I'm sure i've read about this problem before here on this forum. I went on a service call this morning, to an older home (waterfront property) problem is lights dimming ref, and a/c not working. Open panel, check all connections, check voltage with everything off and read 123v to gnd. on each phase 245v phase to phase, seems ok.
Turn on lights that are reportedly dimm and read 178v phase a to gnd. 69v phase b to gnd. Follow neutral back to p.o.a. there is a small amount of corrosion to the neutral, as it is an aluminum seu cable, in a salt air enviroment but not that bad, cable is 12 years old.
poco was at site night before and said not their problem. They preformed their test when nobody was home, therefore no load on service, home owner turned off main breaker. This is a summer home only used on weekends.
As a side note, house next door is vacant and being renovated , ec installed new service just this week. Could there be something wrong with neighbors new electrical work? as both homes are fed from same x former.
So far i've installed new bugs at p.o.a. and convinced h.o. to change over to copper service entrance cable which i'll do during the week. What else should i be looking for, prior to getting poco back to the house?
Thanks to all who reply. Mark
