Does this protect the whole panel or just one side? Would a sub panel require it's own?

Hello, Yes, it will protect the whole panel. Though one SPD can protect the main panel and its sub-panel, we still recommend having SPD in each one. You can contact us anytime using our chat live https://www.se.com/us/en/work/support/customer-care/contact-schneider-electric.jsp where an agent will be able to give you further assistance on this matter. Warm regards. Schneider Electric Customer Care
