Generac Power Systems Transfer Switches and Accessories Product Catalog page 3

Whole-House Protection
Generac offers air-cooled and liquid-cooled generators that can supply up to
whole-house protection. in conjunction with a transfer switch, this application
completes your power solution package (see page 8 for options).
to accurately size liquid-cooled generators, a licensed electrician should apply
an amp meter to the circuits and appliances to determine the load requirement
for back up.
