Generac pre-wired automatic transfer switch
Generac automatic standby generator
Generac is one of the United State's leading producers of generators and other back-up power supplies. In addition to building the power supplies, Generac also manufactures accessories such as transfer switches. An automatic transfer switch automatically swaps to a back-up power supply when the electricity to the home is not functioning correctly. Most Generac automatic standby generators come with a pre-wired automatic transfer switch. This means the only wiring necessary will be to connect the transfer switch to your home.
Call your local codes office to make sure it is legal for you to install your own transfer switch. Some locations require the work be done by a professional or require an inspection after the installation. After you are sure you can complete the task legally and safely, call your power provider. They will need to disconnect the service to your home and remove your meter.
Place the generator in its permanent location, outside and near the electrical meter. Mount the transfer switch box to the wall using the supplied screws and pre-drilled holes in the metal.
Remove the cover to your meter base with your hand or by prying with a screwdriver. You will see a wire that runs from your home to the base, supplying electricity to your home. Unplug this wire from the base.
Look in the space where the meter used to be and locate the knockout. This is a square or rectangular piece of metal with holes in it. Unscrew the screws holding the knockout in place.
Use the wire disconnected earlier. Run it through the hole on the knockout and connect it to the commercial output conduit on the Generac automatic transfer switch. Replace the knockout and secure it back into place with the screws.
Locate the wire connected to the automatic transfer switch's commercial input conduit. Run this wire back to the commercial output conduit on the meter base. Close and secure the cover of the meter base.
Ensure the pre-wired connection on the generator is still connected to the accessory input conduit on the Generac automatic transfer switch.
Call your local building codes office for inspection if required by law and then you can have your electricity re-connected.
Working with electricity can be very dangerous. If you are not comfortable and somewhat knowledgeable about electrical wiring, installing an automatic transfer switch is best left to a professional.
