The Inside (commercial/industrial) Wireman’s job is to distribute and connect the customer’s electrical equipment to that power source. The Inside Wireman installs and maintains all the various types of electrical systems found in commercial and industrial facilities. Equipment used may include lighting, receptacles, motors, heating equipment, and systems that control the operation of all a facility’s energy usage.

The Inside Wireman installs conduit systems that contain the wire from the motor control centers or panelboards to all of the equipment that uses electricity. Those conduits may contain power cables or control cables. Many of the conduit systems are exposed and must be installed to exacting standards using neat and workmanlike craftsmanship.

The work of an Inside Wireman can vary. One day the Inside Wireman could be installing a Fire Alarm System or Security System in a high rise building and the next day he or she could be installing conduit in a ditch on the outside of the building. Inside Wiremen also install electrical systems in industrial facilities such as chemical plants, power plants, chip manufacturing facilities and automobile plants. Each type of installation has specific electrical needs and systems to support those needs.
