Blackburn UPC44SL1 – Frequently Asked Questions
1) What wire range does the Blackburn UPC44SL1 insulated bus connector take?
The UPC44SL1 accepts conductors from 6 AWG up to 350 kcmil across its ports, which is what the 6-350 in the description refers to. That covers typical feeder taps and service splices in that range. It is a mechanical set screw connector, so conductors are landed and torqued rather than crimped.
2) How many conductors can I land on the Blackburn UPC44SL1 power distribution block?
Four ports, so four conductors, on a five terminal insulated bus connector. The usual use is one incoming feeder with taps out, or multiple taps off a common bus in a panel or pull box.
3) Can I use the UPC44SL1 insulated bus connector with copper conductors, or aluminum only?
The body is aluminum. Aluminum-bodied mechanical connectors of this type are the standard choice where you are landing aluminum or mixed aluminum and copper feeders, provided you use the appropriate oxide inhibitor on aluminum conductors per normal practice.
4) What is the voltage rating on the Blackburn UPC44SL1?
Rated 4000 V. That puts it well above 600 V branch and feeder work, so it covers standard commercial and industrial distribution as well as higher voltage applications within that limit.
5) Does the UPC44SL1 bus connector come already insulated, or do I need to tape and cover it?
It ships insulated with a PVC cover, so no separate taping or a field-applied boot is needed on the body itself. You still strip and land conductors through the port openings.
6) Where is the Blackburn UPC44SL1 made? I have a Buy American requirement on this job.
Country of origin is the United States. Government, institutional, and federally funded projects that carry domestic sourcing language typically ask for exactly this on electrical connectors.
7) Is the UPC44SL1 a crimp lug or a set screw connector?
Mechanical, not compression. Conductors are secured with screws, so you do not need a hydraulic or battery crimp tool and dies to make it up, and the connections can be re-terminated later if the load changes.
8) Is the Blackburn UPC44SL1 sold individually or in a pack?
Sold each, one connector per unit. Order by the quantity of taps you need; a single UPC44SL1 handles four conductors in the 6 to 350 range.
