Electrical load refers to the amount of electrical power consumed by devices or systems in a given period. It is measured in watts (W) or kilowatts (kW) and can include anything from household appliances like refrigerators and air conditioners to industrial machinery. Understanding electrical load is essential for designing electrical systems that can safely and efficiently supply power. The total electrical load on a system can vary based on usage patterns and the number of devices connected. Engineers often calculate the load to ensure that electrical circuits, such as those in homes or commercial buildings, can handle the demand without overheating or causing outages. Proper load management helps maintain safety and efficiency in electrical systems.
