Before you can safely connect a backup generator to your house, you must first disconnect the utility power from the house. If this is not possible, a transfer switch should be used. Then, you can safely connect the generator to the house. When the utility power returns, you can reconnect the generator to your house.
Manual transfer switch
When connecting a backup generator to a house, it is important to use a manual transfer switch. This device will allow you to switch your appliances to backup power in the event of a power outage. The switch will allow you to run appliances until the power comes back on. You can install this device indoors or outdoors, depending on your needs.
There are two types of manual transfer switches available. One type is manual and the other is automatic. Manual transfer switches will always have to be checked and maintained. An automatic transfer switch is better for larger properties located in blackout-prone areas because it automatically shifts the power to the other source. However, this type will require additional expense to install. These switches are generally better for public and commercial properties, while manual switches are suitable for small homes.
If a manual transfer switch is used, the manual transfer switch should be connected to the backup generator and positioned so that utility power can still be obtained. This can be necessary in case the utility power feeder breaker has tripped or the utility service disconnect switch has been tripped. In such a case, you should reset the breaker and then re-connect the transfer switch.
The manual transfer switch should match the largest outlet on the generator. It should also have the same ampere rating. Also, it should have a wattage meter so you can monitor the amount of power coming from the generator. You do not want to overload your generator and damage appliances.
If you plan on using a backup generator to power your home, you will need extension cords to connect it to your house. These cords come in a variety of lengths and gauges. Each one has different wattage ratings, and you should choose one with the appropriate AWG.
The length of your extension cord should match the length of the power cord you’ll be using for the backup generator. You should choose a cord that is 25 feet long or more, depending on how much electrical power you’ll need to run your home appliances. If you’re connecting multiple appliances, you should look for one with multiple outlets. Buying a 30-Amp cord will give you more than enough electrical output to power a few small appliances, while a 50-Amp cord will give you more than enough power for your home. Make sure the cord is compatible with your generator’s power outlet, though, as it’s illegal to backfeed electricity from the generator to the home.
The most common question about how to connect a backup generator to the house is whether you should use an extension cord or a transfer switch. Although an extension cord can be used to connect a backup generator to a house, it can be messy and unsafe. A proper generator plug will be much more convenient and easier to use.
An interlock kit prevents power from being transferred from a generator to a house by using a simple metal plate. Once installed, a homeowner should shut off the main breaker and slide the interlock plate away from the breaker. Then, the homeowner can turn on branch circuits individually, making sure not to exceed the generator’s output capacity. Another option is a transfer switch, which reroutes important circuits to a secondary service panel. Typically, a transfer switch is manual, but there are also automatic versions. They can be used to power only selected circuits or to turn off the entire power supply.
A good interlock kit can be purchased online from electrical suppliers. The kit you purchase must be compatible with the electrical panel of your home. Some of the online retailers even guide you through the selection process. Nevertheless, the key is to make sure that you choose one that will protect your home from unauthorized access.
If you are installing the interlock kit yourself, you should carefully check the documentation and instructions provided with the interlock kit. If there are any questions, consult a certified electrician. A certified electrician can install the interlock kit and wire it to your house.
