Blackburn W20-1AN – Frequently Asked Questions
1) What wire sizes does the Blackburn W20-1AN wedge clamp take?
The W20-1AN is sized for 1/0 through 4 conductor, per the product designation AL AN SERVENTR WDGE CLMP/SLDR 1/0-4. It handles one conductor per clamp, so you need a separate clamp for each phase or neutral run you are tapping.
2) Is this Blackburn wedge clamp rated for medium voltage service entrance work?
It carries a 35 kV voltage rating, which covers typical medium voltage distribution and service entrance applications. It is a bare, uninsulated connector with no insulation material, so the installation has to provide the insulating cover or tape system at that voltage class.
3) Is the W20-1AN aluminum clamp OK on an aluminum service conductor?
Yes. The body is anodized aluminum, so it is intended for aluminum service entrance conductors and avoids the dissimilar metal problem you get putting copper-only hardware on aluminum. It also includes a solder connection per the AL AN SERVENTR WDGE CLMP/SLDR description.
4) How does a wedge clamp connector make its connection compared to a compression lug?
This is a tension type connection: the wedge is driven to force the conductor against the clamp body and hold it mechanically, rather than being crimped with a die tool or bolted. That means no compression tooling matched to a specific die index, but you do need the correct wedge tool for the clamp series and the conductor must fall inside the 1/0 to 4 range.
5) How long is the Blackburn W20-1AN clamp?
12-1/2 inches overall. That length matters when you are working inside a meter socket, pedestal, or handhole, so confirm you have the room along the conductor before you commit to it.
6) Is the W20-1AN sold individually or in a bag?
Sold each. On a three phase plus neutral service you would order four, since each clamp accommodates a single conductor.
7) Where is the Blackburn W20-1AN manufactured?
Mexico. Useful if you are filing country of origin documentation on a government or institutional job.
