Generator Transfer Switch Review

A generator transfer switch is an electrical switch that’s responsible for delivering the power from your portable generator to your home’s electrical system, when there’s a power outage. Installed beside your main electrical panel, you can install a transfer switch to provide power to your most critical circuits (like your refrigerator or lights). Or your entire electrical system (subpanel). Generator transfer switches are not sold with generators so you need to purchase one on your own.

You’ll see that there are both manual and automatic transfer switches available. By far, manual transfer switches are the most common type used by homeowners. And they’re economically priced.  If you have a manual model you’ll have to activate the switch yourself if you have a power outage. But an automatic model senses when you’ve lost power - or regains power – and reacts for you.

Generator Transfer Switch Types – Which Size is Right for You?

How do you know what generator manual transfer switch size you need? The easiest & best way to choose the right size is to look at your power cord. The power cord connects your portable generator to your transfer switch.

Take a look at the amp rating on your power cord.  And match it. If you power cord is rated for 30 amps, you’ll need a 30 amp transfer switch.

And when you shop around, you’ll want to choose one with the right number of circuits for your portable generator. Generally speaking, the average 5,000 watt generator can usually give you power to six circuits in your home. So you’ll want to choose a transfer switch with six circuits. But if you have a larger generator, say 7,500 watts, you’ll probably be able to power 10 circuits. And you should buy a 10 circuit switch so you can power more devices/systems in your home.

And please think about safety! I can’t tell you how important it is to hire a licensed electrician to install it. Please don’t try to do it yourself. 

When the electrician installs your new transfer switch next to your electrical panel you have two options: you can hang it on the wall, like a painting. And this is the cheaper option. Or you can recess it into the wall, if design or style is important.

Now you have the right information to choose the correct generator transfer switch for your home!
