Blackburn HLC39749 – Frequently Asked Questions
1) What conductor sizes does the Blackburn HLC39749 hot-line clamp accept?
The HLC39749 takes a main run up to 4/0 stranded AWG and a tap down to #6 solid AWG. That range covers most distribution main line conductors with a smaller tap lead, so check both your run and your tap fall inside 4/0 STR and #6 SOL before ordering.
2) What voltage is the Blackburn HLC39749 hot-line clamp rated for?
Rated to 35 kV, so it suits primary distribution taps at 15 kV, 25 kV and 35 kV class. Don't apply it above that class rating.
3) Is the HLC39749 hot-line clamp bronze or aluminum, and can I use it on copper conductor?
It's a bronze body clamp, which is the material lineworkers use for copper main and tap conductors. Bronze also holds up outdoors on overhead distribution lines.
4) What does "protected thread" mean on this Blackburn hot-line clamp?
The HLC39749 is a protected-thread hot-line clamp, meaning the eye bolt threads are shielded from weather and arc debris so the clamp can still be operated with a hot stick after years in service. That's the practical difference from an unprotected-thread clamp, which can seize up on the line.
5) Should I use a hot-line clamp or a compression tap for an overhead distribution connection?
A hot-line clamp like the HLC39749 is the choice when the tap needs to be installed or removed from an energized line with a hot stick, or when the connection has to be opened again later for switching or maintenance. A compression tap is permanent and needs the line de-energized or a different work method. For a temporary or re-openable 35 kV tap, the hot-line clamp is the right part.
6) Is the Blackburn HLC39749 sold individually or in a box?
It ships as an each, one clamp per unit, so line crews and utility storerooms can order exact quantities per pole or per tap rather than a fixed carton.
7) What is the manufacturer part number for the Blackburn bronze 400-6 hot-line clamp, and where is it made?
The part number is HLC39749 from Blackburn, described as a bronze hot-line clamp for 400-6 range, and it is manufactured in India.
