Electrical shock question
Scenario:
Have an inground pool. Have a well with a submersible pump. Both are wired to two 20amp breakers so that they can be turned off close to the pool - underground wiring. All was fine until ~ 1 month ago. Now, when the circuit for the well pump is turn ON, and you take a dip in the pool, you will get a electrical tingling sensation. Turn the breaker OFF and there is no charge. Could there be a break in the insulation of the underground romex between the pump and the breaker which caused the entire ground to "charge" and therefore "charge" the pool water? It's OK as long as the breaker is tuned off - but to me, it looks like I will be digging an 18" trnech the 20 feet or so to the well with a new line. |

Probably need to do redo both motors correctly. GFCI breakers are required by the electrical code in certain conditions. Who ever wired your pool or the well pump in romex certainly did you a lot of favors during installation. |

The new breakers are actually GFCI - the romex to the pool is a new run as is the power from the house panel. The line to the well pump probably shoudl have been replaced when we did the pool - hindsight. The previous homeowners was an idiot - they put the pool in and ran the power to the pump 1/2 inch undergraound along a sidewalk and patched it into teh 20 amp service breaker for the downstairs heatpump - just plugged it in. I had the whole thing re-routed (I don't mess with electricity) and done properly. Just missed replacing the run out to the well pump. |

The new breakers are actually GFCI When you turn the GFCI breaker off you don't feel the tingle? Then it cannot be leaking current to ground, or the GFCI would trip. (You do test your GFCIs don't you...) Even before you said that I questioned your story. Lets say there is a nick in the insulation. Why would current flow through the ground, through the pool, through you, and then back into the ground; when simply going to ground (avoiding the pool and you) is so much more direct? "Charging the entire ground" would trip the breaker, even if the GFCI was defective. I don't know what your problem is (and you should have called an electrician long ago!) but it is not a nick in the well pump circuit, unless that wire goes through the pool. |

I don't top post - see either inline or at bottom. Scenario: Have an inground pool. Have a well with a submersible pump. Both are wired to two 20amp breakers so that they can be turned off close to the pool - underground wiring. All was fine until ~ 1 month ago. Now, when the circuit for the well pump is turn ON, and you take a dip in the pool, you will get a electrical tingling sensation. Turn the breaker OFF and there is no charge. Could there be a break in the insulation of the underground romex between the pump and the breaker which caused the entire ground to "charge" and therefore "charge" the pool water? It's OK as long as the breaker is tuned off - but to me, it looks like I will be digging an 18" trnech the 20 feet or so to the well with a new line. I would not nessarily blame the wiring itself. The pump itself could be shorted. Please post what the resolution was... -- Tekkie |

it would take a massive ground fault to electrify the whole pool. A
large groumnd fault should trip a GFI. Something is strange. But if you feel a shock int he water, it is VERY DANGEROUS. Get someoine who knows what they are doing to look at it. Mark |

Get someoine who knows what they are doing to look at it. Mark is it really all that dangerous? A little tingling never killed nobody. Plus you are surrounded by water which the electricity will happily pass through just as fast as your body. of course if you happen to swin up to and touch the source of the leak, then you will have a problem. I'm actually having a hard time thinking of a scenario that would significantly energize the pool without triping the GFCI or the breaker. I suppose we should ask if the pool is actually grounded? -- Respectfully, CL Gilbert "Verily, verily, I say unto you, He that entereth not by the door() into the sheepfold{}, but climbeth up some other *way, the same is a thief and a robber."

Well, I guess we would never find out if they guy that got killed felt just "a litle tingling" or not, cuz he's dead. I'm actually having a hard time thinking of a scenario that would significantly energize the pool without triping the GFCI or the breaker. Here's an easy one; supply line. He said that both GFCI breakers were near the pool. If the previous owner is as stupid as it seems, the incoming line that supplies power to the two breakers is probably not GFCI at the main panel. A nick in this line would energize the pool if it were close enough, or if the soil types were such that the path through ground water or pipes to the pool then to ground was best. -Kevin |

Don't discount anything. First,.... GFI breaker or outlets should NEVER be used with motors. (well pumps and swimming pool filters both use them) They don't work well. The starting currents in motors can fry the electronics in a GFI And a GFI should NEVER be used to fix a "no ground" problem. And NO gfi is foolproof, they can go bad, and often do and the test button won't always show a problem I've seen the same idiots who fixed fuses that kept blowing by shoving pennies in. Move into breakers and fill the handles with crazy glue to keep them from tripping. Make sure all the motors & pump bodies are properly grounded. swap breakers with known good units. And don't forget to check any "pool lights" as well And don't swim in the pool if it tingles, or at least leave a note for your next of kin to let us know what the final outcome was. AMUN |
