Thomas & Betts W20-1 – Frequently Asked Questions

1) What wire sizes does the Thomas & Betts W20-1 wedge clamp take?
The W20-1 aluminum service wedge clamp is built for 1/0 through 4 AWG conductors, one conductor per clamp. If your service drop or entrance conductor falls outside that range, this is the wrong clamp and you want a different wedge size in the series.
2) Can I use an aluminum wedge clamp on copper conductors?
The W20-1 body is aluminum with a bare finish, no plating and no insulation. Aluminum-to-copper contact in an outdoor or damp service location is where galvanic corrosion starts, so for copper runs electricians normally specify a tin-plated or dual-rated connector instead. On aluminum service conductors this clamp is the intended pairing.
3) Is a 35kV connector overkill for a 120/240V service drop?
No. The 35 kV rating on the W20-1 is the insulation class of the system it may be applied on, not a minimum. A connector rated to 35 kV is fine on a 600V or residential service; the rating just means it is also acceptable on medium-voltage distribution work.
4) What does a tension connection mean on a service wedge clamp, and do I need a torque wrench?
Tension type means the wedge is driven into the shell and the conductor is gripped by the mechanical tension of that wedge, rather than by a torqued setscrew or a compression die. That's the appeal on service entrance work: no crimp tool, no torque spec to chase, the grip tightens as the conductor pulls.
5) Does the W20-1 come insulated or do I have to cover the connection myself?
It ships bare. Insulation material is none and the finish is bare aluminum, so any covering the job calls for, tape, a boot, or a shrink sleeve, is a separate line item on your order.
6) Is the W20-1 a splice connector or a tap connector?
It's a service entrance wedge clamp, used to terminate or tap a single conductor at the service point, one conductor to the clamp. It is not a two-run parallel splice and not a compression sleeve for joining two conductors end to end. For joining two cable ends, look at a compression splice sized to the conductor instead.
