13.7.2-8 Distinctive Connections

Each type of test or service equipment should have distinctively different connectors or fittings to minimize the likelihood of error.

Additional Information:
Providing visually distinct connectors or fittings for different types of test and service equipment may reduce the likelihood that a maintainer will mistake one type for another. Physical differences between different types of connectors and fittings may prevent a maintainer from connecting the wrong piece of test or service equipment, if it is physically incompatible with the test or service connector or fitting.
