I am working with an electrical socket and I need extra length on the ground wire. It doesn't seem unreasonable that I can attach an extra three inches to the existing one and attach it with a copper wire crimp. Does anyone see a problem with this?

I have no extra slack on the rest of the wires, so I am not able to pull it through any further.

This is the type of crimp I am talking about, but I guess it's crimp sleeve

What gauge wire? Can you clarify what you mean by "copper wire crimp"? Perhaps link to a specific product? Have you considered wire nuts and push-in wire connectors? – Jay Bazuzi Jan 21 '12 at 22:43

14-gage wire. I updated my question with a pic. I guess it's actually called a crimp sleeve. You put the ground wires through it and the crimp it with a pair of pliers. – oscilatingcretin Jan 21 '12 at 23:26
I just noticed the last sentence in your comment. I never thought of using a wire nut since I only liken those to hot/neutral wires. I suppose they would work the same for ground wires, though. I'll give it a shot in a few days. – oscilatingcretin Jan 22 '12 at 1:13
@oscilatingcretin - Jay's right, you can add a wire on a crimp and attach it to the ground on the receptacle/socket. Jay should add this as an answer and you should select it as an answer and give him an up vote also. – lqlarry Jan 22 '12 at 2:54

Technically, you should twist the extension bare ground wire to the short one and secure it with one of the copper crimps like you have pictured. A wire nut certainly would work , but it should be green. Practically speaking, either way will work and be safe, just a matter if you want to follow current NEC standards.

This is what I had done (twisting and securing with copper crimp sleeve). Thanks for the reassurance. – oscilatingcretin Jan 23 '12 at 14:20
@shirlockhomes could you point me to the article in NEC that says to use green wire nuts? I've searched and searched, and I haven't been able to find it (though they do use some odd language in parts, I could just be misreading it). Trying to learn as much as I can, so I can give better answers. – Tester101♦ Jan 23 '12 at 21:44
