Performed an inspection today on a home built in 2001. Typical electrical service panels (two), however, when I was measuring voltage at the circuit breakers, I noticed a voltage difference of approximately 10 VAC between the two legs of the incoming power. When measured directly at the incoming lines, one leg measured approximately 113 VAC while the other was closer to 123 VAC. In addition, the interior lights flickered slightly when electrical demands (i.e. A/C system start-up, operating the trash compactor) were placed on the system. I typically only see 1-2 VAC difference between the two legs when measuring. Any ideas on why such a difference in the voltage…and comments on what (if any) deficiency?
