2012 Trip
Load shed example, if average current
demand exceeds 24 Amps when hooked to a
30 Amp service, the system will automatically
shed load Number 1 (refrigerator) to keep
average current demand below 80% (24
Amps) of the 30 Amp shore service to avoid
the possibility of overloading the shore
power breaker. If shedding load number 1 is
insufficient to avoid tripping the shore power
breaker, the system will shed load 2 (water
heater) and so on until power demand in total
is within safe operating limits. Indication a
load has been shed is when the load is no
longer illuminated in the Status column.
NOTE:
20 amp shore service mode is not
automatically detected and the
operator must manually set 20 Amp
mode when connected to 20 amp shore
power.
Loads shed in order of priority:
1. Refrigerator
2. Water Heater
3. A/C - 2 (Bedroom)
4. A/C - 1 (Living Room)
Power Share and Reduced Charging:
Depending on operating conditions,
amperage of shore power and battery state
of charge, the system may attempt to reduce
battery charging as a way to conserve AC
power during peak demand or if batteries
are of sufficient charge, the system will
automatically enable the inverter to help
supply extra power during peak demand
periods.
Circuit Breakers
The internal configuration of
the circuit breaker is designed to
trip when excess current causes
the breaker to heat up. The trip
action of the circuit breaker
can occur within milliseconds.
Breakers are designed to operate
at a continuous load of 80% of the
breaker’s rated capacity.
For example:
A breaker with
a 20 Amp rating will operate a
continuous 16 amp load. This
design leaves a small amount
of working capacity within the
breaker.
When an inductive load is
applied, such as when an electric
motor turns on, the motor starts
to spin and current consumption
may momentarily exceed the
rated capacity of the breaker.
As the electric motor comes up
to operating speed, the electric
motor’s current consumption will
decrease.
The AC current load then falls back into the
breaker’s rated 80% set point. This electric
principle should be kept in mind when using
anything other than 50 Amp shore service and
using appliances with electric motors, such as
air conditioners.
When using outlets, care should be considered
when applying loads such as electric motors,
heaters, coffee makers, toasters, hair dryers
or other large current consuming loads. The
current rating is usually stated on most electrical
items. The current rating will either be rated in
amps or watts.
Current ratings stated on electrical items
will change slightly with voltage fluctuations.
As voltage increases, current consumption
decreases. As voltage decreases, current
consumption increases. This may explain why
in some instances items operated at borderline
voltage to current tolerances may seem fine in
one location but problematic in another.
NOTE:
To calculate watts to Amps divide the
watt figure by the voltage from which
the item operates from. For example:
The electrical item is rated at 1370 watts.
Divide that by the operating voltage of
115 Volts AC which equals 11.913 Amps.
Use this formula to calculate the amount
of load and compare to the available
power supply.
GFCI Breakers & Outlets
A
Ground Fault Circuit Interrupter
(GFCI)
can be found in two different types
of applications. One type is incorporated in a
breaker used in 120 Volt AC breaker panels;
the other is incorporated in an outlet. The
GFCI, whether it is a breaker or an outlet,
offers two types of protection. One type of
protection is from over-current or shorts to
guard against hazardous ground fault currents
that can result in injury or death. Ground
fault currents are currents that flow from the
“hot” or power terminal through a person to
the ground.
For example:
touching a faulty
appliance while making contact with an
electrical ground such as a water fixture or the
earth.
