When the power goes out at home, having a backup generator is invaluable. You can use emergency electricity to keep the refrigerator running, operate medical devices, and ensure the safety and comfort of everyone in your home.
With a transfer switch, you can power your home with a generator during temporary or prolonged periods without traditional utility electricity. At Shop Solar Kits, we specialize in continuous, off-grid power solutions, so we developed this guide for everything you need to know about transfer switches for generators.
What is a Transfer Switch for Generators?
A transfer switch is an electrical switch that switches the electrical load between two sources. In homes and businesses, you can use transfer switches to toggle between utility-fed electricity and a backup power supply from a generator.
Modern transfer switches come in many types and capabilities, but you can generally categorize them into two operating modes: manual and automatic. Automatic transfer switches seamlessly switch to generator power when utility electricity is lost, while manual switches require users to physically switch the home’s source of power.
Residential transfer switches are popular in areas that experience frequent electrical brownouts or blackouts from weather, unreliable infrastructure, and more.
Do I Need a Transfer Switch for My Generator?
Not always, but they are becoming more and more popular, especially if you plan to run your home’s lights and appliances without utility power and/or extension cords. Transfer switches can work for both traditional gas generators as well as solar-powered generators (aka portable power stations).
For gas generators that need to operate outdoors at a safe distance away from people, a transfer switch is necessary to efficiently use the electricity generated from the gas generator in your home. Manual gas generators may require you to go outside and battle the elements in potentially dangerous conditions and often require a hole drilled in the side of your home during installation.
Conversely, solar generators do not emit harmful fumes, so they can be safely run as a portable source of power in your home. With this in mind, the energy from solar generators does not necessarily have to go through a transfer switch to be helpful; however, having the power to operate the appliances in your home is incredibly convenient, making transfer switches very valuable.
Can I Install a Transfer Switch for a Generator Myself?
You can; however, we do not recommend this. We highly suggest consulting a licensed electrician. Transfer switches are high-powered electrical devices that should only be installed by a professional. Not only can you be harmed while incorrectly setting up a transfer switch, but a professionally installed device is the only way to ensure that you will continue to have power when you need it most during a utility blackout.
For the safety of you, your family, and your home, we do not recommend installing a transfer switch without the help of a licensed electrician.
Do I Need a Permit to Install a Generator Transfer Switch?
Yes, you will usually need a permit when you install a transfer switch for a generator, which is another reason why a licensed electrician is necessary. As a physical and electrical modification to your home, any legally existing transfer switch must be permitted by a licensed electrician and approved by local regulators.
Technically, it is possible to install a transfer switch yourself, but most parts of the world require a licensed electrician to approve the safety of your installation before its use. Failure to obtain a permit can result in fines and other civil penalties.
Generator Transfer Switch Installation
If you’re ready to install your transfer switch for a generator, we break down the basic steps below. Today, many transfer switches come with a manual and installation instructions, which should be followed very carefully if available. If not, take the following steps:
How to Use Your Transfer Switch
Once installed, transfer switches for generators are typically straightforward to use. After installation, label each switch and breaker as to what part of the home they power. You can then simply flip each switch to the generator mode to send electricity to each location.
With all of the switches are off, connect the generator to the transfer switch using the generator’s power cord. Be sure that your cord is both long enough to reach your generator (on the ground or raised) and the correct gauge to withstand your intended electrical loads. Once connected, check that your main power line is off before testing your home appliances with generator power.
The Best Transfer Switches for Generators
For homes and cabins, it can be overwhelming to decide which transfer switch to purchase. Not only do they require high-level electrical knowledge, but there are also many transfer switches on the market today from a wide variety of manufacturers. To make it easy for you, below, we highlight a few of the best transfer switches for generators available today.
