Determining the Electrical Circuit for a Water Heater
Electrical Question #1: Can I run a water heater with two elements (one takes 30 amps and the other takes 20 amps) with wiring that is two 15 amp breakers?

This electrical wiring question came from Jack, a Homeowner from Tipp City, Ohio.

Electrical Question #2:

My ranch home, built in 2009, has an unfinished basement and the water heater is in the basement. There is one plug on the ceiling that the water heater is plugged into. When I trip the breaker for two of the bedrooms upstairs, that plug turns off as well. Is it required by code to have the water heater plug on a stand alone circuit? If not, can I run a few more plugs off that one as I wire my basement?

This electrical wiring question came from Dale, a Homeowner in Ankeny, Iowa.
