Two months ago, the kitchen lights were flickering. I realized the kitchen lights and outlets were connected to a single breaker. I measured the voltage and it spiked from 5v - 120v intermittently. I replaced the breaker (Murray 15A single-pole #MP115) and all was well.
Three days ago, the same kitchen lights started flickering again. The breaker read at 102v - 105v which is well below the expected 120v. I flipped the breaker multiple times and measured voltage and different times of the day, but it was always consistently 102-105v. I replaced the breaker today and all is well once again.
Both breakers that were replaced did not look or smell burnt. Any idea why this happened? Could it just be the breaker I replaced two months ago was also a bad breaker? A friend suggested a current surge through the wires, but my assumption is if there was a current surge, the breaker would have tripped or burnt out instead of having a low voltage reading of 102v-105v.
