PowerMark Gold 12-Hole Grounding Bar Kit

A:  The center-to-center distance between the mounting holes for the TGK24CP 24-hole grounding bar (where only 22 of the holes are usable for wires) is 9-3/4". The overall length of the bar is 10-7/16". The bar cross section is 1/2" x 1/2".

A:  Use the TLK20CP ground lug kit. It will >>JUST<< fit a 2/0 cable if the strands are perfectly arranged. Note that the more common TGL20CP ground lug kit does NOT fit this bar. Using the TLK20CP lug, will cost you 2 or 3 wire positions on the bar.

A:  Sorry, I mean, what grounding lug do I buy to attach to this bar that will accept a 2/0 aluminum wire. This will be used in a GE 40/80 panel that will be a sub panel. I need to connect the separate 2/0 aluminum ground wire that is required. Neutral and ground will be isolated from each other in this panel.

A:  This bar is attached inside the main fuse panel. It is designed for use with 14 and 12 gauge wire. The holes may also be large enough to use 10 gauge wire but I have not done so yet to confirm.

A:  Thank you for your question. The center to center mounting hole measurement for the TGK4CP is 3 inches.

A:  The center-to-center distance between the mounting holes for the TGK24CP 24-hole grounding bar (where only 22 of the holes are usable for wires) is 9-3/4". The overall length of the bar is 10-7/16". The bar cross section is 1/2" x 1/2".

A:  The center-to-center distance between the mounting holes for the TGK32CP 32-hole grounding bar (where only 30 of the holes are usable for wires) is 13-1/2". The overall length of the bar is 14-3/16". The bar cross section is 1/2" x 1/2".

A:  You are correct, for any GE/ABB ground bar longer than the TGK12CP (12 position) bar, they stiff you by 2 holes, lumping the mounting holes in with the wiring holes. Deceptive advertising in my opinion.

A:  Yes, there are 24 holes as advertised which leaves you 22 positions left for terminations after mounting the bar. Hope this helps.

A:  Interesting, I had not really counted them but if they said 24 holes and there are 24 holes....... I have not needed all of the holes so it has not been an issue. And yes, there should be 2 mounting holes to attach it to the panel or sub panel box as needed. But as a grounding bar it works great in my box.
