Blackburn WGB6B – Frequently Asked Questions
1) What wire sizes will the Blackburn WGB6B grounding bus accept?
The WGB6B copper grounding bus takes conductors from 14 AWG up to 4 AWG in each of its lugs, so a panel mixing #12 branch-circuit grounds with a heavier #6 or #4 grounding electrode conductor can all land on the same bar.
2) How many grounds can I land on a WGB6B bus bar?
Six. The WGB6B is a 6-position bar, meaning six separate conductors, each 14 to 4 AWG, get their own terminal. One conductor per hole is the rule for equipment grounds, so if you have more than six grounds coming into the enclosure you need a higher-position bar or a second bus.
3) Is the Blackburn WGB6B ground bar UL listed?
Yes, the WGB6B carries UL file E9809, which is the listing an inspector looks for when a grounding bus is added to a panel or enclosure.
4) Is the WGB6B bar copper or aluminum?
Copper. The WGB6B is a CU (copper) bus, so it is suited to copper grounding conductors without the dissimilar-metal concern you get pairing copper wire to an aluminum bar.
5) Does the WGB6B come with mounting hardware?
The WGB6B is supplied as a connector mounting hardware item, sold one bar per unit. It is the bus itself with its terminal screws; if your enclosure has no dedicated ground-bar boss, plan on the appropriate insulating base or standoff kit for the box you are working in.
6) Can I use the WGB6B as a neutral bar as well as a ground bar?
No. The WGB6B is a grounding bus, intended for equipment grounding conductors. Neutrals must stay isolated from ground downstream of the service disconnect, so a subpanel needs a separate insulated neutral bar, not this bar.
7) Do I order the WGB6B individually or by the box?
Individually. Blackburn's WGB6B ships as a single bar, each, so quantity one gets you one 6-position copper bus. Buyers standardizing across a building typically order one per enclosure being retrofitted.
8) Is the Blackburn WGB6B made in the USA?
Yes, country of origin on the WGB6B copper grounding bus is the United States, which matters on federal, municipal, and other domestic-preference jobs where documentation is required at closeout.
