Breaker randomly trips. Help!!!

All,
I have a home that's 5 years old, the issue I'm having is that a breaker ( controls foyer chandelier, and upstairs hallway light) keeps getting tripped for some unknown reason. The builder decided to put 4 separate switches to control the upstairs hallway light, I'm wondering could that he the reason why the breaker trips? Any help is greatly appreciated.

Welcome to the forums.

Having many switches controlling a light won't cause the breaker to trip. You mentioned two lights that go dead when that breaker trips. Is there anything else that goes dead ?

Is that a regular type circuit breaker or does it have a push test button on it ?

Thanks for the quick reply! Hm nothing else that I know of goes dead. I took a look at the breaker, it has a small white vertical rectangular button on it, I'm assuming that's the button?

A small white button on the breaker tells us it's a newer style arc fault breaker. These breakers trip with any type of fault be it a quick short or even a circuit fault where the neutral touches ground.

Arc fault problems are not always easy to find. It could be neutral touching ground at one of the lights or switches. Even a staple driven too hard into a romex cable can cause problems.

Does it seem to only trip when using one particular light or has it tripped and you find out when the light doesn't work. It could also trip the second you turn the light on. It will take some investigating to narrow down the problem.

I believe it happens on 2 of the four switches are used. I'll try to narrow it down further.

Thanks

It could possibly be a loose bulb mimicking an arc.

I have also seen one trip when a ham radio operator keyed his transmitter inside the house.
