Hi. I've got a surge protector installed at the main electrical panel. Any advantage to also installing dedicated surge protectors right at the mod-con and ODUs? Thanks

    Probably. Main panel surge protectors usually don't clamp smaller surges, but the newer whizzy things are still sensitive to them.
