What is the maximum over-current protection for infrared lamps used in commercial and industrial heating appliances?

The maximum over-current protection for infrared lamps utilized in commercial and industrial heating appliances is set at 50 Amps. This is in accordance with the National Electrical Code (NEC) and applicable local codes, which outline specific requirements for the protection of heating elements. Infrared lamps are typically high-wattage devices that require adequate over-current protection to prevent overheating and potential hazards.

Selecting the appropriate over-current protection ensures that the wiring and components can handle the load safely without tripping under normal operating conditions. If the current exceeds 50 Amps, it may indicate a fault or overload, which the protection device should mitigate by tripping. This regulation is essential for safe installations, and maintaining compliance with it is crucial for the prevention of electrical fires and equipment damage.

Understanding this safety measure helps ensure that heating systems operate reliably while reducing risks associated with electrical failures.
