CPT or GPT? (Automotive / trailier etc. general purpose wire, aka "primary wire")

 

I believe CPT stands for compact. Stranding type.

 

Me too ...

 

Err…..

Could find more on CPT cable strippers than CPT wire or cable itself

I can't post a pic for some reason, the buttons are grayed out.

 

sometimes i have to click it a few times

Did you buy those off eBay or something? Maybe you aren't the first person to ask, and they spell out COM on the newer IKL-47 crimp splices

 

I have to buy these on eBay, they are not typically used by our POCO therefore our suppliers can’t really get them for a decent price. They are not in Graybar’s inventory

 

The IKL splices are larger internal diameter than the same size standard aluminum compression splice. They are larger to accommodate the larger diameter of acsr. With the internal diameter being larger, it generally takes a smaller size smaller compression sleeve to take a compact stranded wire. So you'll find them marked for example 250 CPT 4/0str 4/0 acsr.

 

Im kind of assuming we can use our MD6 tool to crimp these. I think the 250 die, placed in the rear jaw works on this size. It, of course is too big for the popper tool

 

W-K840 or W-249 is the correct die. A 4/0 AL die would likely work too.

 

Your sheer bolts won’t work on these ?? They work on 4160

 

The shearbolts are massive and start with 4/0. I could just use a 2/0 barrel or butt splice and use heat shrink but, the conductors are for a fire pump. I didn't just want to use polaris taps on this cable.

 

This fire pump controller is fed line and load with 3/0 Aluminum. We couldn't get the 2 hour rated cable in Aluminum or in 3/0 copper, we used 2/0 copper in place of the 3/0 Aluminum
