Individual elements or units of either water tank heaters or space heaters shall not exceed 30 amperes capacity, nor shall the total load controlled by a single thermostat exceed this amount. If a central electric heating plant is used, the heating elements shall be so controlled that not to exceed 30 amperes is connected or disconnected at one time.
The regulation limiting the demand to 30 amperes may be waived if, in the judgment of your District, such a load would not be detrimental to its system.
