Wiring Your New Commercial Building, From Start To Finish

So you are constructing a new office building. During the early stages, electrical contractors are brought in to assess the needs and locations for electrical power. In an office building, electrical wiring has to be sufficient throughout the building in order to provide power to all of the computers, printers, phones, lights, security systems, etc. The electricians begin their work the minute the building's framework is enclosed. It is a very long process where the electricians are concerned. From start to finish, here is how they do it.

Running Cable

The electricians have to run miles and miles of electrical cable through the building. These cables run through the walls, up and down vertically, and then across the grids that will become the ceilings of each floor. The cables are uncut until the electricians can connect them to power boxes and grids. Then the cables must have enough length to run to individual outlets.

Installing Power Boxes

Power boxes may all be located on the first floor of your new building. However, most electricians choose to have a separate electrical box/fuse box for each floor and located in a utility closet on each floor. If that is the case, your electrical contractor will build the electrical systems on each floor individually, and work up from the ground floor as the construction contractors build and add floors going up. The power boxes have to be installed in order to connect all of the wiring and cabling to the power boxes. Then the electricians move on to connecting the wiring and cabling to the outlets in the walls and floors of each level of the building, They also have to install the lighting at this point, too, but that typically does not occur until after the construction crews start putting in the framework for the dropped ceiling and trayed lights.

Connecting the Switches and Outlets

Outlets and switches are practically the last step in the process. The electricians install all of the outlets and switches in the walls and floors after the paint, drywall, and plaster have been installed and applied. When all of the necessary outlets and light switches are fully wired, the power is turned on, and the electrician checks everything to make sure it is working. If everything checks out, then the electrician waits until a building inspector arrives to examine everything. If the building inspector states that everything passes and is up to code, the electricians' job is complete. If not, the electrician has to fix what is wrong. Then the job is done.
