Blackburn W20-1FC – Frequently Asked Questions
1) What conductor sizes does the Blackburn W20-1FC wedge clamp take?
The W20-1FC is a service entrance wedge connector built for 1/0 through 4 conductor, single conductor per clamp. It is a one-conductor device, so each run needs its own clamp.
2) Is the Blackburn W20-1FC rated for medium voltage service work?
It carries a 35 kV voltage rating, which covers primary and secondary service entrance work well past typical 600V utilization circuits.
3) Is the Blackburn W20-1FC insulated, or do I need to cover it after install?
It ships bare aluminum with no insulation on the body. Any covering, tape, or shrink boot for the finished splice has to be ordered separately.
4) Does the W20-1FC wedge clamp need a torque wrench or crimper to install?
No. It is a tension type connector, a wedge driven into the sleeve to hold the conductor mechanically. No crimp die, no bolt torque spec, no soldering.
5) Can I use an aluminum wedge connector like the W20-1FC on copper conductor?
The W20-1FC body is aluminum. Aluminum-bodied service wedge connectors are commonly dual rated AL/CU, but this one is published only as aluminum, so treat it as an aluminum-conductor connector unless your spec says otherwise. If the job calls out copper-only hardware, source a connector stamped for that service.
6) How long is the Blackburn W20-1FC wedge clamp assembly?
It measures 18-1/2 inches in length with a flexible depth, so it is a tail-style service entrance clamp rather than a compact inline sleeve. Allow for that length in the weatherhead or pedestal you are working in.
7) Is the W20-1FC sold individually or in a bag?
Sold each. Since the clamp handles one conductor, a three-phase or multi-conductor service needs one per leg.
8) What is the manufacturer part number for the Blackburn aluminum service wedge clamp for 1/0-4 conductor?
Blackburn W20-1FC. That is the ordering number to give a distributor, made in Mexico.
