Imagine 2 separate circuits through the power meter.How is throttling my amperage going to stop me from using my A/C unit?
1. Normal everyday path.
2. Restricted path limited to say 10 amps 110.
You could run the smaller window units sure and your tv probably. But that’s about it, anything close to or over the limit could trip the “breaker” and no power. Self resetting breaker kicks back on in a minute or two after it cools off.
