When figuring the branch circuit size of a Cooler unit, do you add the motor circuit amps with the defrost circuit amps? On the nameplate it has them separate, but no total amperage or maximum fuse size. It only has the maximum fuse size for the motor circuit. The motor circuit is 6.88 amps with max. fuse size as 20 amps. The defrost circuit has 26.09 min. circuit amps with no max fuse size. Thanks.
