Blackburn PAC345 – Frequently Asked Questions
1) What wire sizes does the Blackburn PAC345 parallel groove clamp take?
The PAC345 is rated for conductors from 1/0 through 8 AWG, and it holds two conductors in its two grooves. Both runs have to fall inside that 1/0-8 range.
2) Can I use an aluminum parallel groove clamp on copper grounding conductor?
Yes, with the PAC345. The body is aluminum but the grooves carry a copper liner, which is what keeps copper conductor from sitting directly against the aluminum. That is the whole reason the copper-lined version exists rather than the plain aluminum one.
3) Can I use this clamp to tap a ground conductor without cutting the main run?
That is what a parallel groove clamp like the PAC345 is for. Both conductors lie side by side in the two grooves and the bolt clamps them together, so the through run stays continuous and the tap conductor is bonded to it. Both conductors need to be within 1/0 to 8 AWG.
4) Is the PAC345 a bolted clamp or does it need a crimp tool?
Bolted. The PAC345 tightens down with a bolt, so an electrician needs nothing more than a wrench or socket, no hydraulic crimper and no die set. That is the practical difference from a compression connector on the same conductor range.
5) What are the dimensions of the Blackburn PAC345 clamp for a tight ground bar enclosure?
The clamp measures 2-7/32 inch height by 1-18/32 inch length by 1-1/4 inch width. Worth checking against your box or handhole before you spec it, since the bolt also needs wrench swing room above the body.
6) Is the PAC345 sold in a bag of multiples or one at a time?
One at a time. The PAC345 parallel groove clamp is sold each, so a job needing a clamp at every tap point gets counted piece by piece rather than by carton.
7) Does the Blackburn PAC345 come with any insulation or cover?
No. It is a bare metal grounding connector with no insulating body or boot, which is normal for grounding and bonding work where the connection is meant to be accessible and inspectable. If the location needs the splice covered, that has to be handled separately.
