Circuit Breaker Tripping

20251220: Breaker #8 is tripping again. Appliance tech was installing main kitchen fan and could not get the fan running due to electrical wiring issue that requires electrician to followup. He believes the breaker #8 is the one that powers the fan.

20251212: Breaker #8 is no longer tripping. Uncertain if this has to do with the plumber’s complaint about the wiring problem and/or appliance technicians sorting out the power for the appliances they have installed so far.
