kylenotkurt Posted April 26, 2021 Report Share Posted April 26, 2021 So I bought a brand new MasterSpas Twilight 7.4 about two months ago. It’s been working great- until two weeks ago I started feeling a small current of electricity coming off of the water. Thur multimeter reads the voltage at about .4V in the water and I can also pick up 1.0V on the waterfall metal coping. The electrician that installed the tub has been out here for about 8 hours total checking everything. Unhooking and changing out grounds, checking the breaker, checking the utility poles at the road, nothing seems to make this go away. We even disconnected everything from the hot tub. And I mean everything. The grounds and all of the electrical. Still getting voltage from the water and actually too picking up 0.4V from the terminals where we disconnected the wires. what is going on here?? The tub is on a concrete slab, recently poured 4 months ago. Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted April 26, 2021 Report Share Posted April 26, 2021 Had a job up on a lake in northern Ontario. Same situation... disconnected the spa completely from the electrical and was still getting a mild tingle shock. Called local Hydro and it turns out they had a bad transformer on the other side of the lake and it was sending current through the Canadian Shield granite rock formation. Had to be over a mile away. Not sure what the fish were thinking...lol. Let us know when you find out what the cause is/was. Call your local hydro 1 Quote Link to comment Share on other sites More sharing options...
ciderjack Posted April 28, 2021 Report Share Posted April 28, 2021 When the electrician puts his meter on the incoming power at the tub, is he getting 120v on each leg? Quote Link to comment Share on other sites More sharing options...

There is power leaking to the ground somewhere in his neighborhood. Hope @kylenotkurt reports back Quote Link to comment Share on other sites More sharing options...
