For several years my lights have been dimming ,pulsing...not blinking but where you have to stare to see if its really doing it. Its in all rooms at times, like there is a huge draw somewhere in the service line. I have had Master electricians check it, couldn’t find it, wouldn’t charge me..and suspected the electric company Transformer on the service pole.
The Elec. Co. have found no leakage, and a few bare spots on wire to my Entrance meter box. They repaired but in 4 visits could not locate a problem that would cause this. We thought we found it several times, like a loose neutral, grounding or ground wire. Fixed or repaired with no difference. The main breaker on the service entrance pole was 50 years old and rusted. Mice and ground was not attached to anything anymore! Thought that was it for sure! Nope. Replaced the box and meter all circuits do it at times you can see it in lights.
Am I right in concluding its before the house panel? Most guess that when the transformer blows and NYSEG replaces it my problem will stop, NYSEG says it won’t replace what isn’t obviously bad even though its over 40 years old.
