Electrical Panel Getting Warm but the Breaker Stays On? Here's Why

Why can an electrical panel get warm while the breaker stays on? A breaker responds to overcurrent, but it does not measure the temperature of every connection. In this video, we explain how resistance at a connection can create a local hot spot, why an RCD may not trip, and how to interpret thermal images. We also look at warning signs and what a qualified electrician should check.
