Blackburn HLC3974AP9-2 – Frequently Asked Questions
1) What conductor sizes does the Blackburn HLC3974AP9-2 hot line clamp take on the main and the tap?
The HLC3974AP9-2 handles a main run of 400 kcmil down to #6 and a tap range of 4/0 stranded down to #6 solid. If your tap is smaller than #6 or your main is above 400 kcmil, this is the wrong clamp.
2) What voltage can a Blackburn HLC3974 hot line clamp be used on?
It carries a 35 kV rating, which covers typical 15 kV, 25 kV and 35 kV class distribution work. Do not take it above 35 kV.
3) Can I use the HLC3974AP9-2 on copper conductors, or aluminum only?
The body is aluminum with a tin-plated finish. Tin plating over aluminum is what makes a connector suitable for both aluminum and copper conductors, so the clamp is not limited to aluminum runs.
4) Is a hot line clamp the right part for bonding a ground rod?
No. The HLC3974 is an electrical tap clamp for making a live line connection on overhead distribution, installed with a hot stick. For bonding a conductor to a ground rod or water pipe you want a direct-burial rated ground rod clamp or pipe clamp instead.
5) What does the protected thread feature on this Blackburn hot line clamp actually do?
It is a hot-line clamp with a protected thread design, meaning the threaded stem is shielded from weather and debris so the clamp still turns freely when a crew comes back to it later. That matters on taps left energized on a pole for years.
6) Is the Blackburn HLC3974AP9-2 sold individually or in a box?
Sold each, so order one per tap point. Count your taps rather than assuming a carton quantity.
7) Where is the Blackburn HLC3974AP9-2 made?
Country of origin is India. Useful if your utility or agency spec carries a domestic-sourcing requirement on line hardware.
