Blackburn AMTD250104 – Frequently Asked Questions
1) What wire sizes does the Blackburn AMTD250104 multi-tap connector accept?
The AMTD250104 is rated for conductors from 250 kcmil down to 10 AWG in each port, so one connector covers a feeder tap down to small branch conductors without changing lugs. Every port on the block takes that same 250-10 range.
2) How many conductors can I land on this Blackburn 4-port tap connector?
It is a four-port block with ports on both sides, so you land four conductors per side, eight total. That is the layout you want for a straight-through tap where line conductors come in one face and taps leave the other, rather than a one-sided block where everything enters from the same direction.
3) What is the voltage rating on the Blackburn AMTD250104, and can I use it in a 480V panel?
Rated 600 V, which covers 120/208, 277/480 and 600 V systems. It is a power distribution tap block for service and feeder work inside enclosures, gutters and pull boxes at those voltages.
4) Is this multi-tap connector UL listed for inspection sign-off?
Yes. The AMTD250104 carries UL file E9809 and CSA 6591, so it is accepted on both sides of the border for power distribution taps. Those are the file numbers to cite if an inspector asks for listing evidence.
5) Can I use an aluminum multi-tap connector like this on copper conductors?
The AMTD250104 body is aluminum, and aluminum-bodied mechanical connectors in this class are the dual-rated AL/CU type used on both aluminum and copper conductors. Aluminum is the standard body material for feeder tap blocks in gutters and pull boxes because it handles aluminum conductors without a dissimilar-metal problem.
6) Do I need to add insulating covers or tape when I install a multi-tap connector like this?
The AMTD250104 ships as an uninsulated black aluminum block, sold each, with no cover included. In an accessible enclosure you either install it inside an approved gutter or box, or add a separate insulating cover or tape system to keep live parts guarded. Budget for that separately when you order.
7) Is the Blackburn AMTD250104 made in the USA for Buy American projects?
Country of origin is the United States, which is what federal, state and institutional jobs with domestic-content language on electrical materials usually require documented. The part number to reference on the submittal is AMTD250104.
8) When should I use a both-side multi-tap block instead of separate split-bolt or single-port lugs?
Use a both-side four-port block like the AMTD250104 when you are splitting one feeder into several taps in a gutter or pull box and want the terminations organized and re-enterable. Split bolts and compression lugs are one-shot connections per pair of conductors; this block handles up to four in and four out on a single 600 V rated body, with each port taking 250 kcmil to 10 AWG.
