A customer from a row home calls me and tells me that he received a good shock, while in the shower, as he was adjusting the shower head. He also tells me he smells something burning in the basement. I will just state the facts, to keep this as short as possible.
Facts: 1st day
60-volts from soil pipe to cold water pipe.
No-hub fittings on soil pipe are melting and stainless clamps are glowing.
Turn off all breakers, one at a time, still getting voltage.
Out back of property, test down spout, that is emptying into soil pipe, to cold water spigot get 120v with all breakers off.
Service is 100a cable, sleeved in non-grounded emt, 100-a cable is twisted and smashed, in a lb, going into the house.
Most house's on the block are brick, stucco, with a 2nd floor bay, that is AL siding, siding is in contact with the stucco wire and stucco, all windows and barge boards are capped in AL.
Conclusion: Service cable is in contact with stucco wire, traveling to siding? Going to replace service cable on 2nd day.
Facts: 2nd day
First thing,test down spout, no voltage.
Neighbor next door asks to check a breaker that has tripped, reset breaker.
Back to next door, disconnect one leg at taps,get 120v, disconnect other leg, still get 120v, disconnect neutral and no-hub fittings catch fire, re-connect neutral.
Fire dept. and PECO on there way!
Peco tests neutrals in both houses, everything is fine.
What could it be?
