I’m going to purchase a post-war ZW in the near future. I’m aware of the protection that should be added to it. Tvs, fuses/breakers, updated newer style circuit breaker in the unit etc.
My question is - is it worth it to wait and look for a ZW (R) model versus a regular ZW model. I know one of the main differences is the riveted core. Just wondering if it really matters all that much.
