When installing a 120/230 volt coffee maker, how many prongs must the cap receptacle have to meet code?

When installing a 120/230 volt coffee maker, the appropriate cap receptacle must have a configuration that includes two hot wires, one neutral, and one ground. This setup is essential for ensuring the safe and reliable operation of the appliance.

In this case, the two hot wires are necessary because the coffee maker can operate on either 120V or 230V, depending on the intended use or local electrical code requirements. Having both options allows for flexibility in installation and ensures compatibility with varying electrical systems. The inclusion of one neutral wire is crucial to provide a return path for the current, especially when the appliance operates at 120V. The ground wire is vital for safety, preventing electrical shock and providing a path for fault current.

This configuration not only adheres to electrical codes, which are designed to ensure safety and functionality, but it also aligns with common practices for wiring in commercial food service equipment where appliances can demand significant power and operational versatility.
