Is there a good way that you know of to properly terminate a conductor in a case like this??
This #6 is too big for the terminal.

Hey, ALL the conductor is under the terminal at least it was not wrung off (something I've never done ) .

It appears as the type of terminal that will take a conductor on either side, or both as in the case of Square D.

That said, you can splice if there's room, or buy a mac adaptor that reduces the size of the conductor entering the terminal, I think these are made by both Burndy and Ilsco. We used to use 'em for circuits like parking lot lights where you'd have 1/0 for a 20 amp circuit.

Either way, the picture you show doesn't make me 'pucker' it looks like a pretty good installation.

Let the flames begin

Different possobilities

-Cable lug, open at the front (fork style)
-using a proper diameter
-Installing Termination block, too big cables in at the one side, and wires suitable for the contactor out on the other side.

BTW, were these Wires Stripped with a side cutter?

It looks like all the strands are damaged at the end of the insulation, because somebody used a side cutter...

The marks on the copper strands are typical of what you get when the hole in the stripper is a little small- say, using a "solid" on stranded, ot a #10 on #8. Since even the right stripper often leaves similar marks, and the strands are not particularily weak at the mark, I tend to consider the marks more cosmetic, rather than scored. (At least at 60 hertz).
Yes, the wire is larger than the terminals can comfortably handle. I consider this a borderline installation method. I fault the component manufacturers, as this situation comes up all too often; enginers sometimes use too sharp a pencil.

I agree, I have seen it plenty of times and it works fine.

I will not do this as it is wrong, the terminal has a size rating and I will not exceed it.

I have had good luck putting small 'foot lugs' on these 30 amp contactors.

Still a possible UL issue but I doubt the terminal is actually 'rated' for a mac adapter either.

I'm guessing an 8-32 teeter washer terminating 8AWG? Oy.

Thanks for the suggestions!
I don't get in any uproar about this really, I just wondered if anybody knew of a neater way.
The "pin connectors" are a good deal, I didn't realize they were made in that small a size (is that the same as a "mac adapter"?).
