For a 230 volt three phase fryer installation, how many prongs must the cap and receptacle have to comply with code?

• A. 2 hots and 1 neutral
• B. 3 hots and 1 ground
• C. 1 hot and 2 grounds
• D. 4 hots

Answer: (B)

In a 230 volt three-phase fryer installation, complying with the National Electrical Code (NEC) standards requires the proper configuration of prongs in the cap and receptacle to ensure safe and effective operation. The installation must include three hot conductors, each supplying different phases of the electrical supply, and one ground conductor, which is essential for safety. Using three hot wires allows the fryer to effectively distribute the electrical load across the phases, promoting balanced operation and reducing the risk of overloading a single phase. The inclusion of a ground conductor enhances safety by providing a path for fault current, which can reduce the risk of electric shock or fire. In contrast, configurations that do not include three hot wires would not meet the operational requirements of a three-phase system, and setups with insufficient grounding fail to comply with safety standards. Therefore, the correct configuration that meets both operational performance and safety regulations is three hot prongs and one ground.
