Summer time is coming, touch your breakers!

When your AC starts going it may be time to survey your electrical panel for hot spots.  Just put your fingers on the body (not the switch) of each breaker and see if any of them are actually hot.

CAFCI breakers run 20 degrees warmer than ambient, that's normal, but nothing should feel hot even when all your devices are running.  Your panel too should feel ambient.

PS - If you have older AFCI breakers that buzz, the new CAFCIs are better and tend to be quieter.
