What size circuit breaker for residential water heater?
40 gallon electric water heater. Dual 4500 watts. What's the correct size wire and circuit breaker?

#10-2/g cable and 30A double pole breaker. Some jurisdictions require a disconnect at the unit (air conditioner pull-out style is OK). Some jurisdictions require that the connection from the wall/ceiling to the unit be protected -- flex conduit or metal cable for example.
