A maximum of five 15- or 20-ampere circuits to supply lights, receptacle outlets
, and fixed appliances
shall be permitted. Such park trailers shall be permitted to be equipped with panelboards
rated at 120 volt maximum or 120/240 volt maximum and listed for a 30-ampere-rated main power supply assembly. Not more than two 120-volt thermostatically controlled appliances
shall be installed in such systems unless appliance
isolation switching, energy management systems
, or similar methods are used.
Exception No. 1: Additional 15- or 20-ampere circuits shall be permitted where a listed energy management system rated at 30 amperes maximum is employed within the system.
Exception No. 2: Six 15- or 20-ampere circuits shall be permitted without employing an energy management system, provided that the added sixth circuit serves only the power converter, and the combined load of all six circuits does not exceed the allowable load that was designed for use by the original five circuits.
Informational Note: See 210.23(A) for permissible loads. See 552.45(C) for main disconnect and overcurrent protection requirements.
