💡 What is a double pole circuit breaker used for and how does a thermal-magnetic common-trip breaker protect a home electrical panel? A double pole breaker ties two hot legs together so both disconnect at once for safety and 240V loads. - Provides simultaneous disconnect for 240V appliances and large loads - Common-trip thermal-magnetic design detects overloads and short circuits for fast protection - Plug-in Q-Line mount fits standard load centers for quick panel replacement and serviceability - Helps meet code for shared neutral circuits and reduces risk of backfeed and dangerous faults
