Blackburn W40-1AN – Frequently Asked Questions
1) Can I use an aluminum wedge clamp on copper service conductors, or only aluminum?
The W40-1AN body is anodized aluminum with a bare surface finish. Blackburn's AN suffix on this service wedge clamp line denotes the aluminum, non-insulated version intended for aluminum service entrance conductors. If your run and tap are copper, specify a connector rated for copper rather than this one.
2) What voltage is the Blackburn W40-1AN wedge clamp rated for?
Rated to 35 kV, so it covers secondary service work and medium-voltage distribution taps up to that class. That rating is for the connector itself; the conductors and any separate insulating cover have to carry their own rating for the circuit.
3) Does this wedge clamp come insulated or do I need to cover it?
It ships bare. The insulation material on the W40-1AN is listed as none and the finish is bare anodized aluminum, so any insulating or protective cover for the completed tap is a separate item you order alongside it.
4) How does a wedge clamp connector attach compared with a bolted split-bolt or a compression connector?
This one is a tension connection. The wedge is driven to clamp the run and tap conductors together under spring tension rather than being torqued down like a split bolt or crimped like a compression sleeve. That means no torque wrench and no die set, but you do need the matching driving tool for the wedge system. Choose a compression or split-bolt connector instead if your spec calls out a crimped or bolted joint.
5) How much room do I need in the enclosure or on the pole for this Blackburn clamp?
Plan for 12-3/4 inches of length. That is the stated overall size of the W40-1AN, so measure the available run between the service head and the terminations before committing to it in a tight weatherhead or meter can.
6) Is the Blackburn W40-1AN sold individually or in a bag?
Sold each. One clamp per unit, so order one per tap you are making rather than expecting a contractor pack.
7) What is the exact part number and where is this Blackburn clamp made?
Manufacturer part number W40-1AN from Blackburn, an aluminum service wedge clamp made in Mexico. Use that MPN when matching what is already installed on a service, since the numbering within the W-series changes with conductor range.
