About Lesson

Step 1: Identify the type of service that you are working with, which could be overhead or underground.

Step 2: Find the correct column for the service voltage. The table lists three voltage ranges: 0-600V, 601-1000V, and over 1000V.

Step 3: Look for the correct row for the type of service you are working with. The table lists several different types of services, including single-phase, three-phase, and delta-delta. Each service type has its own row in the table.

Step 4: Identify the minimum size of service conductors for the specific service you are working with.
