Default Bending big wire

Do you folks have any favourite methods for getting big wire to sit properly in the lugs? Even the 14" Klein cable benders only have a capacity of 500 mcm, and I've got 600 and 750 to deal with. I'm just curious what the favoured methods are. I'm not worried about little stuff like #2, just the big stuff.

Drill a hole in a a few 2x4s at different angles or make up a piece or unistrut with some 3/4" bolts spaced a couple of inches apart.
Or
stick the wire in the end of a piece of unistrut.

I take a piece of 2" EMT and file it real good, then I wrap the end of it with black tape. I make it thick and I go over the edge so that I can fold it back in.

This works better than anything else I'd tried.

When I was a kid, I used to just bend it and then tighten it up with the long part against my solar-plexus and just pull in with both hands.


I don't know if I could do that again. Most guys used a bender if there was room. if there wasn't, they would use either the pipe or drilled 2x4 method

If I'm using lugs, I usually bend the wire to fit, and take the lug off. Install the wire into the lug, then screw the lug back in place and tighten.
Then fully tighten the lug screw, with the wire already in it.

FWIW, That size wire, I would use crimps instead of lugs.

Could you define "ignorant"? If so, you'd know that you used it wrong.

I don't know if this would be kosher on construction, or not, but when we have large conductors and the lugs in the panel are kind of close to the top we install an entry box right above the lugs on the top of the panel. You still have to form the wire but it gives you a lot more length of wire to deal with, and then insert into the lugs.

I've done the same thing. I had one a few months ago with a 1200A breaker and the lugs were about 4 inches from the top of the cabinet.

A lot of these machinery manufacturers could care less about the installers.

I like to use the end of a bender handle to bend wire. It's long enough that you can get good leverage and the end is rounded so it wont hurt the insulation.

You can't use him because rat guys can't afford union helpers.
