Can circuits of 40A be used for fixed lighting with heavy-duty lamp holders in cooking appliances?

Using circuits of 40A for fixed lighting with heavy-duty lamp holders in cooking appliances is permissible because these circuits can handle the necessary load associated with high-wattage lighting typically used in culinary environments. In residential and commercial kitchens, lighting must often be robust enough to illuminate workspaces effectively, and heavy-duty lamp holders are designed to support the higher amperages without risk of overheating or failure.

A 40A circuit provides sufficient amperage to accommodate multiple fixtures, which is advantageous in settings where high-intensity lighting is required, such as when preparing food or in food service establishments. It's essential that both the circuit and the lamp holders are appropriately rated for the loads they will bear to ensure safety and compliance with electrical codes.

When using such circuits, proper installation and adherence to local codes and regulations governing electrical work, especially in a cooking environment, are standards that must be met. Having these considerations in place ensures a safe and effective lighting solution in cooking applications where heavy-duty fixtures are frequently employed.
