Feel Electricity running through air duct??

PICOGRAV · Oct 1, 2013

The copper pipe would be best, scratch off the coating if there is one and screw it on tight with a nut and bolt so you know it wont come off, the end on the duct should be one end of a copper wire with a fitting with a hole that will go around the bolt like a washer and the other end of the wire should be connected to the pipe, same deal, rough it up and I would solder this end on if you can if not, nuts and bolts or a clamp, I would do two ground wires to be safe shit.

I would ground the main ducts part with the fans in them.

I found the problem!!!! I started testing one set at a time. connecting the fan then the ballast/light...i did the first set had no problem/current in duct so shut it off, did the 2nd set and it was all clear, did the 3rd set and felt the current in duct. The only difference in how i connected the fan to the first two lights was that the other two lights had the 6" T at the end of the fan to connect the air ducts to the next light. This being the last light i connected the air duct directly onto the fan using a 6" metal clamp...i guess the metal clamp can not be so close to the fan because it will carry the current into the air duct. I removed the clamp and air duct turned on the ballast and fan and the shock was gone.

Just wanted to pass on this information in case anyone ever has a similar issue. I do have clamps where the air ducts connect to both sides of the T but not on the part that connects to the fan. i just used the tape there, and these two lights are the ones not having any issues.
Thanks for all the input everyone.

There are copper pipes near my room so I will try to ground there.

i dont know if anyone caught this i havent finished reading all of it
Dont ground to water pipes
the last place you want to be is in the shower with a stray current

tekdc911 · Oct 2, 2013

and if its coming from that fan i would check the wiring internally on it
i cant see it being a clamp doing it
if its not getting a connection without the clamp the fan is probably still hot if you grab it
if you found the fan with the problem
either troubleshoot the fan and remedy or replace it

That is not possibility, the copper pipes should always be apart of the ground system, for safety, if they where installed correctly they will already be grounded, so if he cant get to the main ground, at least this willmake it safe in the mean time.

Explain how you would get a current through the shower if this was the case? I would like to see you back up your clams...

You need to read the hole thread, if you don't understand whats was happening with the stray currents just ask...

I removed the clamp and touched the fan while it was running and the stray current was gone..I just connected the air duct with tape since I don't have room for an elbow...turned on all the lights one at a time and there is no shock anywhere like it should be.

Copper pipes should be safe since whoever owned house before me used a copper pipe to ground the water softener system..
Thanks again

here let me google it for you
since you're so apt to puff your chest up and be a smart ass

you can be a troll i could give a shit less but dont do it when safety is involved

https://www.google.com/search?q=stray+current+in+the+shower+&oq=stray+current+in+the+shower+&aqs=chrome..69i57j69i60l4j69i59.7111j0j7&sourceid=chrome&espvd=210&es_sm=93&ie=UTF-8

if you dont know what you talking about then please refrain from speaking
if the tub is a shorter run than to the ground on the pipe or the ground cable then you could very easily BE the ground

you are correct the pipes should be grounded
but how do you know they are and its not a 100' run and your 25' from the source and grounded out on the tub

So you are saying the electricity would rather run through a person (1,000 ohms to 100,000 ohms) then a copper pipe (about 0.723 ohms per 2000ft at 1.5 inch diameter)?

Your stupidity gets me all laughing and shit.

>.< but there is record of it happening
it can happen
pipes are grounded for safety

not for working loads if he has a stray current then something is BAD and needs to be repaired or replaced
my fan the same fan doesnt have a ground at all and it doesnt shock me when i grab grounded objects
my "stupidity" is common sense

have you ever welded on large scale ive had grounded metal frame buildings shock me leaning against it with soggy ass boots with welders up in the purlins

even if the resistance of a human is more than the resistance of copper the electricity doesnt go ohh snap! i cant go there the resistance is too high
it just goes , but less of it, since the "resistance" is higher as you pointed out
