For an optional standby system using EV and its EVSE, which requirements must be followed?

The correct choice is significant in the context of optional standby systems, particularly the use of Electric Vehicles (EVs) and Electric Vehicle Supply Equipment (EVSE). The standards that pertain to these systems establish guidelines for their safe and efficient operation.

When considering requirements for optional standby systems that utilize EVs, the appropriate reference to apply is found within the context of 702. This section outlines the provisions for optional standby systems, which are defined as systems that provide power to selected loads during an interruption of the primary power source. It includes specifications related to installation, maintenance, and operational safety, ensuring that the systems are not only effective in providing power but also compliant with safety norms.

In this context, the distinctions of 701, 703, and 704 relate to other categories of electrical systems. For instance, 701 deals with systems classified for essential facilities, which could potentially have different operational requirements due to their critical nature. Similarly, 703 concerns systems designed for permanent installations connected to the utility grid, which may not pertain explicitly to optional standby applications. Lastly, 704 is oriented toward the topic of emergency systems, which also does not match the optional standby parameters.

Thus, understanding the relevance of these standards is key for ensuring that EV
