Blackburn HLC3974AP9-1 – Frequently Asked Questions
1) What conductor sizes does the Blackburn HLC3974AP9-1 hot-line clamp take?
The HLC3974AP9-1 hot-line clamp is rated for 3/0 through #6 ACSR and 4/0 through #6 solid AWG conductors. If your run is larger than 4/0 solid or smaller than #6, this is the wrong clamp for the tap.
2) What voltage class is this Blackburn hot-line clamp good for?
It carries a 35 kV rating, so it covers distribution work up through 35 kV classes. For anything above that class, you need a different clamp.
3) Can this clamp be used on aluminum and copper conductors?
The body is aluminum with a tin-plated finish. Tin plating over aluminum is what lets a clamp be used on either aluminum or copper conductors without setting up a galvanic couple at the contact surface.
4) What does "protected thread" mean on the Blackburn HLC3974 clamp?
The eyebolt thread is shielded so it does not pick up corrosion or debris while the clamp sits energized on the line. That matters because the clamp is installed and removed with a hot stick, and a fouled thread is the usual reason a hot-line clamp will not back off cleanly at removal.
5) Is a hot-line clamp the right choice for a permanent tap, or should I use a compression connector?
A hot-line clamp like the HLC3974AP9-1 is built for taps that get made or broken on an energized line, and for temporary or switchable connections. For a permanent tap you never intend to open, a compression tap connector gives a sealed, non-mechanical joint and is the better call. Use the hot-line clamp where the tap has to come apart again.
6) Is the HLC3974AP9-1 sold individually or in a box quantity?
It sells each, so one clamp per unit ordered. Order per tap point rather than by box.
7) What is the country of origin on the Blackburn HLC3974AP9-1 for a utility submittal?
Manufactured in India. Utilities and municipal buyers who need origin documented on the submittal can list it as such.
