According to the National Electrical Code (NEC), the branch circuit overcurrent protection and conductors for a storage-type electric water heater with a capacity of 120 gallons or less must be sized at not less than 125% of the rating of the water heater. This ensures that the wiring can handle the electrical load without overheating.
