Deciding on whether to install a Surge Protection Device directly onto the power lugs at the exit from the meter vs attaching a breaker with the surge protection built into the breaker, like the Siemens QSA2020SPD.
If the Surge Protector is connected directly to the lugs at the meter, the wire is very small as compared to the wires leaving the meter to feed the breaker panel. If attached this way, would the surge even get to my Surge Protector 'before' it hits the breaker panel? I'm wondering if the thick wire would transmit the electricity 10X faster since it is at least 10X the diameter of the small wire? If so, then putting the Surge Protector on the breaker panel would be more effective. On the attached Pic, you can see my old Surge Protector attached to the meter at the bottom - it is the single black wire leading down to the surge protector on each side of the meter output.
The breaker panel is located in a box right next to this meter box and so the length of the large gauge wire is probably 2ft to the panel that would house the Siemens QSA2020SPD.
So, which Surge Protector would receive the surge first - thus protecting the system better.
