The maximum amperage for fixed in place X-ray equipment that can be supplied through a suitable attachment plug cap is 30 Amps. This limitation is important primarily for safety reasons, as exceeding this amperage could lead to overheating of the plug, potential fire hazards, or damage to the electrical infrastructure.

In the context of electrical codes and standards, such as those from the National Electrical Code (NEC), specific guidelines are established to ensure that equipment does not exceed the safe current limits when utilizing plug connections. These standards are crucial in environments where precise electrical safety is necessary, such as in medical settings involving X-ray machines.

It's also important to note that equipment designed for higher amperages typically requires hard-wiring and specific disconnects rather than relying on standard attachment plug caps. This ensures secure connections that can handle the required loads without risk.

Understanding these standards helps electricians ensure compliance and prioritize safety when installing or maintaining electrical systems for such specialized equipment.
