Blackburn GP-250 – Frequently Asked Questions
1) What conductor range does the Blackburn GP-250 parallel tap connector take?
The GP-250 is rated for a 250 kcmil through 1/0 main and accepts taps from 250 kcmil down to 6 AWG. That range covers the main run and a smaller branch in the same body, so you can pull a feeder tap off a service conductor without cutting the run.
2) Can I use the Blackburn GP-250 tap connector on copper conductors, or aluminum only?
It's a dual-rated terminal, so it can be used on either copper or aluminum conductors. The body is aluminum with a tin-plated surface, which is what makes the AL/CU rating possible: the plating keeps the aluminum from making direct contact with copper and setting up galvanic corrosion at the joint.
3) Is the Blackburn GP-250 a UL listed connector for an inspected installation?
Yes. The GP-250 carries UL file E9809, which is the reference an inspector or plan reviewer will want on a mechanical tap connector. Country of origin is Mexico if your submittal package needs it.
4) Should I use a parallel tap connector like the GP-250 or a split-bolt on a service tap?
A parallel tap connector like the GP-250 seats both conductors side by side in its own channels and clamps them with set screws, so you can pair a 250 kcmil main with a tap as small as 6 AWG without worrying about the two sizes crushing each other the way they do in a split bolt. Split bolts work best when the two conductors are close in size. For a wide size mismatch on a run you don't want to cut, the parallel tap is the better mechanical fit.
5) Does the Blackburn GP-250 come insulated, or do I need to tape or boot it?
It's a bare mechanical tap connector, sold each. Insulation is not part of the connector, so plan on insulating the completed tap per the installation, typically a tape build-up or a snap-on insulating cover sized to the connector.
6) How many GP-250 connectors do I need for a three-phase tap?
One per conductor. The GP-250 is a single-conductor-pair tap sold individually, so a three-phase tap with a neutral means four of them, and each one handles one main and one tap leg.
