Stacker Trailer 30 Amp 120 Volt Outlet
This article provides basic operation instructions for a
Stacker Trailer 30 Amp 120 Volt Outlet. The optional
stacker trailer outlet is normally found in the electrical
cord compartment. The outlet power is on a 30 Amp
breaker in the main electrical box and will have power
available when the coach is connected to shore power
or operating via the generator. If no power is available,
check the "Trailer" breaker in the main panel, and reset
if necessary. If the coach is operating via the generator,
also check the breaker located on the generator.

Battery Basics
Introduction
As with anything technical, greater knowledge of the
basics may help you increase performance, reliability,
and longevity, as well as prevent future problems with
your batteries. This article will provide information
regarding your coach batteries; however, this is only one
aspect of your coach's electrical system. To learn more
about your batteries' role within the system, please refer
to the 12 Volt Electrical article.

Required Amps
You can look at at your electrical appliances, find the label
14.0 to 16.0 Amps
that contains amperage or wattage ratings and calculate
9.0 to 18.0 Amps
exact usage by using the formulas below.
11 to 17 Amps
•
8.5 to 12.0 Amps
•
2.7 to 6.4 Amps
•
11.3 to 14.2 Amps
16.0 Amps
EXAMPLE
1.0 to 3.0 amps
Most products requiring electricity provide how many
11.3 Amps amps or watts it typically utilizes. If your electric hot water
heater is always in use (~12.5 amps), and you start your air
11.7 to 12.5 Amps
conditioner (~15.0 Amps) and put on a pot of co ee (~9.0
6.0 Amps
amps) and make some toast (~8.0 amps) while watching
4.0 Amps
TV (~ 2.0 amps), you have far exceeded the 30 amp
6.4 Amps
service, resulting in a tripped breaker.
12.5 Amps
Many people don't take into consideration how much
9.0 Amps
power may be used by the inverters charging circuits
10.0 Amps
mostly because they are working automatically in the
0.8 Amps
background. 50 amp service has two 50 amp power legs,
8.0 Amps
providing a total service of 100 amps.
10.0 Amps
10.0 Amps
Commercial lead acid batteries have been used for
over 150 years. The same chemical principal used to
store energy now was also used many generations
ago. Present day chassis battery power requirements
are tremendous, considering today's vehicles and all
of the electrical devices that must be supplied. All of
these electronics require a reliable power source, and
poor battery condition may lead to expensive electronic
component failure. A battery is like a piggy bank - it
stores energy, but cannot produce it. If you continue to
withdraw without making any deposits, you will soon
have nothing left.

Amps x Volts = Watts
