Blackburn VGC44 – Frequently Asked Questions
1) What wire sizes does the Blackburn VGC44 parallel groove connector take?
The VGC44 is the 8-4 range Vicelock parallel groove connector, so it handles conductors from 8 AWG through 4 AWG. Both grooves work within that same range, which is what lets you tap or splice a 4 to an 8 without a separate reducer.
2) Do I need a crimp tool or hydraulic press for the Blackburn VGC44?
No press, no dies, no battery tool. The VGC44 is a mechanical parallel groove connector, so it tightens down with a wrench or socket on the bolt. That's the main reason crews pick this style for service work and repairs where dragging a hydraulic crimper to the location isn't practical. A compression connector is the alternative when the spec calls for an irreversible crimp.
3) Will the VGC44 work on aluminum conductors?
It's a bronze body, which is the standard material for copper-to-copper grounding and bonding connections. Bronze connectors are not the part to use on aluminum conductors, where you want a connector specifically rated for aluminum or dual-rated AL/CU, typically tin-plated and supplied for use with an inhibitor compound. Match the connector to the metal you're landing.
4) Is the Blackburn VGC44 connector suitable for direct burial or outdoor grounding runs?
It's a bare bronze mechanical connector with no insulation, which is the usual construction for grounding and bonding work where the connection is exposed, in a ground well, or buried. Bronze resists corrosion in contact with copper conductors. There's no jacket or cover, so if the application needs insulation you'll be taping or booting it yourself.
5) How much space does the VGC44 need inside a box or enclosure?
Plan around a 9/16 inch outside diameter for the body. That's the figure to check against tight raceway entries, crowded ground bars, or a pull box where several taps land close together.
6) What's the difference between a parallel groove connector and a split bolt for a 4 AWG tap?
Both are mechanical and both land two conductors side by side. A parallel groove body like the VGC44 seats each conductor in its own machined groove, which keeps the two runs positioned and is common on grounding electrode conductors and bonding jumpers. A split bolt wraps the pair inside the bolt itself. For an 8 to 4 AWG copper connection either style is in range, so the choice usually comes down to what the drawing specifies and the space you have, with the VGC44 body measuring 9/16 inch across.
7) Am I buying one connector or a box when I order the Blackburn VGC44?
The VGC44 sells each, one connector per unit. If you're standardizing a facility or kitting out a crew, order the piece count you need rather than assuming a carton quantity.
8) Which Blackburn part number do I quote for an 8 to 4 AWG Vicelock parallel groove connector?
Blackburn VGC44, bronze. That's the manufacturer part number to put on the purchase order for the 8-4 AWG Vicelock parallel groove body.
