Major Work Activity B – Installs, services and maintains generating, distribution and service systems

Task B‑7 Installs, services and maintains consumer/supply services and metering equipment.

Task Descriptor

Service entrance equipment provides power for single-phase and three-phase electrical systems and equipment. Consumer services can provide normal, emergency and temporary power. This equipment allows for the safe utilization of electricity.

For the purpose of this standard, installation includes both new installations and upgrading of systems by removing and replacing components.

Construction electricians service single- and three-phase consumer/supply services and metering equipment by troubleshooting, diagnosing faults, and repairing them. They also perform maintenance to ensure the consumer/supply services and metering equipment are in good operating condition.

Industry Expected Performance

The task must be performed according to the applicable jurisdictional codes and standards. All health and safety standards must be respected. Work should be done efficiently and at a high quality without material waste or harm to the environment. All requirements of the manufacturer, client specifications and the AHJ must be met.

At a journeyperson level of performance, all tasks must be done with minimal direction and supervision.

Task B‑8 Installs, services and maintains protection devices.

Task Descriptor

Overcurrent protection devices provide protection against overcurrent and short circuits to service entrance, feeder and branch circuit conductors, and equipment. Ground fault protection devices provide protection against shock and current leakage and are usually used in conjunction with overcurrent devices. Arc fault protection devices provide protection from the effects of arc faults by de-energizing the circuit when an arc fault is detected. These devices also have overload protection for the circuit. Surge protection devices prevent transient voltages that originate outside from entering into the whole system.

For the purpose of this standard, installation includes both new installations and upgrading of systems by removing and replacing components.

Construction electricians service overcurrent, ground fault, arc fault and surge protection devices by troubleshooting, diagnosing faults, replacing devices and repairing them. They also perform maintenance on these devices to ensure they are in good operating condition.

Task B‑13 Installs, services and maintains renewable energy systems.

Task Descriptor

Alternative and renewable energy generation systems can be used to supplement power when power from the utility is unavailable or the building is isolated from the power grid. These systems can also feed energy back to the power grid. For the purpose of this standard, alternative systems are considered non-utility systems. Renewable systems are systems such as solar, wind or tidal powered that use renewable sources of energy.

For the purpose of this standard, installation includes both new installations and upgrading of systems by removing and replacing components.

Construction electricians service alternative and renewable energy systems by troubleshooting, diagnosing faults, and repairing them. They also perform maintenance to ensure alternative and renewable energy systems are in good operating condition.

Industry Expected Performance
