Blackburn GP-2WC – Frequently Asked Questions
1) What wire sizes does the Blackburn GP-2WC parallel tap connector take on the main and on the tap?
The GP-2WC accepts 2 through 12 AWG on the main run and 4 through 14 AWG on the tap. That combination covers most branch takeoffs from a feeder or a service conductor, but if your main run is larger than 2 AWG you need a bigger frame size.
2) Can I use the Blackburn GP-2WC on both aluminum and copper conductors?
Yes. It is a dual-rated terminal, so it is listed for aluminum and copper conductors, including an aluminum main with a copper tap. The body is aluminum with a tin plated surface, which is what makes the copper contact acceptable and slows galvanic corrosion at the aluminum interface.
3) Does the GP-2WC come with an insulating cover, or do I have to buy that separately?
The cover ships with it. The GP-2WC is the covered version of the parallel tap connector, so you get the connector and its insulating cover as one item, sold each. No separate cover or tape wrap purchase is needed to insulate the splice.
4) Do I need to cut the main conductor to tap it with this connector?
No. A parallel tap connector like the GP-2WC lands the main conductor and the tap conductor side by side in the same body, so the main run stays continuous. That is the difference between this and a butt splice or a pigtail: you break out a branch without interrupting the feeder.
5) Is one GP-2WC enough for a three phase tap, or do I need more?
One GP-2WC handles one conductor pair, a single main and a single tap. For a three phase takeoff you need one per phase, plus another for the neutral if you are tapping that too, and each comes with its own cover since the unit of sale is each.
6) What should I use instead if my tap wire is smaller than 14 AWG or my main is larger than 2 AWG?
The GP-2WC is out of range in both of those cases. Its window is 2 to 12 AWG main and 4 to 14 AWG tap, and a conductor outside that range will not seat and torque correctly. Move up to a larger frame parallel tap for heavier mains, or to a mechanical connector or insulated tap rated down to the smaller gauge for control sized tap wire.
7) Is the Blackburn GP-2WC suitable for direct burial or wet locations?
Nothing in the GP-2WC's published data covers burial or submersion ratings, so treat it as a standard covered parallel tap for enclosure, pull box, and gutter work. For buried or submerged splices use a connector specifically listed for direct burial along with a sealed splice kit.
8) Where is the Blackburn GP-2WC made, and what is the exact part number to order?
Order it as Blackburn GP-2WC. It is manufactured in Mexico and sold as a single piece, metallic in appearance with a tin plated aluminum body. Distributors matching against a bill of materials should note the GP-2WC suffix is the covered variant.
