With services from a commercial electrician in San Jose , you can rest assured that your wiring, industrial lighting, and other electrical features have been safely and properly connected to the electrical grid. Before you embark on your commercial electrical system installation, it is a terrific idea to gather some basic information about how these units work. Here is an overview of what you need to know about commercial power systems. 
Electricity Is Supplied By the Power Company
In order to provide electricity for your commercial building, your electrical contractor will start by connecting your building to the municipal power supply. The power company is responsible for transporting electricity from the power plant to your building. Typically, large commercial spaces receive around 13,800 volts of power to their grids. If you have a smaller building, your power company may need to adjust your voltage to a lower level.
Small Buildings Receive Simple Distribution Systems
The type of electrical distribution system that is installed in your building is dependent on the overall size and square footage of your facilities. If you are constructing a smaller commercial building, your electrician may recommend that your wiring, panels, and devices are connected directly to the transformer. In order to allow you to control your building’s power supply, your electrician will also install several circuit breakers. The circuit breakers will control the power flow to each branch of electrical components.
Large Buildings Require More Complex Systems
When an electrical system is created for a large and complex commercial building, it will be necessary to create an electrical system that is capable of handling a larger power load. Owners of large commercial buildings may also be responsible for purchasing and maintaining their own transformers. From the transformers, the electricity passes through a switchgear and then a circuit breakers. Your electrician can help you decide what type of commercial electrical system will be appropriate for your building.
