Total Running Load
Largest Estimated Simultaneous Running Load (LESRL)
Largest Startup Wattage (LSW)
Minimum Backup Power Needed = LESRL + LSW
NOTE
Inductive loads such as air conditioners, clothes dryers or pumps have high Inrush current when
starting. This may trip the relay modules because of overload. Ensure the circuit is sized appropriately
for the intended load.
Once you have determined the load circuits that you want to back up, fill out the table below. The
numbering arrangement is the same as your SHP.
