What the OP is describing is abnormally high in my view. Based purely on my own personal experience, the structured wiring in my parent's house I put in in the mid 90's has never suffered a failure, is still in use today, and it's in a residential environment with dogs and cats. I'd expect a properly managed environment to fare at least as good as that. ~Seth
