Blackburn VGC4040 – Frequently Asked Questions
1) What wire sizes does the Blackburn VGC4040 parallel groove connector take?
The VGC4040 Vicelock parallel groove connector covers a 1 through 4/0 conductor range, so one part handles taps and runs anywhere in that band. It is a mechanical connector, tightened down on the conductors rather than crimped, so no die set or hydraulic tool is needed to make the connection.
2) Can I use one VGC4040 to tap two different size conductors, say a 4/0 run and a #1 tap?
Yes. A parallel groove connector clamps two conductors side by side, and the VGC4040 is rated across 1 to 4/0, so a 4/0 main with a #1 tap sits within the range of the single connector. Both conductors must fall inside that 1 to 4/0 band.
3) Is the VGC4040 connector suitable for direct burial or a ground grid?
It is a bronze-bodied mechanical connector, which is the material normally specified for buried and grounding-electrode work because it resists corrosion in soil and mates well with copper conductors. Bare metal, with no insulation on the body, so anything you cover it with is up to your own taping or boot detail.
4) Does the Blackburn VGC4040 come insulated or do I need to tape it?
Uninsulated. The Vicelock parallel groove connector ships as a bare bronze body with no insulating cover, so if the splice is in a location that needs to be insulated you will have to tape it or add a separate cover.
5) How much space does the VGC4040 need inside a box or enclosure?
Figure on a 9/16 inch outside diameter for the connector body, plus room for a wrench on the bolt and for the two conductors entering parallel. Tight pull boxes and crowded ground bars are where people get caught out, so check the clearance before you commit to the location.
6) Do I need a crimping tool for the Blackburn Vicelock parallel groove connector?
No. It is a mechanical connector, made up with a wrench on the clamping bolt, which is why crews use this style for field splices and grounding taps where dragging a hydraulic crimper and the right die is impractical. Compression lugs and splices are the alternative when a permanent, tool-verified crimp is called for on the spec.
7) Is the VGC4040 sold individually or in a box?
Sold each, so you order the exact count the job needs rather than a carton quantity. Useful for MRO stock where you are keeping a few on the shelf for splice repairs rather than buying for a full run.
