I am looking to install a whole-house surge suppressor as part of my electrical upgrade.
I'll be going from a 100a to 200a service, moving the meter location, changing from an overhead drop to a buried line, and installing a meter/main at the new drop point.
I have a new 200a panel that will be installed as a sub-panel from the meter/main, and my existing main (only) panel will have the neutrals & grounds split so it can be a sub-panel off the meter/main, as well.
I have zero space available in the existing panel, but plenty of space in the new (40 space) panel. I don't yet know what the electrician will be supplying as the meter/main and how many spaces will be available in it.
Can I install a whole-house surge suppressor in the new sub-panel and expect it to work properly, or does it have to be installed in the meter/main panel?
