Blackburn HLC3974-2 – Frequently Asked Questions
1) What conductor sizes does the Blackburn HLC3974-2 hot line clamp accept?
The HLC3974-2 takes a main run up to 4/0 stranded and a tap down to #6 solid AWG. That range covers most utility and distribution taps, so if your tap conductor is smaller than #6 solid or your run is larger than 4/0, this is not the clamp for that connection.
2) What voltage is the Blackburn HLC3974-2 hot line clamp rated for?
Rated to 35 kV, so it is suited to medium-voltage distribution work rather than secondary or service-entrance connections. If your circuit runs above 35 kV, specify a different clamp.
3) What does the protected thread on the HLC3974-2 hot line clamp do for me?
It is built as a protected-thread hot line clamp, meaning the eye screw threads are shielded so they stay clean and turnable after exposure on the line. That matters on a clamp meant to be installed and removed with a hot stick, where a seized thread means the whole clamp gets cut off instead of reused.
4) Does the HLC3974-2 come with the 3/4 nut, or is that ordered separately?
The 3/4 nut is part of the clamp as supplied. It ships as a single complete clamp, sold each, not in a bagged multi-pack, so order one per tap connection you are making.
5) Is the Blackburn HLC3974-2 a grounding clamp or a live tap connector?
It functions as an electrical tap connector for hot line work, used to land a tap conductor onto an energized run. It is not a pipe or rod ground clamp, so do not substitute it for a grounding electrode connection.
6) What part number should a distributor order for the Blackburn bronze hot line clamp with the 3/4 nut?
Blackburn HLC3974-2 is the manufacturer part number, and it is the only configuration offered under that designation. Country of origin is India.
