went on a service call today HO lost half his lights, plugs & all his 240volt equipment, i get there & start checking voltages at the panel, phase A to G & N 95 volts (no load with load 50v), phase B to G & N 120v, (load & no load) phase A-B 215v. then i went to the meter main panel phase A to G 120v phase B to g 120v,phase A -B 240v. this a newer service, with 100' of direct burial cable between panel & meter main panel. the only thing i can think of is a bad cable. meggered the cable got low reading on all 3 wires ( i don't trust my old megger) looking for a second option before redigging the trench
