• Electricity meters, primary overcurrent protection equipment
• Outside and service entrance, service drop from pole to
building, run between meter and panel
• Overhead line to detached building, underground line to well
pump
CAT III Three-phase
distribution, including
single-phase
commercial lighting
• Equipment in fixed installations, such as switchgear and
polyphase motors
• Bus and feeder in industrial plants
• Feeders and short branch circuits, distribution panel devices
• Lighting systems in larger buildings
• Appliance outlets with short connections to service entrance
CAT II Single-phase
receptacle connected
loads
• Appliance, portable tools, and other household and similar
