Howdy guys!
Most of my machinery as decided to start shocking. Just little irritating buzzes. The Lortone cabber, Gryphon, a bench grinder and the latest the Foredom spindle. There all all different circuits.
I cleaned and reconnected the ground wires on the Lortone and Gryphon. That seemed to have stopped it. Haven't got to the Fordom yet.
This seems to be a irritating hazard of electric motors/grinders having had many motors in the past doing it.
Any thoughts ? Other solutions ?
Thanks Ed

I am beginning to have the same problem in my shed... everything goes through conduit and the metal is building a static charge to give you a nice little zap !!!... you will probably need to hookup a couple ground wires at your outlets, conduits or switch boxes & run them to the ground outside to dissipate the static charge building up.

I had a 40 lb. HP tumbler before. With the lights out in the garage you could see static sparks between the metal barrel and metal roller guide wheels. Other than that no sparks or shocks. Are you using a GFCI circuit? Also check your main panel. In AZ you don't always find a "bonded neutral" where the neutral is grounded at the main panel.

Sometimes high humidity will cause that. Although it may not be the exact cause.

Telephone problems, cable and internet problems, now electric motors shocking. Something going on in the atmosphere? I'll bet someone knows, they're just not telling us... Jean

Electricians gloves? Have your wife touch everything first? If it keeps it up you can run a wire from each thing that is shocking you to a positive (not a maybe) ground. Where the electricity comes into the house there should be a copper rod driven into the ground and a wire hooked to it. If things are super dry the rod may not be able to get the ground to the ground. If there is extra wire drive the rod down a little and pour some water around that area. If there is not a good ground out there you could be in for a much worse shock if something goes haywire. A very simple piece of the electricity but one of the most important. Jim

Thanks for all the diagnostic guys ! I'm surprised no one else as really experiences it which is good!
But being around electric motors in the sharpening biz I experienced it a lot.
Yet, this problem with the rock grinding equipment just started. An when it rains it pours ! Well bad analogy when talking electricity Ha Ha :nono:
But cleaning the ground wires and re-connecting them on the Lortone & Gryphon seems to have ended the problem Although the real test will be this weekend In the meantime-- I'm going to do the same on my Foredoom see if I can't fix that. Then I can straighten the spindle

Ed, Make sure your grounding is intact and don't become part of the circuit. These two rules will keep you on the safe side and 99.9% bite free

sometimes I have a rock in one hand on the Lortone and the other hand is groov'n on the Gryphon that's in the electric loop but my multitasking days are ending...mostly or maybe it my metal stool ? but I have that on the rubber mat I really think its faulty ground wires on the motors over time they loosen, corrode ect... so if anyone experience such a shock check that!

I have been out in the rain with power tools and a breaker always tripped before anyone got shocked. But dry air especially around a vacuum or dust collection system will cause enough spark to burn you bad. I have run small copper wires from the motor housings to building beams in woodworking shops to keep from getting hit. If you are running a heater it can dry out the air. My truck has never shocked me until we get dry cool air and I side off of the seat and go to close the door. Then SNAP!

Ed is in Phoenix. Dry air is pretty common.

I'd like to believe this was some sort of atmospheric phenomenon Because it seemed all my machinery was biting me at once
So I've checked and reconnected all the motors ground wires.
I've used the machinery for hours & hours now

I'm inclined to think that it is the ground from the main panel that is causing the problem. I think Jim is on the right track.

...Have your wife touch everything first? ... Jim ROFL!! Glad everything checked out okay and you're not getting zapped any longer, Ed.

well.. if it was the main panel wouldn't I be having problems with other devices connected to that panel? mostly

Re-grounding is always easier than getting you hair straightened ... Well, maybe not, for you and me, Ed. Kris

do a new ground field out side then ground your box

its interesting cause I'm reading lots about ground fields and rods is that like lightening rods?

Post by mohs on Oct 20, 2012 11:41:31 GMT -5
to be a little more specific Phoenix area homes and AZ in general weren't built with lightening rods and this state is a highly rated lightening striked area
as I understand the east as lightening rods attached to their houses I know this is not for general grounding of the main electrical circuit or is it?
