Before you buy a generator or a transfer switch, you’ll also need to understand the electrical needs of your home. Whether you purchase an automatic or manual generator transfer switch, there are a number of factors to consider before you make your purchase, from the type of generator you own to the sizing of the transfer switch. A manual transfer switch is cheaper, but it must be installed separately and may be a hassle to switch on and off during an outage.
Though an automatic transfer switch is more expensive, it is more convenient for the homeowner because it works automatically and is installed by the electrician along with the generator itself. Stationary backup generators are installed with an automatic transfer switch, but portable generators require a separate manual transfer switch.
A generator transfer switch allows you to automatically or manually transfer your home’s power source from the electrical grid to the generator when the power cuts off. Without a generator transfer switch, however, generators are difficult and often dangerous to use. Both portable and standby generators can keep you and your family comfortable and safe during a power outage or emergency.
