Did you know that, according to the Bureau of Labor Statistics, more than 700,000 jobs were available for electricians in 2021? Electricians play a vital role in residential and commercial settings, helping with everything from fixing in-home lighting to wiring large-scale buildings.

But what exactly does an electrician do? And how can you start a career in this field? Keep reading to find out.

What Is an Electrician?

Electricians are skilled tradespeople who design, install, maintain, and repair electrical wiring systems. They work in various settings, including homes, commercial buildings, and industrial sites. Electricians handle electrical systems of all sizes, from small outlets to large machinery.

The scope of their work often depends on their expertise and specialization. Some electricians focus on intricate details like residential wiring, while others work on larger equipment or commercial systems.

Types of Electricians: Residential vs. Commercial

Electricians generally fall into two primary categories:

1. Residential Electricians

2. Commercial Electricians

Both categories involve specialized training and skills, but their responsibilities differ significantly.

Residential Electricians

Residential electricians focus on electrical systems in homes. Their responsibilities might include:

• Installing and maintaining lighting fixtures

• Repairing electrical panels and surge protectors

• Diagnosing and resolving wiring issues

• Following technical blueprints to ensure compliance with safety codes

Becoming a residential electrician requires training, documented work experience, and licensing, which vary depending on state requirements.

Commercial Electricians

Commercial electricians handle electrical systems in large public or private buildings, such as malls, offices, and factories. Their duties may include:

• Wiring large-scale electrical systems

• Installing control panels and machinery

• Conducting regular system maintenance and repairs

Commercial electricians often work with three-phase electrical systems, which require advanced training and knowledge compared to residential systems.

Key Differences Between Residential and Commercial Electricians

Though both types of electricians share some basic skills, here are five major differences to keep in mind:

1. Scope of Services

Residential electricians focus on smaller-scale projects like homes and apartments, while commercial electricians handle larger, more complex systems.

2. Equipment and Supplies

• Residential systems typically use single-phase wiring (120-240 volts).

• Commercial systems often use three-phase wiring (up to 480 volts) with heavier-duty cables and insulation.

3. Technical Training

Commercial electricians require additional training in phase balancing and industrial-grade control systems.

4. Project Size

Residential electricians handle individual homes, while commercial electricians work on larger projects like office buildings and manufacturing plants.

5. Regulations and Compliance

Both types of electricians must adhere to strict safety standards. Commercial electricians face additional regulations due to the scale and complexity of their projects.
