HEARTLAND RECREATIONAL VEHICLES, LLC
provides one of two different power systems. Your
coach has either the 30-amp or the 50-amp service
detailed below.
30-amp/110-Volt Service
If you have 30-amp service, your power cord will look
like this typical 30-amp power cord, which pulls out of
the unit.
30-amp service is also 110-volt service, but it is capable
of running up to 30-amps of draw. 30-amp service has
only one prong that carries 110 volts of AC power.
50-Amp/110-Volt Service
If you have 50-amp service, your power cord will look like
this typical 50-amp power cord, which attaches to the unit.
50-amp service is also 110-volt service, but it is capable
of running up 50-amps of load. Some people believe
that 50-amp service is the same as having 220-volts of
AC power. Yes, 50-amps of service does have 220-volts,
but only 110-volts is capable of being supplied to any
part of your system at any given time. A unique, four-
pronged power cord identifies 50-amp service, as two of
the four prongs each carry 110-volts of AC power. Each
of the 110-volt lines in a 50-amp cord supplies power to
a designated part of your RV. In doing this, when 110-
volt AC powered components are installed they can be
put on separate power feeds according to how much
amperage they draw. One example of this method
consists of installing two air conditioners for use at the
same time. Each one is powered by a different power
supply feed with the 50-amp power cord; therefore they
can both be used simultaneously.
WARNING
MAKE SURE YOUR POWER SUPPLY (SHORELINE HOOKUP) IS
PROPERLY GROUNDED! IF YOUR POWER SUPPLY TO THE TRAILER IS
NOT GROUNDED YOU WILL EXPERIENCE A DANGEROUS SHOCK WHEN
STANDING ON THE GROUND AND TOUCHING A METAL PORTION OF
YOUR TRAILER! USE A CONTINUITY TESTER TO ENSURE PROPER
POWER SUPPLY!
CAUTION
DO NOT USE AN EXTENSION CORD WTH A CURRENT RATING LESS
THAN THE AMPERAGE YOUR RV REQUIRES. EXTRA EXTENSION CORDS
REDUCE THE AMPERAGE AND VOLTAGE BEING SUPPLIED TO THE RV
AND MAY CAUSE DAMAGE TO ELECTRICAL COMPONENTS, INCLUDING
THE SHORELINE CORD.
Note
IF YOU TRAVEL TO AN RV PARK THAT DOES NOT
OFFER THE APPROPRIATE AMP SERVICE YOUR
COACH REQUIRES, YOU WILL HAVE TO USE AN
ADAPTER TO HOOK UP TO SHORE POWER. USE OF
AN ADAPTER IS NOT RECOMMENDED, BUT MAY
NOT BE AVOIDABLE. WHEN USING AN ADAPTER,
REMEMBER THAT YOUR COACH WILL NOT HAVE
SUFFICIENT POWER TO RUN AS MANY OPTIONS
AS WITH FULL-AMP SERVICE. YOU MAY BE ABLE
TO RUN BOTH YOUR AIR CONDITIONERS FOR
A LIMITED TIME: HOWEVER, THIS WILL CAUSE
DAMAGE TO BOTH YOUR AC UNITS AS WELL AS
OTHER COMPONENTS BY OPERATING THEM WITH
INSUFFICIENT POWER.
