Pre-Installation Process

Prior to installing your commercial or residential standby generator, we’ll obtain all permits and authorizations. Permits or authorizations may be required from the city.

We’ll also visit with you about the best place to install the generator, keeping noise and your beautiful landscape in mind.

The Installation Process

The installation process starts with prepping the area where the commercial or residential standby generator will be located. A concrete slab will then be poured to meet manufacturers’ specifications including stub ups for all electrical connections.

Once your concrete has cured, the generator can be put into place. How we put it into place is determined by the size of your generator. An off-road forklift is needed in many cases.

Once the generator is in place, we bolt the unit to the concrete slab. With the generator in place, it’s now time for electrical and plumbing. Our electrician will dig a trench to run all electrical underground. The transfer switch will then be mounted on the wall and all conduits will be connected together. All electrical wires will be pulled through the conduit. At this time we’ll cut off all electricity to your home or business. Electricity will be off for about an hour. Once all electric connections are made, we’ll restore your power.

Now it’s the plumber’s turn. We’ll dig a trench from the generator to the fuel source. Plumbing will be installed in the trench. All plumbing will meet or exceed manufacturers’ specifications. We will "tap" into the fuel source of your choice (natural gas or propane).

All connections are made at the generator and proper gas pressure will be set using a regulator. At this point we’ll hook up the battery. Once this is done, we are ready to start the generator.

We’ll perform a "start up" on your generator. A start up consists of making sure the engine is running at peak performance and testing for proper voltage and frequency. (Only a qualified technician should attempt this.) When your generator is running properly, we’re ready to transfer load to the generator. This will be done in small increments. As a load is applied, we’ll continue to monitor the voltage and frequency as well as watch the amps that your home or business is pulling. (We never want to overload the generator.) Once the "start up" has been finished, all warranty paperwork will be filled out and sent to the manufacturer (Generac).


The time needed for installation will depend on many factors: the authorizations and permitting, the size of your generator and equipment, the number of engineers needed to install it, the inspectors’ schedules, and the weather.

“Generator Supercenter service was very professional. The installation crew was courteous and neat. When the installation was done the house was spotless. The owner from Generator Supercenter was always accessible for questions and kept us up to date on all phases of the project. Our family has a feeling of security knowing we are protected from the next power outage. I am recommending Generator Supercenter to my friends and family.” Susan Gerald, Houston, Texas
