This install took place in Cold Spring Harbor, NY. We installed a under ground 499 propane tank that site 25 feet from the generator. Followed by a full house standby generator system with load shedding circuits. This was a 400 Amp service which we installed two transfer switches. One acts like a slave and the other switch. The generator is about 100 feet away from the house, all PVC is buried and runs underground. The propane tank sits near the driveway. It is a easy to fill and easy to check the level for future fills type of setup. This is a clean install and it functions perfectly!!!
