What type of load is fixed outdoor electric deicing equipment considered?

1. intermittent

2. continuous

3. resistive

4. inductive

The correct answer is: continuous

Fixed outdoor electric deicing equipment is classified as a continuous load because it is designed to operate for an extended period without interruption. A continuous load is defined as one that runs for three hours or more at its rated load, which aligns with the purpose of deicing systems that are often activated throughout winter conditions to maintain a clear and safe environment. Understanding this classification is important for electrical design and safety regulations, as continuous loads require circuits to be sized with the appropriate ampacity to handle the heat generated over prolonged use. This ensures that the wiring and other components can manage the increased demand without overheating or failing. In contrast, intermittent loads operate only for a limited duration and do not require the same considerations for sustained operation. Resistive and inductive classifications refer to the nature of the load in terms of electrical characteristics (like heat generation versus magnetic fields), which is relevant but does not pertain to the operational duration attributed to fixed outdoor electric deicing equipment.
