Commercial and residential electrical wiring are completely different in terms of energy needs, load demands, and equipment setup. They also require different classes of materials and procedures.
Integrity Power and Electric specializes in Commercial and Industrial electrical work. Let’s look at some of the differences:
Commercial electrical wiring normally uses a three-phase design. In three phase electrical systems, there are two smaller legs running 120 Volts each and i wider leg running 208 Volts. This setup allows each wire less workload, while creating a higher output when they work together.
This leads to greater efficiency and longer lasting equipment.
The higher voltage requirements are due to the increased power demands in an office environment. Commercial wiring often has a higher level of insulation, known as TTHT (Thermoplastic, high-heat resistant, nylon coated).
This helps to protect the electrical wiring from corrosive gases and liquids. In some cases, special outlets may be installed for power-hungry or especially sensitive equipment.
Commercial and Heavy-Duty-Grade Devices
In some locations, such as hospitals, a higher grade of outlet is required to provide power to sensitive equipment. These devices are much more durable and are rated to work in a wider temperature range and in environments with corrosive or chemical hazards. Most of the commercial and heavy-duty grade devices are also impact-resistant, to provide a long service life in heavily used commercial applications.
