One hole vs two hole compression lug application

[ARCTICSKI]

Members of mike holt's forum:


As an electrical inspector, where would you mandate the use of double hole compression lugs, other than when the mating surface is built to accomodate a 2 hole, lug mounting? Give specifics, please

thanks, dave

For code compliance .... never unless the manufacturer specifically states two hole compression lug.

I'll second that reply.

specifications call for 2-hole long barrel double indent...sometimes modified for wire bending space as these will not always fit with the allowable bendng reqruiements of the cable and equipment space avaliable..

Its never up to the electrical inspector to mandate anything.

Its his job to verify compliance with the applicable requirements, not make up stuff on his own.

I don't get the poll options.

Do you want me to email you a 2-hole hy-press connector or bring it to you in person?

If that's the case I need enough to terminate both ends of a 3000 Amp service. 12-500 MCM conductors per phase. The bolts too, if you can.

What the heck, bring it here. You can catch a movie while you're here.

The two hole lugs or NEMA lugs, work much better than the one hole for larger wire sizes, say > 1, as the lugs don't twist when tightned. Burndy makes a stacking adapter for conductors in parallel.

Tom, an open-end wrench or pair of channel pliers on the lug will help there.
