I was getting ready to run an outlet off this existing outlet. First tree ground wasn't connected and three was a jumper you can see in the pic. It's this normal practice. I've never seen it before.

It looks like the wiring was a two wire system. For a while they decided that grounds were necessary and did not pull a ground conductor. The neutral wire which is the white wire is at Ground potential in the panel so basically it is grounded just like a ground wire would be so they are putting a jumper between the neutral screw and the ground screw so as to ground the outlet. This is not cold legal. The proper fix would be to go buy a two wire Outlet which is an outlet that has the two vertical slots but no round ground hole and put that back in. People change and put 3 wire outlets on so they can plug things like plug strips and other devices with ground prongs but it is neither safe nor legal. If there is a green or bare ground conductor in the box then you can use that to bond to the green screw and use a 3 prong outlet otherwise it should go back to the old to wire original scenario

* unnecessary

I see this all the time and it is a scenario that will work and provide both a neutral and a ground but like I said as per your electrical code there should be a wire for the hot a wire for the neutral and a wire for the ground.

@Placidseven - MO ^^

Agreed

The jumping of neutral to ground is to trick an inspectors plug tester. This is a hack job "electricians" work

The ground isnt even wrapped the right direction

It's weird because there were 2 ground wires in the box they just weren't connected. Which makes me worry there is a bad ground.

I'm going to buy a cheap circuit tester and do some investigating.

Well all the grounds are good on that circuit. Unless anyone can think of something I should check, I guess I'm going to hook it back up.

Do a resistance check from neutral to ground. The grounds and neutrals typically are bonded at the panel. Sometimes you will find floating neutrals which means its isolated. However the xo bond coming from the secondary side of transformers creates ground aka your zero reference point

Yes go ahead and make it all up include your new wire that you were going to run twist all your light colors clockwise under a wired nut with the short jumper wire to your individual device and It will give you best results

Here is a splice with 3 nm cables and the jumper wires to the outlet. Twist wires clockwise as this is how the wirenuts tighten

So after testing all the outlets on that circuit ( and the rest of the house which is ok), the receptacles on that breaker all have an open ground. Looks like I get to spend some quality time in my attic tomorrow.

@Lebens I'll give this a try tomorrow too

@Placidseven - MO run a new feed

@Lebens i most likely will. I already have the dry wall cut away from running stereo wire and cat5.

@Placidseven - MO and rebuild the ckt like greg sharded a pic of

Yeah I'm using that on all my receptacles for now on. Very clean.

This method also changes the ckt to parallel. In parallel ckts the device can fail and usually will not disable the whole ckt as it will in series

Very cool

Just wanted to give a thanks to @Lebens and @Deleted User. I got my issue resolved. It was a ground that had been painted over.

Crazy stuff. Glad to help. Hope to see u in cville!

Anytime

@Lebens u going to cville

No sir. During the summer i work non stop. Feast or famon and ive got plenty of mouths to feed brother

Installing a furnace today

out with the old

in with the new

I know its not electrical but my skills are diverse..... and diversity is our strength goys

👌

Any of you guys know what this is. It was wired up to a light receptacle in my basement.

Low voltage step down transformer

@Placidseven - MO are you remodeling your home?

@RevStench more like fixing a poorly remodeled home

Oh haha Well I guess you know some things are done right now.

For the doorbell @Placidseven - MO
