How to Hook a 4500 Watt Generator to My House
Home generators can provide power to your house in the event of an electrical outage. A 4500 watt generator will give you enough power to run a small air conditioning unit, refrigerator, lighting and some small appliances. Wiring the generator to your main circuit box is dangerous and must be done by a licensed electrician. Safety laws require connecting your generator to a manual transfer switch or similar device, to prevent power being released back into the electrical grid.
- Consult a licensed electrician to help you choose a manual transfer switch to install on your main circuit box. The amperage of the switch must match the amperage of your power cord. A six circuit switch will be enough for a 4500 watt generator. An included wattage meter will help you track the power being used and prevent any overload.
- Call the local electric utility to have your installation approved and receive a certificate.
- Obtain a permit from the city to install your generator if necessary.
- Schedule an appointment for a licensed electrician to come out and wire the generator to the transfer switch and the main circuit box.
- Test the transfer switch once everything is wired to make sure it is working.
- Ask your electrician about the possibility of installing a cheaper interlock device, instead of a manual transfer switch.
- Automatic transfer switches are more expensive but will automatically switch to the generator when city electricity goes down.
