Blackburn CTL500L-58 – Frequently Asked Questions
1) What wire size does the Blackburn CTL500L-58 compression lug take?
The CTL500L-58 is sized for 500 kcmil copper conductor. It is a copper compression lug, so it goes on copper cable only, not aluminum. One conductor per lug.
2) Can I use this copper lug on aluminum 500 kcmil feeder?
No. The CTL500L-58 barrel is copper and is rated for copper conductor. Aluminum cable needs an aluminum-bodied or dual-rated AL9CU compression lug with the correct oxide-inhibiting compound, not this one.
3) What does the brown color band on this Blackburn lug mean?
Brown is the die color code for this lug. The barrel is marked brown so the crimper knows which die set to use, and an inspector can confirm from the finished crimp that the correct die was applied.
4) Why choose a long barrel lug instead of a standard barrel for 500 kcmil?
A long barrel takes two crimps instead of one, which spreads the pullout load over more of the conductor. On heavy feeder sizes like 500 kcmil, and on terminations that see vibration or high fault current, that extra crimp is why specs call for long barrel. If the spec sheet just says compression lug and space in the gutter is tight, a standard barrel lug is the shorter option.
5) Do these Blackburn lugs come in bags or are they sold individually?
They are sold each, so you order the exact count you need. Terminating both ends of a three-phase 500 kcmil feeder with neutral, for example, is eight pieces.
6) What is the exact part number and where is this lug made?
Blackburn CTL500L-58 is the manufacturer part number, a one-hole long barrel copper compression lug for 500 kcmil with a 5/8 inch bolt hole. Country of origin is Mexico.
