What causes an electrical tingling when turning on the water faucet? :roll: Bill Wright, Jr.
It?s usually
fault current from a shorting electrical item common to your water system that is not correctly bonded but sometimes it?s stray current
Notice Mike Holt?s comments in ?Stray Voltage in North Carolina Part 2 of 3? in M.D.?s #5 post above, This article notes two reasons voltage/current appears on water pipes:
"fault current" and
"neutral current or as some call it "stray current."
Bonding [EGC] only exists to carry fault current to source to overload the breaker (instantaneously open the breaker clearing the circuit) in the event of a short [ground fault]. This is why bonding is so important, verify all your EGC?s are in place.
Stray current will appear on conductive items because of the neutral current is in parallel to earth by grounding the neutral at the service disconnect and at the utility transformer, so earth will have different levels of neutral current at different times.
One way to test is put your voltage tester on the items that you feel the shock then turn off & on one circuit at a time until it clears, if it never clears turn your main off and if it still does not clear you have stray voltage [neutral/stray current] ahead of your service disconnect. You should contact your utility service company to investigate their side if you have stray voltage.
