Blackburn WRS172 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WRS172 stirrup connector take?
The WRS172 is rated for run conductors from 1/0 through #3, with the stirrup bail sized for 1/0 stranded AWG. It is a compression connector, so the run is crimped rather than bolted, and the wire size range is the first thing to confirm against the service drop or tap you are terminating.
2) Can I use an aluminum stirrup connector on copper conductors?
The WRS172 body is aluminum with tin plated copper bails. The tin plated copper bail is what the hot line clamp grabs, so the stirrup itself takes a copper connection, while the compression barrel on the run is aluminum bodied. Check the connector's own listing marking for the conductor metal you are crimping before you set the die.
3) Is the Blackburn WRS172 insulated, or do I need to cover it after crimping?
No insulation on the WRS172. Insulation material is listed as none, so it is a bare connector. If the application needs covering, you specify separate insulating covers or tape; nothing of that sort comes with the connector.
4) What is a stirrup connector for, and why not just clamp onto the conductor itself?
A stirrup gives a hot line clamp a dedicated, sacrificial point of attachment. You crimp the compression connector onto the run once, and every future temporary or metered connection lands on the tin plated copper bail instead of biting into the main conductor. That keeps the run undamaged through repeated clamp-ons, which is why utilities and service crews use them on drops rather than clamping direct.
5) How much room do I need in the enclosure or on the pole for the WRS172?
Size is given as 10 x 2-15/16 inches. That is a long body for a compression connector, so plan the clearance around the crimp barrel and the bail before you commit to a location, particularly inside a pedestal or a crowded gutter.
6) Do I need a compression tool for the Blackburn WRS172, or can it be tightened with a wrench?
It is a compression connector, not a mechanical set screw type, so it has to be crimped with a die-type compression tool. No wrench-tightened path. Match the die to the barrel and the conductor size in the 1/0 through #3 range before crimping, because a compression joint cannot be backed off and redone.
7) Is the Blackburn WRS172 sold individually or in a box?
Sold each. The selling unit of measure on the WRS172 is a single connector, so if you are landing stirrups on multiple phases you order one per connection point.
8) Where is the Blackburn WRS172 made?
Country of origin on the WRS172 is Mexico. That is the detail institutional and government buyers usually need for domestic-preference paperwork on an electrical submittal.
