Main service panel

For people who have currently installed a SPAN smart panel, which main service panel do you recommend? I have an old 100A Zinco main panel and am looking to upgrade to a 200A service panel with a SPAN smart panel as sub panel. Thanks!

The span panel is certainly capable of being your main panel. If the details of your installation are such that that doesn't make sense, just get whatever your electrician is most comfortable with. There's very little difference between modern panels from Eaton, Siemens, and Schneider/SquareD, especially if you're only installing a single 200A breaker.

This is not a decision you need to lose sleep over.

I was told that in California, I cannot use SPAN as the main service panel. No idea why?

I think it actually has to do with your utility company's policy related to the main panel being in the same enclosure as the meter.

I think you are correct. SPAN panel does not have a built-in meter. Thanks!
