Why do you think the wire rating should be any different than in the house?|
Wire size should be rated for the full amount of the breaker. A 15 amp breaker will not trip at 15 amps immediately. It takes several minutes. Some it takes almost twice that to ever trip them.
An electric water heater is a pretty constant load.

Barn wiring is pretty simple. Your wire needs to be rated at a bit above half the breaker amperage to handle the anticipated constant amperage. Max current only happens when lights are first turned on and motors/fans start. It's not like a house where you would be running several appliances at one time.
