I. required to have a weatherproof cover installed
II. permitted to be connected to circuit on the load side of the air conditione disconnection means.
III. Both I and II

Answer 1

The outdoor receptacle for the air conditioner is required to have a weatherproof cover and is permitted to be connected to a circuit on the load side of the disconnection means, ensuring safety and functionality.

Step-by-step explanation:

The National Electrical Code (NEC) specifies standards for electrical wiring and equipment to ensure safety and prevent hazards. When installing a service receptacle for an air conditioner on the roof of a shopping center, the receptacle is:

1. Required to have a weatherproof cover installed.
2. Permitted to be connected to a circuit on the load side of the air conditioner disconnection means.

Both of these requirements are important to ensure the safety and functionality of the outdoor receptacle. The weatherproof cover protects the receptacle from environmental conditions that could damage it or pose a danger during servicing. Additionally, having a connection on the load side of the disconnection means allows for easy power access during maintenance without affecting the main power supply to the equipment.
