Breakers tripping other breakers

[DanielF]

Asked my electrician this question but he never experienced anything like it and did not have any real suggestions or tests.

My daughter bought a new condo. We found out that when you switch one breaker off (I'll call it Breaker1) and then turn it back on it trips another breaker (Breaker2) . Turning Breaker2 off then on does not trip off Breaker1. Seems that Breaker1 only affects Breaker2.

Just as a note these breakers are not near each other in the box. Also, these are breakers that control lights and outlets. Not sure why this would happen?

TIA.

Are they GFCI breakers, or simple over-current ones?

My son had this problem as well.

It turned out somebody had took a live feed from the downstairs lighting circuit to the bottom of staircase switch

Then upstairs lighting circuit to the light over stairs which was 2 way to switch at bottom of stairs with a mish mash of 1mm cables.

I'm still trying to fathom out how somebody actually got this to work.

But it did what you are describing so might be worth getting an electrician to have a look at it!

Turning on one breaker should not effect another breaker. Since you are not an electrician I suggest that you have your electrician to turn off the main breaker and kill all power. Then he can test continuity between the 2 phases and with all breakers turned on except the main your electrician should not have continuity between the 2 phases. Since the condo is brand new and should be up to code according to the NEC. That’s a strange problem,

Thanks for the feedback. The condo is 32 years old.

I believe you are correct on ultimately there needs to be some sort of testing done.
