Clarification

Resolution:
If the Load centers have individual feeds then you will need two HEPD80 SPD units.  If the Load centers are mounted side by side, with one incoming feed, and the 1st Load center has a breaker feeding the other Load center , one SPD in the first load Center is only needed and will provide protection for both of the Load centers .
