Hi All, I have a question maybe you guys can easily answer. I have purchased a Hubbell Electric Booster Heater for a commercial dishwasher. I am getting ready to run the branch circuit to supply power to the Water Heater. I pulled the following screenshot from the Owners Manual. The model that I have is the 240VAC 1PH 12KW highlighted below. I noticed that in the table they call for #6 wiring, 3/4" conduit and a 65A breaker. I have always thought that a branch circuit with #6 wire could be protected by a maximum of 60A breaker. Are their specs correct as far as NEC is concerned or should I go with #4 wiring for the 65A breaker?
