Tri-State Generator Alliance
On the left see the side hill stone pad framed in 4x4's. Note there is nothing exposed. The natural gas pipe and the electric runs are trenched and buried in conduit. Also note we did not use inexpensive direct burial cable. The system is 5' away from any windows and vents. If for some reason you cannot trench and bury the right shows the correct way to run electric and fuel lines along a wall and penetrate the wall. They are secure, safe, and organized.
On the left. This is what a well organized and safe transfer switch installations look like. This is to code in every way. On the right is a smaller residential Kohler unit. Note the stone pad framed in 4x4's. This is the correct way to build a stone pad preventing shift and promoting good drainage. The machine is level and safe.
Same job we hoist the generator in place with a crane and place it on the pad. This was a 60kw Kohler Light Commercial System.
On the Left we cut a driveway so the high voltage, low voltage, and natural gas pipe could be buried. All are in separate conduit and will last a lifetime. The driveway was back filled and re-paved. On the right we constructed a concrete pad that will not move or shift. Notice the conduit for the electric and gas come up through the pad. There will be no exposed wires or pipe.
