The answer to 'junction box tripping breaker' is that a tripped breaker in a junction box is often caused by an electrical overload or short circuit. This can happen when too many devices or appliances are connected to the circuit, or if there is a problem with the wiring or connections inside the junction box.
Some common symptoms include the breaker tripping repeatedly, flickering or dimming lights, or burning smells coming from the junction box. To troubleshoot, you'll want to check for any loose, damaged, or overloaded connections, and make sure the breaker is properly sized for the circuit. If you're not comfortable working with electrical systems, it's best to call a licensed electrician to diagnose and resolve the issue safely.
