tingle shock

[enireh]

we have a slight tingly shock in the dryer and washer when running. I opened the outlets feeding both and everything checks. the washer outlet has a secure hot neutral and ground and the dryer outlet has two hots and a ground all checking out. outside at the ac/heat unit this past Sunday we heard a yelp and the neighbors dog was laying there dead. I ran a rebar rod in the ground about 18" and checked it with the tester to the casing on the unit and got nothing. the unit has two hots and a ground running to the disconnect and then to the unit and it checks out ok. I found that the sub panel has three wires servicing it. there is a ground wire going down and under the house to a smaller size ground rod like for an electric fence. I installed a 5/8" x 8' ground rod and ran a #6 wire to the ground bar in sub panel. The main panel is 150' feet away and if I need I can try getting a ground wire out to it from sub panel.
what do you think? did I overlook something? the neutral bar at main panel is bonded to the enclosure

thank you

Sounds like a main bonding jumper missing in one of the panels.

Does the sub-panel have the neutral and grounds tied together?

I’m betting an open service neutral, current is returning on the bonded water line via the neighbors service. High return resistance.

Have you verified that the equipment grounding conductor between the main panel and sub-panel is good?

He's saying there isn't one.

He's saying there isn't one.

And if there isn't one, and there is a neutral problem, the impedance of the earth electrode path is not going to do much good at all for safety.

The dead dog might be an indication.

What is a "slight tingly shock" to dry skin can be a lot worse to a wet tongue.

That's what it sounded like to me too. But I was giving him the benefit of the doubt, since if it didn't exist it certainly wouldn't be "good".

no

no

no

There's the problem. If your feeder is only 3-wire, the neutral-ground bond must be made.

Male dog?
kinda off topic but wondering if dog was taking a whiz on the AC to get up to fatal current?

Not OT. Exactly what I pictured. GD was being polite.

could possibly be a gf in the AC unit.
