Upon opening the box I was surprised how heavy gauge the metal is for an interior box, it's thick, and because it's thick, it's pretty heavy for an interior box, that being said, it's quite nice and solid, this particular model handles up to 40 breakers, if you look at the pictures you can see it has a solid continuous neutral bar which is nice,. Interior box so keep that in mind

This Square D QO 200 Amp, 40 space, 40 circuit indoor main breaker load center is another quality product made by one of the industry's best brands. This load center comes with the convenient Plug-On-Neutral feature which saves labor time, has fewer connections and frees up space making it easier to run wires and is safer. It also includes a combination surface or flush mount indoor cover and can take a optional door lock. I really like the new plug-on-neutral feature and it makes the installation of circuit breakers easier and much less cluttered. I plan to update my older load center in my home which is a rats nest of wires and upgrade all the breakers to plug on neutral. I will also use GFCI (ground fault) and or AFCI (arc fault) breakers for safety and to meet the latest National Electric code. Square D warrants its QO branch circuit breakers and load centers to be free from defects in material and workmanship for the lifetime of the load center in which it is installed.

We are about to up the amperage coming into our house. In preparation of the upgrade I am supplying the load center which my electrician will install for me. My electrician just came over and when he saw what I purchased he gave me a discount as with the plug on neutral breaker this saves him a lot of time and work. Absolutely incredible load center which is 200AMP, 40 space, 40 circuit indoor, which can expand up to 60 circuits. This incredibly well made load center comes with a shielded, tin-plated, copper bus bar that is plated for reliability. Another excellent feature is the quick plug-on neutral breaker connection on every circuit. Even includes main breaker, cover and shielded copper bus bar. Compatible with any QO circuit breaker (except CTL Tandems). 3 ground bar mounting locations (left, right and end) let you pick the easiest spot to wire.

This Square D 40 space indoor load center is an easy to install, simply constructed load panel for most houses. This panel comes with a 200 amp main breaker, and no ground bar. The 200 amp break comes factory installed, and will accept aluminum or copper mains. 40 spaces is a good start for most homes, but an all electric home may require more than 40 breaker spaces. This panel can be used as a subpanel if a ground bar is installed and its properly put in to code. The circuit breakers available range from 15 amp to 200 amp dual pole breakers. So there is no problem finding breakers you require for your project. I like this panel, good quality, easy access, and plenty of room for growth.

I purchased this panel to be used as a sub panel for my garage. First off - you cant go with the quality of Square D QO. The panels enclosure it strong and the metal box feels of good quality. The breakers bit the buss strong and there is little play once a breaker is attached. There is ample room for running wires along the side of the panel with 24 spaces you wont have issues with wiring cramming. Getting the cover on initially is a little tricky cause the holes for the screws arnt tapped. At first it might seem like you are cross threading the cover screws but once threaded they work fine. Just use your drill and apply a bit of pressure for the cover screws. The panel has plenty of 1/2'' knock outs on the top and bottom as well as the sides if you decide to surface mount it.

    Another quality product from SquareD, very easy to install, replaced a 35 year old SqD QO panel with a bad main breaker. The removable interior makes installing the can easy, and the generous space for the feeders make termination easy. The yellow feeder lug covers add a high degree of safety as well. And the price is far less than a very hard to find main for my old panel was. I added the plug in surge protector, also available through Home Depot. As a professional electrician Square D is the only brand I use in my home and jobs.

    The panel completely met my expectations, very pleased with it. However the cover directory that comes glued on was folded and creased making the last few rows unusable. I tried to contact Square D with no success. Would like to get a replacement. Order and delivery was great. Very pleased other wise.

      Well made. Easy to install. Came with 200 amp breaker-disconnect. I added four ground terminals to make ground terminations easier.
