Question:
Good Afternoon,
Does the Code specify a minimum size branch circuit conductors for hot water heaters?
Thanks for your response.

Answer:
Hello Lane,
Thanks for the question. Section 422.13 indicates that branch circuit overcurrent device and the conductors for fixed storage-type water heaters that have a capacity of 120 gallons or less shall be sized not smaller than 125% or the rating of the water heater.
