Need a little help on this one. Just came back from an Inspection where I found a 15AMP double poll breaker had the bottom leg 18 degrees celsius hotter then the top leg. The breaker was not marked but I suspect that it is fore the detached garage. The garage was heated, had a 8 foot pool in it for fish. A hottub was outside and also plugged into the garage. Is there a possibility that the garage is drawing enough power on one leg to over heat but not trip the breaker??
There are also double taps in the panel but did not read high.
