A friend asked me to install a small 4 circuit transfer
switch little combo panel next to his sub-panel in his laundry room. The goal is to provide some lighting, a few outlets and keep the refrigerator going during a power outage. He has a typical 5000 watt portable generator with twist-lock and u-ground receptacles. How much circuit tracing and load calculating is typical in the planning of a small system like this. The homeowner knows he has limited power to only run the refer and a few lights.
