(a) Lot service equipment shall have the capacity to supply the unit, appliance, accessory building or structure, and building component located on the lot. The park operator may prohibit the installation of a unit, appliance, accessory building or structure, or building component that exceeds the rated capacity of the lot electrical service, unless the load in the unit, appliance, accessory building or structure, or building component is reduced. If the unit or electrical appliance is allowed to be installed by the park and the connected load on the lot exceeds the rated capacity of the lot electrical service equipment, the lot electrical service equipment and feeders shall be replaced with equipment and conductors properly rated to supply the unit, appliance, or accessory building or structure. Notwithstanding the provisions of this subsection, park approval is required when an alteration or addition to the existing electrical system of the unit, appliance, accessory building or structure, or building component will exceed the rated capacity of the lot service equipment.

(b) The enforcement agency may order unsafe installations of existing electrical systems or portions thereof to be reconstructed or altered, if necessary for the protection of life and property.

(c) The use of electrical equipment and installations in existence prior to the effective date of applicable amendments to this chapter may be continued, provided such equipment and installations are maintained in safe operating condition and the calculated connected loads do not exceed the rated ampacity of such equipment and installations.

(d) Lot electrical service equipment may continue supplying accessory buildings or structures or building components or other electrical equipment located outside the unit, provided the lot electrical service has the capacity to serve them and the equipment is maintained in a safe operating condition.
