrical connections. Serious electrical shock and personal injury can occur. To
avoid the risk of an electrical shock, turn the circuit breaker off for the power supply outlet
before making the shore power connection.
Plugging in the Shore Cord:
• Locate the shore power cord.
• If using lower Amp service, other than what the recreational vehicle is rated, install the proper electrical
adapters to the cord.
• Always turn off shore power breaker to power supply outlet before connecting or disconnecting shore cord
to prevent an accidental shock and flashing of electrical contacts.
• Make the connection to the outlet and turn the shore power breaker on.
Power Supply:
Different amperage supplies vary greatly in the amount of
available current.
• The continuous amount of current through a breaker or fuse is only 80% of
its rated capacity.
• 50 Amp 240 Volt AC shore power service consists of two power supply
conductors (120 volts AC each), a neutral and a safety ground. The 50 Amp
breaker limits each power supply conductor to no more than a short-term
maximum of 50 Amps for each conductor. The 50 Amp 240 Volt service
actually provides 80 continuous amps.
• Use care when hooked to anything less than 50 Amp shore service. Shore
power service less than 50 Amps consists of one power supply conductor,
a neutral and a safety ground. 30 Amp shore service is limited to 24
continuous Amps. 20 Amp shore service is limited to 16 continuous Amps.
