recommended ground busbar?

To use this as a sub-panel, do I need to add a ground busbar? If so, what are part numbers (& URLs) of recommended busbar kits? In the product overview (for # QO142M200PC), it is mentioned that there are "3 ground bar mounting locations (left, right and end) to let user pick the easiest spot to wire". What are recommended part numbers, for each position?
Asked by: reModdler
You are correct that when installing as a subpanel that a ground bar kit is required. The label inside the panel door will provide the catalog numbers of acceptable ground bars or you can ask the electrical department associate in your local store.

Hey man, does this thing come with the ground bar?

Hey man, does this thing come with the ground bar?
Asked by: Dracula
Hey man, the typical installation is as a main service panel and a ground bar is not needed, the ground terminations should be on the neutral bus. The only time you need to install a ground bar kit is when this panel is installed as a subpanel.

QO 200 Amp Main Breaker 42-Space 42-Circuit Indoor Plug-On Neutral Load Center with Cover is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Square D Load Center When you are looking for the best you buy Square D. You pay a little more and about double for the circuit breakers. You get a much better product and I am willing to pay for that on such a critical item in my home.
