Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Top of the line quality and ease of installation. Square D QO is truly the best there is when it comes to panels. The construction layout of the panel is tops. 30 breaker spaces, ample neutral lugs, ease of installation are phenomenal. This panel comes with the 150 amp main breaker. It does not come with ground bars which I recommend buying separately and using even if you are bonding grounds and neutrals together in your panel as the first point if entrance/ service. Only use the green bonding screw if the neutral and ground are not bonded at your meter (they should be) or if your inspector requires it (he probably doesn't know much anyways but he's got the authority). The panel has many concentric and eccentric knockouts which make bringing Romex or pipe into the panel easy...just be careful not to knock them out bigger than you need. I have never installed a better electrical panel than square D QO! February 12, 2013
Rated 5.0 out of 5.0 by Great product I paid a little bit extra for commercial grade product and I am really happy I did that. You can definitely see the difference. Attached picture shows old and new panel. June 18, 2013
