Circuit Breaker Protection; Ground Fault Circuit Interrupter (Gfci) - Airstream TOMMY BAHAMA INTERSTATE 19 2024 Owner's Manual

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.

Ground Fault Circuit Interrupter (GFCI)

All outlets/receptacles on your Touring Coach are
GFCI protected� The GFCI breaker provides reliable
overload and short-circuit protection� GFCI breakers
protect against ground faults and provide additional
safety to the occupants of the touring coach on all
outlets/receptacles� A ground fault occurs when current
travels along an unintended path to ground, possibly
through water or a person, which may result in an
electric shock� The GFCI compares the amount of
current going to and returning from the device plugged
into the circuit's outlet/receptacle� When the amount
of current going to the device differs from the amount
returning, the GFCI interrupts the current within a
fraction of a second, removing power from the circuit,
and protecting the user�
Each GFCI circuit breaker is calibrated to trip with a
ground current of 5 mA or more� Since most people
can feel as little as 2 mA, a shock may be felt� The
shock should be of such a short duration that the
effects would be reduced, less than what would
normally be a dangerous level� However, persons with
acute heart problems or other conditions that can make
a person particularly susceptible to electric shock may
still be seriously injured�
While the GFCI circuit breaker affords a high degree
of protection, there is no substitute for knowing that
electricity can be dangerous when carelessly handled
or used without reasonable caution�
The system incorporates GFCI breakers that
implement an auto-self-test functionality� When turned
off, these breakers require external AC power to be
present before they can be turned back on� If power is
present, and the breaker refuses to stay on, consult an
electrician or certified RV technician.
The GFCI circuit breaker will NOT reduce shock
hazard if contact is made between a HOT load wire
and a neutral wire or two HOT load wires. GFCI
circuit breakers provide protection only to the
circuit to which it is connected. It does NOT protect
any other circuit.
