I am a little stumped on this one. I am replacing my old electrical hot water heater soon. a 240v breaker in there, pretty sure 30amp, though I haven't checked.
I know my old hot water heater uses a single 4,500w cathode so it is possible it is a 20amp 240v breaker (if such an animal exists).
I am looking at getting a Whirlpool EE3J50RD045V which states that it has two 4,500w cathodes, however in the user's manual it says the electrical hookup is a single 240v 30amp breaker, which only comes out to a max of 7,200w, well below what two 4,500w cathodes would draw. So I am a little confused by this. Is the user's manual wrong and it requires a single 240v 50amp breaker? Or does it use a pair of 4,500w 240v cathodes, but doesn't power either cathode at the full 4,500w?
I am trying to figure out if I need to upgrade my circuit or not, also a little confused by the 4,500 dual cathodes. Thanks.
