Blackburn HLC3974AP9BT-1 – Frequently Asked Questions
1) What conductor sizes does the Blackburn HLC3974AP9BT-1 hot line clamp take?
The HLC3974AP9BT-1 covers 3/0 through #6 ACSR and 4/0 through #6 solid AWG. That range spans typical overhead distribution runs down to small taps, so one clamp part number covers a lot of the line work on a feeder without going back to the truck for a second size.
2) What voltage can this Blackburn hot line clamp be used on?
Rated 35 kV, so it suits primary distribution work up through 35 kV class. Do not carry it above that rating.
3) Is the HLC3974AP9BT-1 aluminum or copper, and can I land a copper conductor in it?
The clamp body is aluminum with a tin-plated finish. Tin plating is what makes it dual rated in practice: it isolates the aluminum from copper so you can tap a copper conductor without the galvanic corrosion you would get at a bare aluminum-to-copper joint.
4) What does the back tap on this hot line clamp do for me?
The back tap gives you a second conductor port on the rear of the clamp, so the clamp lands on the energized line and the tap conductor terminates at the back rather than sharing the main groove. It is what you want when you are pulling a service or equipment tap off an existing hot line without cutting it.
5) Can I use a hot line clamp like this for a system ground or bonding connection instead of a ground clamp?
No. This is a hot-line tap clamp for making a connection onto an energized overhead conductor, not a grounding electrode or pipe-bonding clamp. If you need to bond to a water pipe, rod or rebar, use a purpose-built ground clamp sized to the electrode; the eye-screw geometry here is made to be set and removed with a hot stick on a line conductor.
6) What does "protected thread" mean on a hot line clamp like the HLC3974AP9BT?
It is a hot-line clamp built with the eye screw threads shielded, so grit, ice and corrosion do not seize the screw between installations and the clamp still runs freely when you go to open or close it with a hot stick. On overhead work where clamps sit outdoors for years, that is the difference between reusing the clamp and cutting it off.
7) Is this hot line clamp sold individually or in a box?
Selling unit is each, one clamp per order line, so line crews and utility storerooms can order exact counts rather than a fixed carton. Country of origin is India.
