3.5 Electrical Loads
When operating AC powered devices through your boat’s AC electrical
system, be aware that each device exerts a “load” on the system. This
load is equal to the amount of current (amps) that the device draws from
the AC electrical system. The AC electrical system, like your house’s
electrical system, has a maximum total load that it can handle. Each line
circuit has an electrical load capacity of 30 amps.
If the total load on the circuit exceeds the circuit’s capacity, the breaker
for that circuit trips. This means that the devices operating from the
circuit are drawing too much current.
Do not overload the electrical circuits. If an excessive load trips a circuit
breaker, turn off all devices connected to the circuit, then switch the
breaker back “ON.”
A list of common AC powered devices and the approximate maximum
current that they draw when operating is shown below. If you use an AC
powered device that has an electric motor, such as a vacuum cleaner or
electric drill, the device should have a “motor load plate” mounted on it.
This plate lists the current that the device draws while operating.

As the chart indicates, appliances that use a motor or a heating element
draw relatively large amounts of current. Therefore, be especially careful
when using curling irons, toasters, coffee makers, hair dryers, food
mixers or similar types of AC powered devices. Do not use too many of
these types of devices at the same time.
