Electrical System Overview
Power Center
The Power Center is a self-contained 120 Volt AC
(VAC) power distribution center utilized in recreational
vehicles� It houses the coach’s circuit breakers
and fuses� Its primary function is to provide circuit
protection for all the 120 VAC loads in the touring
coach and is central to the overall electrical system�
It distributes 120 VAC power to the appliances� It also
distributes 120 VAC to the converter, which converts
120 VAC to 12 Volt DC (12V) to power 12V systems�
The Power Center distributes incoming power from
two sources: Shoreline power when connected to an
external 120 VAC power supply (city power) and the
Volta Power System’s Flex Pack (lithium-ion battery
pack) via the 58V DC to 120 VAC AC inverter; see
Electrical System Operation on page 5-13�
The Power Center is under the roadside bench seat�
Open the decorative door to access 12V fuses and 120
VAC breakers�
WARNING
The power center is a centralized power switching,
fusing, and distribution center. The potential
of lethal electrical shock is present in this box.
Inadvertent shorts at this box could result in
damage and/or injury. All servicing of this box
should be done by a qualified Service Technician.
Circuit Breaker Protection
Standard residential-style (resettable) circuit breakers
provide circuit protection for all 120 VAC loads�
Airstream has installed breakers per RVIA (NEC) listing
requirements for the touring coach�
The 30 amp main breaker feeds individual branch
breakers� The branch-breakers protect individual loads,
which are identifiable by the affixed labels. Shutting off
the main breaker will remove power to all branch loads
(except for outlets/receptacles on the inverter circuit
when the inverter is enabled, see GFCI below)�
A circuit breaker’s ON/OFF switch function operates
like a light switch: up is ON, and down is OFF� If an
overload or short occurs, the breaker will snap to the
OFF position to protect the connected circuit� As a
result, any device running on the circuit will lose power�
Before attempting to reset the breaker, consider the
cause� If a connected device is faulty or uses a higher
amperage than the circuit breaker’s capacity, turn it off
before resetting the breaker�
Before resetting the breaker, you need external AC
power going to the breaker box� Firmly push the
breaker switch to the OFF position and back to the ON
position� If the breaker snaps back to the OFF position
while resetting, a fault condition still exists and should
be serviced by a qualified Service Technician. Suppose
the breaker stays ON but snaps back OFF after turning
on a possibly faulty appliance� In that case, a fault
condition may exist in that appliance that will require
service by a qualified Technician.
