TN-S system should be adopted as the grounding type of carousel's low-voltage distribution system; the metal shell of electrical equipment and non electrified metal structure must be reliably grounded; the protective repeated grounding resistance of low-voltage distribution system should not be greater than 10 Ω. In addition, the design and construction of the grounding device shall comply with the provisions of "code for design of grounding of industrial and civil power installations"; the insulation resistance between the live circuit and the ground shall not be less than 1m Ω.

The design function of carousel electrical system must meet the requirements of operation control and safety protection of the amusement facility, and meet the requirements of normal use under local environmental conditions. The amusement facilities with a height of more than 15m shall be equipped with lightning protection device. The lightning protection device must be connected reliably and its grounding resistance shall not be greater than 10 Ω. Carousel should not be set in the channel of high voltage overhead transmission and distribution line. If it is set, it must be approved by the local power management department.
