wheres the right location to install a surge protector on a electrical service?

Closest to the end the surge will be comming from.

Use a multi-step approach.

Residential apps, one at the service disconnect, and one at the end unit, ie computer recep ect.

Commercial apps, at main service disconnect, and at every sevice disconnect after every SDS, and at end unit.

I go with TVSS/surge combos.

Dnk is right.
Also be sure all of your other providers (phone, cable etc) are securely bonded to the electrical grounding electrode system.
