Blackburn ATC 3 TN – Frequently Asked Questions
1) Is the Blackburn ATC 3 TN tap connector a compression fitting or a mechanical set-screw type?
It's a compression connector. The ATC 3 TN is crimped with a compression tool and die, not tightened with a set screw, so once it's crimped the joint is permanent. That also means you need the matching die for the connector before you get on the ladder, since there's no way to install it with hand tools alone.
2) Can the Blackburn ATC 3 TN be used on aluminum conductors, or copper only?
It's an aluminum tap splice, tin-plated, and the tin plating is what lets it be used on either aluminum or copper conductors without a dissimilar-metal problem at the contact surface. Standard practice on aluminum is to wire brush the conductor and apply an oxide-inhibiting compound before crimping.
3) How many wires does the ATC 3 TN compression splice take?
Two conductors, a run and a tap. It's a tapered two-conductor splice, so it isn't the part for gathering three or more wires into one connection. For a multi-conductor gathering point you want an H-tap or a multi-port compression connector instead.
4) Does the Blackburn ATC 3 TN come insulated, or do I have to tape or shrink it?
It ships bare, with no insulation on the barrel. Any covering is up to the installer, so plan on tape, a shrink sleeve, or an insulating cover as part of the job if the splice is going anywhere it can be contacted or where it needs environmental protection.
5) What standard does the Blackburn ATC 3 TN tap connector meet?
ANSI C119.4, the standard covering connectors for use between aluminum and aluminum or aluminum and copper conductors. That's the reference a spec or submittal will usually call out for a compression tap on a distribution or service connection.
6) Is the Blackburn ATC 3 TN made in the USA for a Buy American job?
Country of origin is the United States, which is what most public-works and federally funded jobs want documented on electrical connectors. Order it by manufacturer part number ATC 3 TN so the submittal matches what shows up on site.
