Blackburn PGH49 – Frequently Asked Questions
1) What conductor sizes does the Blackburn PGH49 hot tap clamp take on the run and the tap?
The PGH49 parallel groove hot tap clamp covers a tap range of 3/0 to #6 ACSR and up to 4/0 stranded AWG. That range is the deciding spec: if your tap conductor falls outside 3/0 to #6 ACSR or larger than 4/0 stranded, this clamp is not the right body.
2) What voltage is the Blackburn PGH49 tap clamp rated for?
35 kV. That covers typical distribution primary work, so line crews using it for hot taps on overhead distribution are within the rating.
3) Is the Blackburn PGH49 clamp aluminum or copper bodied, and can I use it on a copper-to-aluminum tap?
The PGH49 body is aluminum. Aluminum parallel groove clamps of this style are the standard choice for aluminum and ACSR overhead conductors; for a copper tap onto aluminum run, confirm the connector you pick is rated for both metals before you make the connection.
4) How much room does the Blackburn PGH49 clamp need on the line?
It measures 3-5/16 x 6-5/16 x 2-7/16 inches. Worth checking against your working clearance if you are installing hot with sticks and there is other hardware close by on the span.
5) What is a center-bolt parallel groove hot tap clamp used for instead of a compression connector?
A center-bolt parallel groove clamp like the PGH49 is a bolted, mechanical tap: the run and tap conductors lay in parallel grooves and a single center bolt draws the halves together. You use it where you need to make or break a tap without cutting the line, including energized work, and where you do not want to bring a hydraulic press and dies up the pole. A compression connector is the permanent answer when the tap will never be moved.
6) Is the Blackburn PGH49 sold individually or in a box quantity?
Each. The PGH49 is ordered one clamp at a time, so count one per tap point when you are building out a job.
7) What is the exact part number to order for the Blackburn 450-4 OI hot tap clamp?
Blackburn PGH49 is the manufacturer part number. It is the copper parallel groove hot tap clamp described as 450-4 OI.
