Square D - QO160M200PC 200-Amp 60-Space 60-Circuit Indoor Main Breaker Plug-On Neutral Load Center with Cover

One of the best main panels on the market. Solid build quality. Made of heavy gauge steel compared with other brands. Copper bus. Supports plug-on neutral breakers (makes panel installation very easy). Best price among online retailers.The only drawback is that it doesn't come with a real door/cover. You have to buy it separately.10-26-2018 Update: I called Schneider Electric to discuss quality issues with the cover door for this main panel that is sold separately (search for QOCDK60 and see my Amazon review for that product). I was told that Amazon is not an authorized reseller for Schneider Electric and, therefore, any Schneider Electric/Square D product I buy on Amazon is not covered by warranty (this main panel is supposed to come with lifetime warranty.) I'm taking off two stars for this poor warranty coverage. It doesn't detract from the quality of this product. But buyers beware of the warranty trap.

We are a licensed electrical contractor and do dozens of panel changes every year, so we know what we are doing.This panel appeared fine, package was undamaged, but we discovered the main breaker on it was faulty, so we had to go to buy a new one locally to get our customers power back up. Was told by square d that it was not purchased from an authorized retailer, so we don't have warranty support from their end. I guess that's the risk you take ordering on amazon.
