High power load appliances should not be plugged into which of the following?

High power load appliances should not be plugged into power strips because these devices are typically not designed to handle the high current demands of such appliances. Power strips are meant to distribute power to multiple low to moderate load devices, like chargers or small electronics. When a high power appliance is connected to a power strip, it can exceed the strip's capacity, leading to overheating, electrical fires, or tripping circuit breakers due to the excessive load.

In contrast, wall outlets, heavy-duty extensions, and surge protectors (if rated appropriately) can generally handle higher loads, making them more suitable for high power appliances. Heavy-duty extensions and surge protectors specifically designed for high power appliances have features that allow them to safely manage the energy demands without risking damage or hazards.
