Blackburn AMTT20 – Frequently Asked Questions
1) What wire sizes does the Blackburn AMTT20 splice connector accept?
The AMTT20 is rated for conductors from 2/0 through 14 AWG, so it covers a wide spread of branch and feeder wire in one connector. Two ports, one conductor per port, making it a straight splice rather than a multi-tap block.
2) Is the Blackburn AMTT20 pre-insulated, or do I have to tape and boot it after I make up the splice?
It ships with a PVC insulating cover on the connector, so you are not building up tape layers or fitting a separate boot after torquing. The body is black.
3) What voltage can I use the AMTT20 splice connector at?
600 V. That covers standard commercial and industrial branch circuits, panel feeders, and 480Y/277 V distribution work.
4) Is the Blackburn AMTT20 UL listed for inspection on a commercial job?
It carries UL file E9809 and CSA 6591, so it is accepted for both US and Canadian work.
5) Can I use the AMTT20 on aluminum conductors, or copper only?
The connector body is aluminum, which is the usual construction for a dual-rated mechanical splice used on either aluminum or copper conductors. Follow the marking on the connector body for the conductor material and torque values before you make up the joint.
6) Is the Blackburn AMTT20 made in the USA for a Buy American spec?
Country of origin is the United States, which is what a federal or state-funded job with domestic content language will ask for on the submittal.
7) Do I need a crimper or hydraulic tool for the AMTT20, or is it a set-screw splice?
It is a mechanical set-screw type splice, not a compression lug, so it is made up with a hex key or driver and needs no crimp die or hydraulic tool. Order number is AMTT20.
8) What does the offset design on the AMTT20 do for me in a tight box or gutter?
The ports are offset rather than in line, which staggers the two conductors instead of running them straight through on one axis. That helps when you are splicing in a crowded pull box or wireway and need the two runs to enter from different directions.
9) Is the AMTT20 sold individually or in a box of connectors?
Sold each, so you can order the exact count for a splice makeup rather than buying a full carton.
