I bet is ground. Buy green elektical tape and you are done and even fine with the code.(in CA). Cheap and fast. If not, you should rewire the complete outlet. But I almost would bet it is ground.

My guess is this is a retrofit ground wire, added to upgrade a two-prong receptacle to a three-prong. If this is the case, the wire would go from the ground terminal on that receptacle to another ground - the code allows several things for the other ground. It should not be orange, instead green or bare, and it should be installed in a more "neat and ...

The danger of connecting the green wire to a ground that doesn't go all the way back to the panel is that if the fan has a ground fault, the ground wire will not carry the fault back to the safety of the panel, and instead will distribute the ground fault to everywhere on that island of grounds. So all the grounds will suddenly become hot. I would leave ...

Insert a screwdriver in the small rectangular opening in the back of the switch, just below the wire, and push / twist until the old black plastic switch breaks into pieces. Eventually the wire will come out. I despise these back stab switches and outlets, which the builder of this 1989 home I purchased in 2012 used exclusively.

With a 3 wire system the only way I would know to find the problem would to add an impeadance (resistor) in each apartments ground and measure the voltage. The only way to prevent the problem is to ass a rcd to each apartments supply and when the current on their ground raises to 50 ma it will trip the offending apartments breaker (I believe RCD breakers are ...

Sounds like an unsafe situation. To find the offending circuit, monitor the ground while opening/closing each breaker.

There should be another breaker upstream of the broken breaker.

That socket is wrong, and was wrong at the time of installation. The person probably had a leftover socket lying around and went "whatever". I myself had a NEMA 10-50 in my stocks; I threw it in the trash rather than risk someone installing it. You cannot ever use NEMA 10 except to repair a broken outlet in dryer or range circuits which predate 1989. ...

Hot and neutral wires are working wires. Ground wire is a security/reference wire. Any connection may loosen over time. When hot wire gets loose, you'll notice it immediately - the devices behind the failure stop working properly. Same apply for the neutral wires. On the other hand when the ground wire gets loose you want to have as few devices affected as ...

In addition to what @ThreePhaseEel said, the purpose of having two screws on each side is not so that receptacles can be wired in series. While that is allowed, the purpose is for "split receptacle" setups, where only one outlet is controlled by a switch (or each is controlled by a separate switch). This is done by breaking the metal tab that joins the two ...

I am glad you are finding it convenient that some devices allow themselves to also be used as splice blocks. However, that is prohibited for certain types of wires: Any and all ground wires Neutral wires on multi-wire branch circuits That is because it will cause serious problems for other (e.g. downline) loads if those connections are severed due to ...

This is because removing a device isn't allowed to interrupt grounding connections Removing a wiring device from the circuit cannot break grounding connections, or else you are violating NEC 250.148(B): (B) Grounding Continuity. The arrangement of grounding connections shall be such that the disconnection or the removal of a receptacle, luminaire, or ...

I contacted the company. The long side goes inside the box.
