Task D-22 Installs and maintains motor starters and control devices
Task Descriptor
All electrical motors need a method to be started, stopped, protected and controlled. These controls can be as simple as a single switch, or as complex as a starter assembly. Industrial electricians install and maintain these starters and controls in the motor circuits. Mechanical starters are being phased out and replaced with solid state starters. This supports energy efficiency and reduces noise pollution.
For the purpose of this standard, “install” includes both new installations and upgrading of existing systems by removing and replacing motor starters, control devices and their components.
For the purpose of this standard “maintain” includes inspection, preventive/predictive maintenance, troubleshooting, replacing and repairing activities.

Task D-23 Installs and maintains drives
Task Descriptor
Electrical motors can be controlled by both AC and DC drives to achieve precision operation (e.g. speed, positioning) of the motors depending on the application. Industrial electricians install and maintain these drives in the motor circuits. They also perform maintenance to ensure motor drives and their controls are in good operating condition. For new installations, DC drives are becoming less common as a result of maintenance issues. AC can be rectified easily at a lower cost with less maintenance requirements.
For the purpose of this standard, “install” includes both new installations and upgrading of existing systems by removing and replacing components.
For the purpose of this standard, “maintain” includes inspection, preventive/predictive maintenance, troubleshooting, replacing and repairing activities.
Both installation and maintenance include programming and tuning.
