The Difference Between Commercial and Domestic Electrical Tasks

Commercial & Domestic Electrical Tasks

Residential and commercial electrical works vary regarding load demands, equipment setup, and the energy needs. These tasks require entirely different procedures and classes of materials. Furthermore, different types of technicians (domestic and commercial electricians) are needed to conduct each of the two tasks.

Other factors that differentiate these tasks are;


Commercial and domestic buildings need different electrical loads. Residential homes require one power phase: this phase delivers 120 volts of electricity. Three wires are used to supply the power: negative, positive and neutral. Some appliances such as air conditioners, dryers, and refrigerators require more energy in domestic residential. In such cases, 240 volts is supplied using a two-phase circuit.

Commercial buildings are supplied with three-phase wiring design. The design uses three legs; a large one that operates at 208 volts and two smaller ones that use 120 volts. Each leg operates at low workload as it supplies more power to the electrical appliances used. The design facilitates high overall efficiency enabling big commercial machines to last longer.


Technicians conduct all residential installations before the drywall; this hides the pipes and wires behind the building’s walls. Domestic electricians do so because maintenances are rare in local settings. It is, therefore, crucial to conduct correct installation in homes; seek services from a seasoned electrician Oldham for better results.

Ducting or conduits are used for commercial settings’ wiring installations. They are accessible when making alterations, replacements, and repairs. The need for frequent changes is, therefore, well suited when technicians make such installations.

The Wiring Type and Equipment Used 

Domestic buildings and commercial constructions use different wiring when undertaking electrical tasks. In residential homes, electricians use flexible plastic sheathings-encased small thin wires. Since residential environments are open spaces where anyone can access, safety is prioritised. That is why they use plastic sheathing; it also protects the cables from damages.

Ceiling rafters and tube-like conduits are used to contain wiring in commercial buildings. This facilitates safety, wiring protection, and ease of access for the electricians. Most commercial locations tend to get continuously renovated; therefore, commercial electricians tend to do the wiring in easily accessible places. Commercial cables require more insulation compared to the domestic wires; this protects them from liquids and corrosive gases.


The difference between commercial and domestic tasks is deeply technical. The electricians have to deal with different and specific wiring regulations. For this reason, specific highly trained technicians have to undertake each of these tasks. Domestic electricians are responsible for installing electricity, lighting wiring, electric gadgets installation or conducting repairs in residential or households.

Commercial electricians, on the other hand, deal with electrical tasks in big or small industrial environments. Some of their duties include installing, testing and maintaining electrical units and systems in places such as schools, shopping centres or even hospitals. They can be employed to work with health and safety equipment and security systems. Before hiring an experienced electrician, ensure they possess all national qualification for quality assurance just like the guys here at Pulse Electrix.

Domestic and commercial electrical works require different procedures. It is essential to seek services from reputable firms with highly-skilled and specialised electricians for each of these procedures. Such technicians know well how to conduct electrical tasks in different settings.
