A commercial electrician usually works in businesses like retail stores, restaurants, and offices, and their work usually involves the installation of power outlets and lighting. There are many more commercial electricians than industrial electricians since there is less training required for this position.
Some of the duties commercial electricians handle include:
Repairing internet and telephone lines
Electrical wiring work at new construction sites
Repairing parking lot lines
Electrical installation when remodeling a business
Electrical work at apartments
Commercial electricians use a three-wire system that allows each wire to carry less voltage. In residential locations, these electrical wires are usually hidden behind walls or in the rafters, but commercial electricians work with electrical components that are exposed. You can spot them along the ceilings and interior walls of businesses and office buildings. Sometimes, commercial electricians are required to work with high voltage systems, especially when they’re repairing large heaters or HVAC systems. Most often, they’re busy replacing outlets and ensuring that the lighting works.
