Blackburn UPC30SL – Frequently Asked Questions
1) What wire sizes does the Blackburn UPC30SL insulated bus connector take?
The UPC30SL is rated for conductors from 12 AWG up to 4 AWG, so it covers everything from branch circuit wire through a small feeder tap in the same block. All three ports work within that same 12-4 range.
2) How many conductors can I land in a Blackburn UPC30SL power distribution block?
Three. The UPC30SL is a 3 terminal, 3 port block, so you get three separate wire positions on the bus. If you need to feed more than three taps off one point, you need a larger port count rather than doubling conductors into a port.
3) Is the Blackburn UPC30SL connector aluminum or copper bodied, and can I use it on copper wire?
The body is aluminum. Aluminum mechanical connectors of this style are commonly listed AL9CU for both aluminum and copper conductors, but confirm the marking stamped on the block itself before mixing metals on a job.
4) Does the Blackburn UPC30SL come insulated, or do I have to tape or boot it?
It ships insulated. The UPC30SL is an insulated bus connector, so the cover is part of the product and you are not wrapping the block after termination. That matters where the splice sits inside a panel or a junction box with live parts nearby.
5) Is this a set screw mechanical lug or a compression connector?
Mechanical. The UPC30SL is a mechanical connector, which means conductors are clamped with set screws and torqued down rather than crimped with a hydraulic tool. For an electrician doing service work or a maintenance crew without a crimper on the truck, that is the practical difference.
6) Is the Blackburn UPC30SL sold individually or in a pack?
Each. The selling unit is a single connector, so a three way tap job takes one piece. Buyers standardizing a facility on one distribution block can order exact counts rather than round up to a carton.
7) Where is the Blackburn UPC30SL made? We have domestic sourcing requirements.
United States. For government, healthcare, and institutional procurement working to domestic content rules, the UPC30SL is US origin.
