When plugged into 50 amp service, L1 and L2 each get a separate 50 amps, so there is actually a total of
100 amps available, or 12,000 watts of power. When plugged into 30 amp service, only 3,600 watts are
available.
Each of your electric appliances consumes a certain amount of power (watts) at startup and usually less
when running. This is usually expressed in amps. For example, an air conditioner might take 15 amps at
startup, and 13 amps when continuously running the compressor.
When running three air conditioners at the same time, along with other devices, such as the
Microwave/Convection Oven, the Induction Cooktop, the Washer and Dryer, Water Heater, along with
“hidden” loads like the Power Converter that supplies 12V DC power to the lights and batteries, you can
exceed the power available from a 50 amp pedestal. The Power Control System will temporarily turn off
power to some devices to manage total power consumption.
Reading the Precision Circuits Display
Each line on the display shows the name of the load (ex: Water Heater), whether that load is currently
being supplied power by the Precision Circuits Controller (ON or OFF), and the number of amps the load
was using the
last time the Controller turned that load OFF
.
The refrigerator status in the picture above shows that it is currently ON. The last time it was shut OFF,
it was using 7 amps.
