Residential Versus Commercial Electrical Wiring

While all wiring may look the same, there are some key differences between residential and commercial electrical wiring. From the electrical codes and energy demand levels, to the grade or quality of materials, and wiring installation environment, every aspect varies between a residential or commercial electrical setup. In fact, not every electrician can do both types of work. Residential electricians go through licensing and certification from the relevant local and state agencies. Commercial electricians not only need to complete their certification, but also a commercial electrician apprenticeship program before they can take on jobs as licensed electricians.

The qualified and experienced professionals at J&S Electrical Contractors Inc. share some of the significant features that distinguish residential wiring from commercial wiring.

Top Differences between Residential and Commercial Wiring 

  1. Wiring Types: Residential electrical wires are quite thin as compared to commercial ones. Commercial wiring also features a thermoplastic, high-heat resistant, nylon coating, (TTHT coating) that offers the hardiness needed for commercial environments.
  2. Conduits: A tube or trough that protects and routes the electrical wiring throughout the building, conduits are a key feature in commercial buildings as the wires run through open spaces at several points. Residential wiring is usually plastic sheathed wiring, but does not require conduits. Although residential wiring runs through the walls and attic and comes in contact with other surfaces, the sheath keeps the wires from starting a fire, and protects the occupants of the premises. 
  3. Grade of Materials: The codes and standards applicable to commercial electrical wiring materials are different from the ones for residential wiring. Typically, commercial wires need to comprise of materials that are more resistant to corrosion, chemical exposure, and heat.
