Blackburn W40-1BFC – Frequently Asked Questions
1) What is the Blackburn W40-1BFC wedge clamp used for?
It's a service entrance wedge connector in iridited aluminum, used to tap or splice a single conductor at the service entrance. The wedge is driven to hold the conductor under tension rather than by a bolt or set screw, so the connection is mechanical and permanent. It handles one conductor per connector and is sold each.
2) Can I use the W40-1BFC on a medium voltage run, or is it service entrance only?
The W40-1BFC carries a 35 kV voltage rating, so it is not limited to low voltage service drops. Bear in mind it comes with no insulation of its own, bare finish, so any cover, boot, or insulating detail has to be supplied separately as part of the installation.
3) Is the W40-1BFC a bolted connector I can take apart later?
No. It's a tension-type wedge connector, meaning the wedge is driven to compress the conductor against the C-body. That is a permanent connection, not a reusable bolted lug. If you need a termination you can loosen and re-land, order a bolted mechanical connector or a set screw lug instead.
4) Does the Blackburn W40-1BFC work on aluminum conductors as well as copper?
The body is iridited aluminum. The iridite chromate treatment on aluminum bodies is what lets a connector be used on aluminum conductors without the bare-aluminum oxidation problem, and aluminum-bodied connectors of this kind are the standard choice for aluminum service conductors. For any aluminum termination, brush and apply oxide inhibitor to the conductor before the wedge is driven.
5) How much room do I need in the handhole or pedestal for this wedge connector?
Plan for 18-1/2 inches of length. The stated size is length 18-1/2 in with flexible depth, so the assembly needs a clear straight run of that much conductor and space; depth is not a fixed dimension because the connector follows the cable.
6) Can I land two conductors in one Blackburn W40-1BFC?
No, it takes one conductor. The connector is rated for a single conductor, so a second tap needs its own wedge connector on the run.
7) What is the exact part number and who makes the W40-1BFC wedge connector?
Blackburn is the manufacturer and the part number is W40-1BFC, ordered as a single piece. Country of origin is Mexico.
