why does my light switch trip the breaker

Going outside to mess with your tripped circuit breaker can be overwhelming if you don t know what or why it happened. If you re not an electrician we d suggest you contact one. Something may be seriously wrong with some electrical wires as to its overloading of current. A circuit breaker trips or shuts off the electrical flow to protect the circuit from overheating and causing damage--
even possibly an electrical fire. We don t want to alarm you, but it s better to be safe than have you or a loved one hurt or in danger. Before you go and flip the switch on again, take a moment to determine what the root cause is of the tripping of the circuit breaker. The circuit overloading is the most common reason your circuit breaker is tripping. That means you re running too many heavy power consuming devices at the same time on the same circuit. For example, if you have a 15 amp circuit with 20 amps worth of electricity running through that same circuit because your hair dryer, TV and air conditioner were all on at the same time, then the circuit breaker will trip to prevent overheating.


Redistribute the power-heavy devices on the overloaded circuit to another general purpose circuit. Turn off some devices on the circuit to reduce the electrical load. UPDATE: Another cause of an overloaded circuit is an overheating appliance. It pulls in more amps than normal, causing the circuit to overload. An overheating central air conditioner is notorious for this during the summer. The next possible (and more dangerous) cause is a short circuit. A short circuit happens when a hot wire (black) touches another hot wire or touches a neutral wire (white) in one of your outlets. When these two wires touch, a large number of current flows, creating more heat than the circuit can handle, so it shuts off.


You can tell if there was a short circuit by checking your outlets and plugs for the smell of burning, or brown/black discoloration. These wires can cross for multiple reasons, but it could be as simple as a loose connection or improper wiring. Similar to a short circuit. A ground fault happens when a hot wire (black) touches the ground wire (bare copper) on the side of a metal outlet box which is connected to the ground wire. Just like a short circuit, you need to see if anything looks out of the ordinary with your outlets.

Safety first, always!!! If you re not sure which of the problems listed above is causing your circuit breaker to trip, and want on-site help with your circuit breakers or to check your wiring,. I have been living in my house for 8 years now, and there has always been a mystery switch and outlet (both located on the same wall). My wife has rearranged the room, and now we will need to use the mystery switch and outlet. The switch is wired and has power, but it does not go to anything. In order to determine which circuit it was on, I removed the switch and wired an outlet to it. I plugged a ground fault detector and it read Hot/Grnd Reversed. So I did what anyone else would do (i think) and switched the wires around. Same reading. So I found a junction box in the basement, where I thought I would have found where my issue was or where the switch is wired to.


NOPE. Here I found a white wire colored black attached to a black wire, so I change them around thinking this was my issue - nope same reading. There are 8 wires going into the junction box, so I undid all the wires and put them all back together (trying to find the wire for the switch) no luck. The light switch in the room where the junction box is trips my breaker (the lights turn on when the light switch is off and trips the breaker when I switch the lights on) - yes this switch is wired to that junction box. I checked to see if I may have swapped a wire in the junction box but all neutrals are together as well as all the hots. Why is this happening? Sorry for this being so long. I am looking forward to any insight or assistance you can provide.
