Blackburn UB4K – Frequently Asked Questions
1) What conductor sizes does the Blackburn UB4K insulated connector kit accept?
The UB4K is a four-terminal insulated connector kit covering conductors from 2 AWG up to 350 kcmil, and it ships with four insulating sleeves. If your feeder taps fall outside that 2-350 range, this kit is the wrong one.
2) Is the Blackburn UB4K rated for 600 volt service work?
Yes. The UB4K connector kit carries a 600 V rating with a 750 A current rating, which puts it in range for typical commercial feeder and service-entrance tap work at 600 V or less.
3) How much room do I need in the enclosure for a Blackburn UB4K connector kit?
Plan the space around 8-1/4 inches long by 6-3/8 inches high for the assembled UB4K. In a tight gutter or a shallow meter can, measure before you commit, since the insulating cover is what usually runs out of room rather than the block itself.
4) Do I need to buy separate insulating covers for the Blackburn UB4K?
No. The UB4K is sold as a kit with four insulating sleeves included alongside the four-terminal set screw connector, so the insulation comes in the box. It is sold each, so one order gets you the complete kit.
5) Is the Blackburn UB4K a set screw connector or a compression lug?
Set screw. The UB4K is a bus set screw connector, so conductors land under screws and no hydraulic crimp tool is needed. If your spec calls for compression terminations, this is not a substitute.
6) Is the Blackburn UB4K made in the USA for a Buy American job?
Country of origin on the UB4K connector kit is the United States, which is what most federally funded and municipal jobs want to see on the submittal.
