Ensure that you connect the surge panel to the 
breaker box wit PVC or similar non metallic conduit.
Metallic conduit will act as a choke preventing 
the surge from getting into the surge suppressor.
Most surges will be lightning induced and lightning is a high frequency event.
All grounds should be as short as possible, 
number 6 or larger inside the building.
Do NOT use braid for a lightning ground as the 
high frequency event does not like the bends back 
ad forth that make up the braid.

In a previous life, I inspected tower sites for lighting mitigation.

When properly installed, a whole house surge suppressor is very effective.
