I'm building out a smoothie shop. Three-phase panel. The prints show a water heater, but give no specs. I ask the owner how big a breaker I need for it. "20 amps" he says. "Seems small for your needs", I say. "I'll ask the plumber", he says. A while later he texts me. "40 amps". OK, I think that sounds reasonable. But, I remember the three-phase panel. "Hmm, is it a single phase or three phase water heater?", I wonder. Rather than order the wrong breaker, I drive down there to see. I bring a spool of #8 and some 3/4" EMT. I'm either running 2 hots or three. Either way it fits in the 3/4". Yup, 40 alright. 40 gallons. Single-phase 25 amp breaker.:slaphead: Good thing I also have a roll of 10/2 MC.
