Default Surge protection for an ATS

Is the purchase of a surge protector placed between the utility in put and the ats cost effective. How would I know if the surge suppressor did any good and actually protected the ats? Please can someone please help me make the right selection or decision?

Thanks

There's really nothing that a surge protector on the utility power feed can do to protect an ATS.

I'm assuming a whole-house generator system in saying this: If you were going to install a large surge protector, it should be located between the ATS and the distribution (breaker) panel so that it works for both utility and generator power.

And to add to that, you would need surge protection between the utility and ATS and between the gen. and ATS for protection of the ATS. But for a little peace of mind a lot of power companies offer whole house suppressors that plug into the meter base. The bottom line is you are more at risk from a surge on the utility side than the generator side.

Do the three 5 amp fuses in a service rated transfer switch provide any surge protection (N1, N2, T1)?

No. They are only in place for the sensing and battery charger circuits to protect from over current... such as a short to ground from a skinned wire.
