WebA thermal-magnetic OCPD is an OCPD that reacts to the heat created by the copper loss (I2R) when current passes through a conductor. Copper loss is caused by the resistance of the conductor to a current passing through it. This loss is expressed as heat. The higher the current flow through a conductor, the more heat is created. WebJul 30, 2024 · They have nothing to do with each other. Lightning already traveled thousands of feet through the air. The little air gap in a circuit breaker isn't going to do anything to stop the lightning even if it were fast enough, which its not. Series breakers don't increase protection (in that protection doesn't increase by stacking breakers).
