Blackburn 54875 – Frequently Asked Questions
1) What wire sizes does the Blackburn 54875 grounding connector accept?
The 54875 is a Figure 6 compression connector rated for 6-2 AWG on the main run and 6-2 AWG on the tap, so the same size range on both conductors. That covers the typical 6 AWG grounding electrode conductor and larger taps up to 2 AWG. Sold each.
2) Is the Blackburn 54875 a mechanical lug or a crimp connector?
It's a compression (crimp) connector, not a set-screw mechanical lug. You install it with a hydraulic or battery compression tool and the correct die for a Figure 6 C-tap, and the joint is permanent once crimped. If you need a connection you can take apart later for testing, use a bolted or split-bolt mechanical connector instead.
3) Will one 54875 connector handle a ground rod tap where the main is 6 AWG and the tap is also 6 AWG?
Yes. Because the range is 6-2 AWG on both the main and the tap, the 54875 handles same-size combinations like 6 to 6 or 2 to 2, as well as mixed runs such as 2 AWG main with a 6 AWG tap. Anything smaller than 6 AWG or larger than 2 AWG needs a different figure size.
4) Can I use the Blackburn 54875 on aluminum conductors or direct burial?
The 54875 body is copper, so it is intended for copper conductors. Copper compression C-taps of this type are the standard choice for grounding electrode and bonding jumper splices, including the kind of buried and concrete-encased connections a grounding system uses, where a permanent irreversible joint is wanted. For aluminum or copper-to-aluminum transitions, specify a connector listed for AL9CU.
5) What does the Figure 6 designation on this Blackburn connector mean?
Figure 6 identifies the barrel size and shape of the C-tap, which in turn tells you which compression die and tool setting to use. Ordering by figure number matters more than the wire range alone: a crimp made with the wrong die on a Figure 6 body won't make a sound connection. The 54875 is the Figure 6 body sized for 6-2 AWG main and 6-2 AWG tap.
6) What part number do I order for a 6 AWG to 2 AWG ground tap, and is it made in the USA?
Order Blackburn 54875. It's the E-Z-Ground Figure 6 compression connector covering 6-2 AWG main to 6-2 AWG tap, sold as each, and country of origin is the United States. Useful if your job spec or a government or institutional contract carries a domestic sourcing requirement.
