Assume that a building manager instructed you to install a water heater. The specs on the water heater nameplate reveals the following 240V, 2PH, 60HZ, 5.7KW. The manager insisted for the installation to be done with 10 AWG copper THWN-2 conductor, the length of run is 1200 FT away from the service panel. Calculate the voltage after the installation.
Please confirm that my solution is correct, especially the block diagram. Please DRAW (not type) what the block diagram would look like if it's incorrect.
thank you
