What value should be used to calculate the EVSE load?

In electrical installations, particularly when dealing with Electric Vehicle Supply Equipment (EVSE), it is important to use the nameplate rating of the equipment for load calculations. The nameplate rating reflects the maximum expected load that the equipment will draw while in operation, ensuring that the electrical system is adequately sized to handle the demand without risking overloading.

Using 7200 watts or the nameplate rating ensures that the infrastructure can support the load safely, accommodating any potential surges or variances that could occur during operation. This approach aligns with safety standards and helps prevent potential hazards such as overheating or tripping breakers due to unexpected load conditions. Calculating the load based solely on average usage or arbitrary wattage values may not provide sufficient reliability or safety for the system, making the nameplate rating the preferred choice for EVSE load calculations.
