I have found 6 receptacles on the same circuit, all of them open ground. I have rechecked the grounds and commons in the main panel, and actually tightened all of them again. Didn't find anything amis at the main box. Two of the recep boxes did not have grounds, so I fixed them, and actually replaced all 6 receptacles. Still have the issue. I checked every switch that we have and nothing appears to be on that circuit. It is all receptacles so far. Is that normal? I even checked all of the motion sensor lights , and nothing included in my circuit.


Any ideas out there? Even though the breaker has not tripped - could it have gone bad?

Could any other circuit be involved?

What precisilly is your problem ?
Is it just no ground ?
If it is, then the breaker would have no effect,
on an open ground situation !
Do you have hot and neutral at the recepticals ?
Are all these recepticals on one power circuit ?
And do you have earth continuity thru all these outlets ?
Do you know which is first in the power chain ?

What do you mean by "two did not have grounds" and how did you "fix" them.
How old is this house.
Got a picture of one of the outlet boxes opened up?

There were no ground wires on the ground screws of the receptacles. I used the wires inside the box to go to the screws and also ran a ground wire to the metal boxes they are in. I basically copied one of my good outlets. No pics.

So then there are ground wires in the boxs ?
And the boxs are also connecttted to the wires ?
Next step would be to find which is first in chain,
And find where the earth wire goes to or comes from !
Maybe goes no where !
In which case you should run an earth line
from your panel earth to the first in chain.
And also check for correct earth at panel !

I checked the earth ground, found it loose - thought we had it. But no change. If it was a loose earth ground wouldn't it effect all of my circuits and not just one? Also should I scrape the wire up and down on the rod to make sure it has a good connection? There is also another empty and loose bracket that is attached to the rod below the one I tightened. It has no wire in it. Do you think someone just upgraded to the one I tightened, or am I missng ssomething?

Dude, this has nothing to do with the little hole on a receptacle, best bet is to call someone with a little bit more electrical knowledge...

stickboy1375 I wired an entire 1400 sq" addition to my house, in Mullica Hill, NJ a few years ago, which included upgradeing my main to 200 anp, adding a subpanel at my pool 75" away to allow for more expasion. All kinds of 2 way , 3 way switches, outlets, and am not or do I ever claim to be an election. I did that entire 2 story addition, to code, with no electrical errors or problems. Electrical work is not rocket science - however I am getting whooped by this open ground, and appreciate any help. I actually though he was asking me to check the earth ground. I got carried away when I saw something loose!

and just because it works, doesnt mean its right... or you understand what you're doing.. but if you are checking a ground rod for an open ground on a receptacle, then you definitely, don't know what you are doing.

You need to start at the first outlet in the chain,
Follow the cable back to the main panel,
Check all joints in this line.
if there is a valid earth in the panel
and no valid earth at the first recepticule !
then its obvious, its a faulty cable
or an faulty unknown joint,
there could be a box/joint buried in a wall
somewhere that you dont know about.

Do you have any valid earths in the house at all ?

The breaker has nothing to do with an open ground other than it won't trip on a ground fault if one occurs at one of those receptacles.

It wouldn't effect any of them ...the earth ground has nothing to do with your problem of an open ground on one of your branch circuits.

Why do you think it would?

The simple matter is your equipment grounding wire is open somewhere, my guess is you are missing something that is on the circuit or a junction box.
