Blackburn W201-1 – Frequently Asked Questions
1) What wire sizes does the Blackburn W201-1 service wedge clamp take?
The W201-1 covers No. 1/0 through No. 4 conductor, and it handles one conductor per clamp. If your service drop or tap falls outside 1/0 to 4 AWG, you need a different wedge clamp size in the series, not this one.
2) Is the Blackburn W201-1 wedge clamp rated for medium-voltage work?
It carries a 35 kV voltage rating, so it is suited to medium-voltage service and distribution applications as well as ordinary secondary service drops.
3) Does a service wedge clamp need a torque wrench or bolts to install?
No. The W201-1 is a tension-type connection: the wedge is driven into the body and the conductor tension holds it, so there is no bolt to torque. That is the practical difference between a wedge clamp and a bolted or compression connector, and it is why crews use them for overhead service drops where a quick dead-end is needed.
4) Is the Blackburn W201-1 aluminum clamp safe on copper conductor?
The clamp body is aluminum with a bare, uncoated surface. Aluminum-bodied wedge clamps are intended for aluminum conductor; putting bare aluminum directly against copper in an outdoor overhead location risks galvanic corrosion at the joint. For copper service conductor, specify a connector rated for copper or a dual-rated AL9CU device.
5) How long is the W201-1 wedge clamp, and will it fit in a tight rack or pole-top space?
Overall length is 12-1/2 inches. That is a long assembly by connector standards, so allow that much clear run between the dead-end point and the first support or insulator when you lay out a pole-top or rack termination.
6) Does the Blackburn W201-1 come insulated or do I need to cover the connection?
There is no insulation on this clamp; the body is bare aluminum with no jacket or boot. Any required insulating or covering at the connection has to be added separately with tape, a cover, or a shrink sleeve per your utility's or the job's standard.
7) Is the W201-1 sold each or in a box quantity?
It is sold as each, one clamp per unit, so order one per conductor you are terminating. A three-phase dead-end at 1/0 through 4 AWG means three clamps.
8) Where is the Blackburn W201-1 manufactured?
Country of origin is Mexico. That matters for buyers with domestic-content or trade-documentation requirements on utility and government work, so check it against your project's sourcing clause before you standardize on it.
