Domestic and commercial electrical works can differ in regards to equipment setup, energy needs and load demands. These jobs tend to require completely different methods and classes of materials. Additionally, different types of electricians are needed to conduct each of the two tasks.

Other factors that differentiate these tasks are;



Electricians carry out all residential installations before the drywall; this hides the wires and pipes that are behind the building’s walls. Domestic electricians carry this out because maintenance is rare in local settings. For this reason, it is critical to conduct correct installation in homes; seek services from a seasoned electrician Oldham for better results.


Domestic and commercial buildings require varying electrical loads. Domestic homes need 1 power phase: this phase delivers 120 volts of electricity. 3 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. Sometimes 240 volts is supplied using a two-phase circuit.

Commercial buildings are supplied with a 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 a 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.


Electricians have to deal with different and specific wiring regulations and because of this highly trained technicians have to carry out 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.
