Blackburn VGC23 VISE LOCK CONNECTOR 2/0SOL 3/0STR

The VGC23 is rated for 2/0 solid and 3/0 stranded conductor. That is the size range the connector is built around, so pairing it with smaller or larger conductor than that means picking a different model in the vise lock range.

Bronze body. Bronze is the standard choice for copper grounding and bonding conductors, since it avoids the dissimilar-metal issue you get putting aluminum-bodied connectors on copper.

No insulation on it at all, it's a bare mechanical connector. If the splice needs to be covered, insulation is a separate item you add yourself. For grounding electrode and bonding work that's normal, the connection is usually left bare.

Outside diameter is 9/16 inch, so it's a compact body and clears most small enclosures and pull boxes once the conductors are dressed. Measure the space you have after bending, since the conductor bend radius usually governs rather than the connector itself.

No. It's a mechanical connector, tightened with a wrench or hex driver rather than compressed with a crimp tool and die. That's the main reason contractors pick this style for field grounding taps, no press to haul out to the site.

Both are bronze mechanical taps for grounding and bonding. A parallel groove connector such as the VGC23 seats the two conductors side by side in grooves under a clamping body, which handles a solid conductor and a stranded conductor of different sizes, in this case 2/0 solid to 3/0 stranded, without deforming either one. A split bolt is the older, cheaper answer when both runs are the same construction and size. If you're tapping dissimilar conductor, the groove style is the one to order.

Sold each. Order the exact count you need for the job rather than working in pack multiples.

Manufactured in India. That's the figure to carry on a submittal or domestic-preference review for the VGC23.
