Individual branch circuits are not required for portable X-ray equipment requiring no more than _____.

The correct answer is based on the National Electrical Code (NEC) requirements regarding branch circuits for specific equipment. For portable X-ray equipment, individual branch circuits are deemed unnecessary as long as the equipment does not draw more than 60 amps. This provision is designed to accommodate the operational needs of such equipment while ensuring safety and compliance with electrical standards.

In practice, this means that if the X-ray equipment has an electrical demand that remains at or below this threshold, it can typically share a branch circuit with other loads, reducing the need for dedicated circuits, which can be more costly and complex to install. This flexibility can be particularly beneficial in medical settings where space and electrical capacity may be limited.

The other choices, while they represent larger current ratings, exceed the threshold that defines when a dedicated branch circuit is required, as established by NEC guidelines. Thus, selecting a value higher than 60 amps implies a requirement for a dedicated circuit, which is not applicable in this context.
