Blackburn CTL750-58 – Frequently Asked Questions
1) What conductor size does the Blackburn CTL750-58 compression lug take?
The CTL750-58 is sized for 750 kcmil copper conductor, which is what the 750 in the part number designates. It is a copper compression lug, so it goes on copper cable only, not aluminum.
2) What voltage is the Blackburn CTL750-58 rated for?
Rated 35 kV, so it is suitable for medium voltage terminations as well as ordinary 600 V service work. That rating is what lets it be used inside 15 kV and 25 kV class switchgear and pad-mount terminations where a 600 V lug would not be acceptable.
3) Can I use this copper lug on aluminum 750 kcmil cable?
No. The CTL750-58 is a copper-bodied compression lug intended for copper conductor. Aluminum cable needs an aluminum or dual-rated AL9CU connector with the appropriate inhibitor compound; putting aluminum into a copper-only barrel creates a dissimilar metal connection that will not hold up.
4) Is this a one-hole or two-hole lug, and does that matter for NEMA pad spacing?
It is a one-hole lug (1HL in the part description), so there is no center-to-center pad spacing to match. That makes it straightforward on a single stud or a drilled bus, but if your gear is prepped as a two-hole NEMA pad you need a two-hole tongue to get both bolts engaged.
5) What is a short barrel lug and when should I use one instead of a long barrel?
Short barrel means a single crimp length rather than the extended barrel that takes multiple crimps. It is the choice when space in the cabinet or termination compartment is tight and you cannot get a full long barrel plus tooling into the bend. Long barrel versions are used where a longer pull-out length is specified or where the barrel doubles as extra conductor support.
6) Why is this lug black instead of bare copper, and does the coating affect the crimp?
The CTL750-58 ships with a black finish over the copper barrel and tongue. The plating is a surface treatment only; the body is copper and it is crimped with the normal die for a 750 kcmil copper compression lug. Clean the tongue face at the bolted connection as you would with any plated lug.
7) Is the CTL750-58 sold individually or in a bag of multiples?
Sold each, so you order the exact count you need per termination rather than a fixed pack. Terminating a three phase plus neutral 750 kcmil feeder means four of them, one per conductor.
8) Where is the Blackburn CTL750-58 made?
Country of origin is Mexico. That matters if you are supplying a job with domestic-sourcing language in the contract, since this one will not satisfy a Buy America requirement.
