Blackburn TR66 – Frequently Asked Questions
1) What conductor size does the Blackburn TR66 service entrance splice take?
The TR66 is sized for 1/0 ACSR conductor, as called out in the Blackburn part description. It joins two conductors, so it is a straight inline splice, not a tap or a multi-port body.
2) Is the Blackburn TR66 splice aluminum or copper, and can I use it on aluminum service entrance cable?
Aluminum body. The TR66 is built for aluminum service entrance conductor, specifically 1/0 ACSR, which is aluminum strands over a steel core. Do not substitute it for a copper-only connector.
3) Does the TR66 need to be crimped, or can it be tightened with a set screw?
Crimped. It is a compression splice, so you need the proper hydraulic or battery crimp tool and die for the barrel. There are no set screws and nothing to torque.
4) Does the Blackburn TR66 meet ANSI connector standards for utility work?
It passes the requirements of ANSI C119.4, the standard covering connectors for use between aluminum and copper conductors. That is the citation utility and inspection specs usually ask for on a service entrance splice.
5) How long is the Blackburn TR66 splice barrel?
The TR66 measures 4-1/4 inches, which is the figure to check against your available slack and against the space inside a pedestal or splice box before you pull conductor.
6) Does the TR66 splice come insulated, or do I have to tape or sleeve it?
It ships bare, with no insulation on the connector itself. Plan on re-insulating the splice yourself with tape, heat shrink, or a cold shrink sleeve if the application calls for it.
7) Is the Blackburn TR66 sold individually or in a bag?
Sold each. One splice per unit, so order one per conductor joint, which means two per single phase pair and three for a three conductor service drop.
