Blackburn UPC66SL – Frequently Asked Questions
1) What wire sizes does the Blackburn UPC66SL insulated power distribution block accept?
The UPC66SL takes conductors from 4 AWG through 500 kcmil in each of its six ports. That range covers feeder taps and service entrance work where you are splitting one large conductor into multiple smaller runs, as long as every conductor landed falls inside 4 to 500.
2) How many conductors can I land on a Blackburn UPC66SL bus connector?
Six. The UPC66SL is a 6 terminal, 6 port insulated bus connector, so you get six separate wire ports for tapping or splicing. If you need more terminations than that on one bus, you need a larger multi-port block rather than doubling conductors into a port.
3) Is the Blackburn UPC66SL connector aluminum or copper body, and can I use it on copper conductors?
The body is aluminum. Aluminum mechanical connectors of this style are dual rated for copper and aluminum conductors, and the listed dual rating on the connector itself is what governs, so verify the rating stamped on the block before landing copper.
4) Does the UPC66SL come with an insulating cover or do I have to buy one separately?
It is an insulated bus connector, so the insulating housing is part of the unit, not a separate accessory. That is what makes it suitable for mounting inside a panel or enclosure where exposed bus would otherwise need a barrier.
5) Is the Blackburn UPC66SL a mechanical set screw connector or a compression lug?
Mechanical. Terminations are made with set screws, so it installs with a hex driver or torque wrench and needs no crimp tool or die set. Torque each screw to the value marked on the block.
6) What is the Blackburn part number I should quote for a 6 port insulated 4 to 500 bus connector?
UPC66SL is the catalog number, and it is also the manufacturer part number. Quote it as Blackburn UPC66SL, 6 terminal, 6 port, 4 to 500 range, insulated.
7) Is the Blackburn UPC66SL sold individually or in a multi pack?
Each. One UPC66SL insulated 6 port bus connector per unit ordered, so order one per bus or phase you are terminating. A three phase plus neutral distribution point takes four.
8) Where is the Blackburn UPC66SL made?
United States. That matters on federally funded and Buy American specified jobs, where domestic origin on electrical connectors is often a submittal requirement.
