Blackburn W20-1B – Frequently Asked Questions
1) What conductor sizes does the Blackburn W20-1B wedge clamp take?
The W20-1B is a service entrance wedge clamp sized for 1/0 through 4 conductor, run to service drop. It handles one conductor per clamp, so a three-wire drop needs three clamps.
2) Is the W20-1B clamp rated for medium voltage service?
It carries a 35 kV rating, so it covers secondary service drop work and up through medium voltage applications at that class.
3) Does the Blackburn W20-1B come insulated or do I need to cover it?
Bare, with no insulation on the clamp body. The finish is iridited aluminum left bare, so any insulating or covering on an energized installation has to be added separately.
4) Can I use an aluminum wedge clamp on copper service conductors?
The W20-1B body is iridited aluminum. The iridite conversion coating is the corrosion treatment aluminum connectors get for outdoor service work; for copper-to-aluminum contact, the usual practice is to apply an oxide inhibiting joint compound at the connection. Aluminum-bodied clamps like this one are standard on aluminum triplex and quadruplex drop.
5) How much room do I need to mount a W20-1B service wedge clamp?
Plan for a 12-1/2 inch length and 2-3/8 inch depth. On a crowded weatherhead or meter socket entrance, that length is the dimension that decides whether three clamps will sit side by side without crowding.
6) Is the W20-1B a bolted lug or a tension type connector?
It is a tension type connection. The wedge is driven into the clamp body and the pull on the conductor keeps the joint tight, rather than relying on a torqued set screw or bolt.
7) Is the Blackburn W20-1B sold individually or in a box?
Sold each. Order one per conductor you are terminating, so a typical three-conductor service drop takes three.
8) Where is the Blackburn W20-1B manufactured?
Manufactured in Mexico. Useful if your utility, municipal, or federal job carries a country of origin reporting requirement.
