The Power Link Square D Breaker was the begining of what was called then, smart house. It was really pretty basic, yet revolutionary at the time, for use in custom high end homes.

During my 5 year assigment in Houston, at year #12 with Square D, there was a resi contr who did every type of resi there was, to include custom spec homes, and I had the contract. I also did same with a subsidiary of Exxon building homes.

Makes me wonder if any Nunchi tech is in these advanced products now?

I'll let Tony et al figure it out...capiche?
