how to know if unknown wire is "neutral or ground"?
I'm trying to add an outlet from 2 wires that are just hanging out of the wall. I followed the wires to the attic and only one wire goes to the attic. The other wire went somewhere else.
I tested the one of the wires and found out that it's either a ground or a neutral. How do I find out for sure if this is a "ground" or "neutral". If it's a neutral, then this outlet I'm trying to add is almost complete. I will just need to run a hot wire to the wire in the attic. However, If it's a ground then I will need to run a new romex.
(PS. I posted the same question on DIY and the administrator there closed my thread and instructed me to go to this website.)

It's not my place. However, the owner is paying me to do this. I'm asking for help to make sure I'm doing it correctly.
So how do I know if it's a neutral or ground wire?

You will be responsible for any problems and could face legal retribution.

Your trade is "Plumber". I would suggest hiring an electrician. Two wires coming from different areas would be a serious bell-ringer for me.

You do know that electricity is a dangerous thing. Right? You should probably tell your landlord to hire a professional.

A professional will not do this job. That's the reason I got hired. The electrical in this house is not Code Compliant. A electrician will only rewire the whole house at some $5,000.
Can you please help me and let me know how to know if it's a neutral or ground?

If you don't know how to figure this out you should not go near electrical work..This is pretty basic stuff and the fact you don't have a clue should be a wake up call.

I replaced a whole circuit breaker. I've worked on electrical for some 20 years. So I have some knowledge.
A professional will not take this job. The wiring in this house is not code complaint. Please help.
How do I know if the wire is neutral or ground?

I'm sure it's not the doorbell wire. The doorbell works fine. Also, the door bell is usually thinner wires. These two wires are electrical for sure.

I am so glad I was not drinking anything when I read that because it would have most definitely shot out my nose!
