One thing about the 3-way switches. I've found that the terminal designations move and the screws aren't always color coded. I've had to ohm out a few to connect them properly. No, I haven't the foggiest reason for electrical component manufacturers to do this. Your drawings are correct, one will just have to make sure which terminal is which.
Thanks

most times the screws are your key to which one is common. any one off color or black, brown is the common. eagle makes its common a deep brown color. leviton uses all brass screws with one a different shade of brass. older ones use all the same color (porcelain base) old mother of pearl push button porcelain are the same coloring. ringing out with a test light is a sure fire way of identifying the common.

Water Heater
Simple water heaters have two wires to connect to the feed. In your case the red and white go to the 220 cable coming from your breaker panel. Some have four wires - two pairs together to each of one cable to the panel.
They are connected internally to first the top controller and the lower controller to provide sequencial operation of the heating elements. the elements are each about 3000 watt. They can't operate together because of the high current draw, hence the sequencial operation.
Hot water stratifies to the top of the heater where its drawn off. The cold water "dip" tube goes to the bottom of the heater so the bottom element is the workhorse of the heater. Once its setting is satiafied, it opens and transfers to the top element controller which then operates.

Water Heater?
Does anyone have an electrical drawing of an electric water heater? It has two wires, R&W going to both heating elements. It is a basic Rheem system, 240v single phase and 50 gal capacity. I am not sure if you needed all of that, but it was on the face plate. Thanks everyone!
