Hi I am trying to trace back an old line that was a dedicated line that powered my old oil fired hot water heater. I had a new elctric hot water heater installed by a professional who added a new 30amp breaker and box. The kill switch to the old hot water heater is still intact in the hallway. I checked to see if it was live AND YES IT IS. BUT MY VOLTMETYER ONLY READS 62VOLTS. WHATS UP WITH THAT ? - HALF OF 220 I KNOW. I C AN'T TRACE IT BACK TO ANY OF THE BRERAKERS IN THE PANEL. ANY SUGGESTIONS ON HOW I CAN LOCATE WHERE THE POWER IS COMING FROM? WHAT DOES THE 62 VOLT READING TELL US. THANKS
