Blackburn 31315 – Frequently Asked Questions
1) What wire sizes does the Blackburn 31315 pigtail connector take?
The Blackburn 31315 is built for copper conductors in the 2/0 through 4/0 range, which is where most service entrance and large feeder taps land. Outside that range it is the wrong connector, so a 1/0 or smaller run needs a different size in the Color Keyed line.
2) Is the Blackburn 31315 copper only, or can I use it on aluminum conductors?
Copper only. The 31315 is a copper-bodied pigtail connector, so it should be used with copper conductors. For aluminum or mixed copper-to-aluminum terminations you need a connector rated AL9CU or dual rated, not this one.
3) Is the Blackburn 31315 UL listed for electrical work?
Yes, it carries UL file E9809. That is the reference an inspector or spec writer will want when the connector is used on a permitted install.
4) Is the 31315 a compression connector or does it torque down with a set screw?
It is a mechanical connector, not a compression lug, so it is made up with set screws and a torque wrench rather than a hydraulic crimp tool. That is the practical advantage on service work: no die set required and the connection can be opened and re-made.
5) What is a pigtail connector used for versus a straight splice or a lug?
A pigtail connector terminates a large conductor and brings out a short pigtail lead, which is how electricians tap a smaller bonding or branch conductor off a heavy feeder without cutting the main run into two spliced halves. If you simply need to join two conductors end to end, a splice connector is the right part; if you are landing on a bus or breaker pad, use a lug instead.
6) Does the Blackburn 31315 come as a single piece or in a bag of several?
It is sold each, one connector per unit, so order by the count of terminations on the job rather than by package.
7) What is the exact manufacturer part number for the Blackburn 2/0-4/0 copper pigtail connector?
Blackburn part number 31315, part of the Color Keyed line. Country of origin is Mexico.
