Restaurants depend on electricity to power cooking equipment, cash registers, refrigerators, freezers, security systems, lights, and the heating, ventilation, air conditioning (HVAC) system. Visit a local fast food restaurant and list all the electrical devices you notice. Using online resources, determine the restaurant’s power requirements for the devices in your list.
