A lightning strike can damage wiring in a building. Specifically it can damage the insulation on the conductors, resulting in arcing and fire, either immediately or some time after the strike. I've seen insulation testing conducted after such a strike. This involves opening each breaker, disconnecting every load, and putting a voltage on the circuit to see if the insulation breaks down. For a structure of any size, this can be very time-consuming.
I can imagine an alternative: simply replace all breakers in the building with arc-fault interrupt breakers. If any arcing is happening, or starts after the fact, the breakers will trip and prevent a fire, and give a strong indicator of what circuit the damage is on. It almost certainly costs less than insulation testing every conductor, and while it's not the same kind of testing, it's a very effective test every second for the rest of the life of the structure. Plus it helps bring the building up to code, especially if you install breakers with GFCI capability as well.
Is there a reason this would be a bad idea, from a technical or safety standpoint?
