Blackburn PAE9999-79 – Frequently Asked Questions
1) Can I use this Blackburn parallel groove clamp on copper conductors?
It is an aluminum-body parallel groove clamp supplied with Contax oxide inhibitor, which is the standard aluminum-to-aluminum arrangement. The aluminum body is what governs here: match it to aluminum conductor within the 336 kcmil to 2/0 range. For a copper run you want a copper or bronze bodied connector instead.
2) Is this a splice connector or a ground clamp for a rod or pipe?
It is a parallel groove clamp, which joins two conductors running side by side, used as a wire or cable compression splice in grounding and bonding work. It does not clamp to a ground rod or a water pipe. For a rod or pipe connection you need a rod clamp or pipe ground clamp instead.
3) What size wrench or socket do I need to install the PAE9999-79 clamp?
It is a bolted connector using a 1/2 inch bolt, so bring a socket to suit that bolt head and torque it to the conductor manufacturer's figure. No crimp tool or die set is involved.
4) How much room do I need around the conductor to fit this parallel groove clamp?
Plan for a body measuring 2-13/16 high by 6 long by 2-13/16 wide in inches. That 6 inch length runs along the conductor, so leave clear span on the line before you cut in, particularly in a congested riser or a crowded ground bus area.
5) Is the Contax on the Blackburn PAE9999-79 already applied, or do I need to add joint compound?
The clamp ships with Contax, Blackburn's oxide inhibiting compound, factory applied. You still wire brush the conductor before seating it so the compound can do its job at a clean surface.
6) Is the Blackburn PAE9999-79 insulated, and can I bury it or use it outdoors?
There is no insulation on the body, it is a bare aluminum bolted connector. Anything exposed after the joint is made has to be covered or guarded to suit the installation, and for a direct-buried or concrete-encased ground you should be using a connector listed for that use.
7) Does the PAE9999-79 come in a box of multiples or singly?
It is sold each, one clamp per unit, so order the exact count of joints you have. Useful when you are pulling material for a fixed number of taps rather than stocking a shop.
8) Where is the Blackburn PAE9999-79 clamp made?
Manufactured in Mexico. That matters if you are filing country-of-origin documentation on a government or institutional job.
