Rule 603. Meters with associated instrument transformers must be inspected to determine the proper operation and wiring connections. Inspections must be made within 60 days after installation by a qualified person who, when possible, should be someone other than the original installer. Socket-type meter exchanges are excluded from post-installation inspections, except that the original installation must be inspected when the meter is installed.
