Back at the electrical panel voltage between L1 and L2 would not read with my digital meter. But L1 to ground was low 80 volts and L2 to
ground was 120 volts to ground/neutral. Please not that the neutral is bonded to a copper water line and that water line goes to the
town water sytem.
My thoughts are the old underground my had been hit by some digging, and that someone splice the L1 or possible all three cables.
But the splice that underground made in L1 conductor is going bad. But really want to cross all T's and dote all i's. before digging.
Also know one I ask can remember who installed the service. This 3-conductor wire underground service comes off a circuit breaker
disconnect, with is bolted to the load side of the Meter Socket. Thanks for your reply danpik.
Does L2 remaIn solid all the time ?
Whilst only L1 varies ?
If so you probably have either a loose connection,
Or too much load on L1 as compared to L2
I would ask POCO to check the incoming service,
for bad loose /connections.
This is about all you can do without calling an electricain in.
