Blackburn PAA493 – Frequently Asked Questions
1) What wire sizes does the Blackburn PAA493 parallel groove clamp take?
The PAA493 is built for conductors in the 1/0 through 6 range, as called out in the part description (1/0-6). It holds two conductors, one in each groove, so it is a two-wire tap or splice connector rather than a multi-run body.
2) Is the Blackburn PAA493 clamp aluminum or copper bodied, and can I use it on copper wire?
The body is aluminum. Aluminum-bodied parallel groove clamps in this family are the standard choice for aluminum-to-aluminum and aluminum-to-copper connections where the clamp is listed for dual rating; for straight copper-to-copper grounding work many electricians specify a bronze or copper-alloy clamp instead. Confirm the conductor metals on your drawing against the marking on the body before you torque it down.
3) What size wrench or socket do I need to install the PAA493?
The clamp uses a 3/8 inch bolt with a 9/16 inch head, so a 9/16 inch socket or box wrench is what goes in the pouch. It is a bolted connection, no crimp tool or die set required, which is why crews use this style for field taps and repairs where a hydraulic press is not practical.
4) How much room does the PAA493 parallel groove clamp need in a pull box or handhole?
Body dimensions are 2-7/32 inch height by 1-3/16 inch length by 1-1/2 inch width, and you need swing room above that for a 9/16 inch socket on the bolt head. In a congested handhole or ground bar enclosure, lay it out so the bolt faces the open side.
5) Should I use a bolted parallel groove clamp or a compression connector for a ground tap?
A bolted parallel groove like the PAA493 is the one to reach for when you want the connection to be reworkable, you are splicing in the field, or you do not have a crimp tool on site. Compression connectors are the choice when the connection is direct-buried, encased, or has to be irreversible. The PAA493 covers the wire-or-cable splice application with a single 3/8 inch bolt and handles two conductors.
6) Does the Blackburn PAA493 come with any insulating cover or boot?
No cover comes with it. The PAA493 is a bare aluminum clamp with no insulation material, so if the tap needs to be insulated you are adding a separate cover or tape wrap as part of the job.
7) Is the Blackburn PAA493 sold individually or in a box quantity?
It is sold each, one clamp per unit, so if you are laying out a ground grid or a run of taps just order the piece count you need rather than working back from a carton quantity.
8) What is the manufacturer part number for the Blackburn aluminum parallel groove clamp for 1/0-6 wire?
Blackburn PAA493 is the part number, a one-bolt aluminum parallel groove clamp rated for two conductors in the 1/0 through 6 range. Country of origin is India.
