Blackburn UPC44SLWL2P – Frequently Asked Questions
1) What is the Blackburn UPC44SLWL2P insulated bus connector used for?
The UPC44SLWL2P is an insulated multi-tap bus connector, also called a power distribution block, used to split one feed into several branch conductors inside a panel, meter socket, or junction enclosure. It is a mechanical set screw connector, so conductors are landed and torqued rather than crimped or soldered, and the body comes pre-insulated so no separate taping or heat shrink is needed over the block.
2) How many conductors can the Blackburn UPC44SLWL2P bus connector accept?
Five terminals total with four ports, per the UPC44SLWL2P designation. In practice that gives you a main feed landing plus four tap positions off the same bar, which is what you want when one supply has to serve several branch runs from a single point.
3) What wire sizes does the Blackburn UPC44SLWL2P take?
The UPC44SLWL2P is a 12-4 range connector, meaning it accepts conductors from #12 AWG up through #4 AWG. If your feeder is larger than #4, this block is not the right part and you need a larger-range Blackburn power distribution block.
4) Is the Blackburn UPC44SLWL2P aluminum or copper bodied, and can I land aluminum conductors in it?
The body is aluminum. Aluminum-bodied mechanical connectors of this style are the standard choice for dual-rated work where either aluminum or copper conductors may be landed, and aluminum conductors should be wire brushed and treated with an oxide inhibitor before landing and the set screws torqued to the value marked on the connector.
5) Do I need to insulate or tape over the Blackburn UPC44SLWL2P after landing the wires?
No taping of the block itself. The UPC44SLWL2P ships insulated, with a molded cover over the bar and open ports only where the conductors enter. That is the reason to choose it over a bare bus bar in a crowded enclosure where a stray strand or a dropped tool could find a live bar.
6) Is the Blackburn UPC44SLWL2P made in the USA for jobs with domestic sourcing requirements?
Country of origin on the UPC44SLWL2P is the United States, which matters on federal, state, and institutional work carrying domestic preference language in the spec.
7) What part number should I order to match an existing Blackburn insulated power distribution block on 12-4 conductors?
The manufacturer part number is UPC44SLWL2P. That exact number gets you the 5 terminal, 4 port, 12 AWG to 4 AWG insulated block in aluminum. Nearby Blackburn UPC numbers change port count and wire range, so match the full suffix rather than just the UPC prefix when you are standardizing a panel.
8) Is the Blackburn UPC44SLWL2P sold individually or in a multi-pack?
It is sold each, one connector per unit, so order the quantity you need for the job rather than by box or carton.
