Wire connections

[madferraristi]

When connecting, say, a #12 STRANDED wire to a duplex outlet that has screw terminals only, I was taught, years ago to strip the wire about 11/16" and then cut an additional 3/16 of insulation and push it to the end of the wire.

Then when the wire is wrapped around the screw and it is tightened, the wire can not spread out and stays under the screw.

I was told recently that this is not acceptable and a crimp-on terminal MUST be used for stranded wire under a screw head.

TRUE OR FALSE???

A second FALSE here. Ask where the back up is.

IMO, you had a good teacher.

Charlie,

What do you mean by your comment?

Is this method acceptable (perhaps not ideal) but was the guy wrong when he said it was illegal?

Re: Wire connections

Even though I answered false, I agree this is less than desirable and "crimp on" connections are a prefered installation. This is not meant as an answer for Charlie.

My answer of False is based on UL standards (RTRT)

Re: Wire connections

Crimp is not required by code, but IMO it is a better method if using the proper terminal and tool listed as a unit.

Where I work we specify stranded wire and specific terminals and tools..
