Blackburn GP-250WC – Frequently Asked Questions
1) What conductor sizes does the Blackburn GP-250WC parallel tap connector take?
The GP-250WC is built for a 250 kcmil main run with a 1/0 tap, per the product designation MAIN250-1/0. If your main is larger than 250 kcmil or your tap is smaller than 1/0, you need a different range in the GP series rather than this one.
2) Is the Blackburn GP-250WC rated for aluminum conductors or only copper?
The body is aluminum, which is the standard construction for a mechanical tap connector used on aluminum service and feeder conductors. It is a mechanical connector, so conductors are clamped under a setscrew rather than crimped or welded.
3) Does the Blackburn GP-250WC come with an insulating cover, or do I order that separately?
The cover is included, which is what the CVR in the part description refers to. You do not need to add a separate insulating boot to get an insulated tap.
4) Can I use the GP-250WC parallel tap on a 480 volt feeder?
Yes. The GP-250WC carries a 600 V rating, which covers 120/208, 277/480 and any other common low-voltage distribution system up to 600 volts.
5) What conductor temperature rating does the Blackburn GP-250WC support?
It is rated to 90 C (194 F), so it will not limit a 90 C insulated conductor such as THHN or XHHW-2 at its termination.
6) Do I need a splice block or will a parallel tap connector work for tapping a feeder without cutting it?
A parallel tap connector is the right choice when the main conductor stays continuous and you are pulling a tap off it, such as feeding a submeter, a disconnect, or a panel from an existing run. Use a splice reducer or multi-tap block instead when you are cutting the main, or when you need several taps off one point. The GP-250WC handles a single 1/0 tap off a 250 kcmil main.
7) How is the Blackburn GP-250WC sold, each or in bags?
Sold individually, each. For a three-phase tap you will need three of them, plus one more if you are also tapping a neutral.
8) What color is the cover on the Blackburn GP-250WC, and does it help identify the size in the field?
The cover is red. Blackburn colour codes the GP covers by connector range, so a red cover on a pull box tells a service tech at a glance that the tap is the 250 kcmil main / 1/0 tap size.
