Siemens MC4040B1200SECW Meter-Load Center Combination with 40 Space, 40 Circuit, 200-Amp and Surface Mount

The amount of room inside the panel. The organization of the wiring.

This is the best main panel for 200 amp users.It is wide lots of room for wire. 40 full space is good for any large house. It has large neutral/ground bar.

Package arrived and it looked as if it had been around the world. @ Siemens the default packaging might work fine for home depot shelf, but NOT for secondary delivery by USPS who throws it around!The description is wrong, it is for both overhead and underground service. There is a TON of room inside for both service entry and branch circuitry wiring. The largest residential panel I've ever worked on, easy!!!When received the 200A main breaker was NOT properly seated in the panel hooks. I had to unsrew the feeder conductors and remove the main and reseat it. The main has a screw near the load side which holds it securely in place, but not on the line side. I was able to fit a screw here to properly secure it, now I feel like it is better. @Siemens the line conductors are a tad too long and force the breaker out of the clips. Shorten the line conductors by about 1/4" and you are good to go.I wish the dead front hold ins at the top were on both sides or bigger otherwise it feels kind of loose.Over all more pros than cons. Siemens could correct these slight defects easily and make a better product for sure!

This listing is all screwed up. The panel is not the one shown in the image.The bus bar is ALUMINUM - not Copper at all.The main breaker comes installed at the bottom rather than as shown.

LOVE these combination meter/load centers!!! All my customers love them too. They look so clean and neat when installed.

Thanks
