I rent an apartment with 2 circuit breakers: - 15-amp

Customer Question

I rent an apartment with 2 circuit breakers: - 15-amp for all lights. - 20-amp for everything else, including a toaster oven. When I turn on several lights and then the toaster oven, it trips the 15A circuit-breaker. **The main breaker does not trip, and
the oven continues working.** If I were using too much power, I would expect the oven to trip the main 20A breaker rather than the lights. It seems like there's some sort of interference between the two breakers. Some more information: - This is an old building
(80+ years), before separate 20A circuits were required for kitchen appliances. It's not technically up-to-code, but is grandfathered in so the landlord is not required to fix it. - The circuit breaker looks to be many years or even decades old, though I don't
know precisely how old. So the questions: - What's causing this? - Can it be easily fixed (say, by replacing the breaker)? - Would this typically violate electrical code, compelling the landlord to fix it?

The landlord is usually responsible for electrical repairs unless your lease states otherwise. A non professional should not make repairs theirself.

If you are sure you are plugged into the 20amp circuit but tripping the 15 amp breaker something is definitely wrong.

You should ask your landlord to correct this problem. Being grandfathered " does not exclude repairs.
