I am aware of that and had a healthy discussion with my electrician and his boss. I was told even though you can dial the amps down, the unit still requires an amps and wiring that would be too much for my box and would not pass the code inspection regardless of being able to manually turning the pro station down. This was the 4th electrician I invested time into and was told the same thing by each one. The only alternative I was given was to have a second meter installed which would have cost a fortune and was ultimately not worth it.
