Electrical Question from Joe about New Light Fixtures Tripping The Circuit Breaker
Background: Joe, a Homeowner from Seekonk, MA
Question: I just replaced 2 of my old outside wall mounted lights with 2 new ones I hooked them up Identical to the old ones but every time I turn on the switch it trips the circuit breaker. Can you please help me and give me some tips as to why this is happening thanks Joe

Dave’s Reply:
Thanks for your electrical question Joe. Remove each fixture and look for a pinched wire. Free the wire and inspect for damage. If the wire has caused a burnt area then you may need to cut off the damaged area and remake the connection. If the wire was a direct short then most likely there is no burnt wire damage however you will need to wrap the wire with electrical tape over the pinched area. Position the wire into a clear area and remount the light fixture. If this is not the problem then one of the fixtures may have a wiring problem from the factory. Discover which fixture has the problem by removing one at a time and re-energizing the circuit breaker.
