Crimping 300 al

[liquidtite]

When buying crimps do they make specific crimps for the specific brand of crimper ?
went to start to crimp with a burndy hydrolic and the size dyes did not match up to the size of the crimp?

also I noticed that a 250 kcmil,al, single hole crimp fit on a 300 kcmil al conductor is this normal.

It was my first time crimping with lugs I've only done barrel splices .

thanks for your time

It's been a while, but last I saw is was color coded for each tool to use for each crimp.

I'm sure you can find some charts and graphs via your favorite search engine.

Was the 300 a compact strand conductor?

Yes I looked at the 300 a conductor today and it says compact on it .
I noticed that the strands on the wire are square .

whats the purpose of compact wire ?

...whats the purpose of compact wire ?

Its smaller diameter often permits you to use aluminum conductors in place of copper conductors without increasing the conduit size.

You definitely need the right crimper with aluminum lugs. Using anything else just wrecks the crimp.

EDIT: Just found this video, I didn't realize this cordless Burndy was the proper crimper for aluminum. We actually own this style crimper, but up till this point I've only used it for those heavy copper c-taps. I'll have to give it a shot next time I need to crimp some aluminum!

Several of our customers specify that we only use the crimper that is approved for that lug or c-tap. Be it Burndy, Panduit T&B, etc, etc, etc
