At a 240 volt residence service with aluminum branch wire with black cable jacket through out entire home. I received a call that had open neutral in two different circuits. When I opened an outlet tested a duplex, phase to neutral 15 volts, Phase to ground 120 volts neutral to ground 240 volts! I then tested phases in service 130 volts to neutral, when neutral was connected to ground in duplex service phase reading 120 volts to neutral. When I connect neutral to ground at duplex and tested phase to neutral 120 volts. I then opened outlets in several rooms and could not find a loose or broken neutral wire. There was some renovation years ago.I have no access to attic. I could use someone give me some insight how to locate open neutral or cross phased wires.? This seems to be a hazardous situation.
