What’s The Difference Between Commercial and Residential Electricians?

Electricity is so essential that one could argue that we would struggle to even maintain our civilization without the electricity we have come to rely on. Yet, it is also something that we often take for granted. Different buildings require different electrical loads to be delivered. And when something’s wrong, we need to make sure we call a specialized electrician.

You might be wondering, but isn’t an electrician just an electrician? Not exactly. There are different types of electricians. The foundation of the skill might be basic electrical knowledge. Still, their wiring work is different in terms of the equipment used, load demands, and energy needs. They also follow other procedures and materials. 

Differences Between Commercial and Residential Electricians

Type of Wiring They Handle

Residential homes tend to use a thin gauge of wire that is then insulated in a simple plastic sheath. Many of these wiring sheaths are colour-coded. When it comes to commercial locations, the wiring needs to be robust. These thick gauge wires are contained in durable tube-shaped conduits that pass overhead through ceilings or protected subfloor spaces. 

Power Levels

Residential and commercial properties have different power load requirements. Residential buildings use what’s called “single-phase power”, which is a 120 Volts electrical current. Some appliances, like refrigerators, require a “two-phase circuit” which delivers 240 Volts. 

In commercial properties, a “three-phase design” is used. This means that two smaller legs supply 120 Volts as well as a third, which operates at 208 Volts. This type of design offers excellent efficiency while helping extend the life of large commercial equipment.

Codes and Standards

Residential and commercial electrical systems are expected to meet different standards. Commercial wiring must stand up to high levels of heat and corrosive substances. Some commercial buildings are also required to have generators as backup systems. In residential systems, the main concern is to keep the homeowner safe.


There are different types of licenses for electricians. Each license specified the type of project a contractor can do and the monetary size of the project. Contractors with a class A license can work on any project. Class B license allows working on projects under $120,000 in value. Class C license holders can work on projects worth $10,000 or less.
