Residential wirers work with blueprints and code to install and maintain electrical circuits, wiring systems for residential buildings. They may work with home automation, security systems, fire alarms, fiber optics and computers.
Electrical work can be done indoors or outdoors. The work is sometimes physically strenuous requiring prolonged standing in cramped or uncomfortable positions. Electricians may work in dusty, dirty, hot and wet conditions, or in confined areas, ditches or other uncomfortable places. Electricians follow strict safety procedures to prevent injuries from electrical shock, falls, and cuts.
In the classroom, apprentices learn blueprint reading, electrical theory, electronics, mathematics, electrical code requirements, and safety and first aid practices.
