Remember to turn off all of the breakers in a manual transfer switch so that they’re ready to go when the next power outage strikes. To be prepared for an outage ahead of time, it’s possible to leave your generator connected to the transfer switch all the time. Otherwise, since you’ll be moving around in the dark during an outage, it’s a good idea to keep the generator cord located with your generator or transfer switch.

Carelessly switching on all breakers across the board can overload a small generator, so be sure to go one circuit at a time. Switching back to main power has to be done manually also, so skimping on installing interlock switches can cost you in wasted fuel and time, as well as shortening the overall lifespan of your generator. Ensuring your safety is not an afterthought—it’s a critical step in integrating a portable generator into your home’s circuits.
Manual vs. Universal Transfer Switches
This bad boy is between our generator and a specific, reserved plug-in spot on the transfer switch. Always shut off the main circuit breaker before starting any wiring work. If you’re like me, the thought of a power outage leaves you cold – literally! That’s why knowing how to wire a generator to your house is important.
Connecting a Portable Generator To a House
If you're using an inverter, and you only need to power a couple appliances like a refrigerator and some lights, a proper extension cord will do the job. Buying an emergency generator is a great first step in protecting your family from power failure. But, even the most diehard prepper cannot predict the next power outage.
Disadvantages of Portable Generators
In addition, shut down the generator and remove the power plug. Now Switch ON the main MCB (Main Switch which is connected to the main power supply). The transfer switch won’t let go the power to energize the generator or power company wires e.g. it turns off the power supply that could come from the breaker in the panel. Keep in mind that only those breakers and load points will work which are connected according to the above (illustrated purpose) wiring diagram.
The first and most important step is to determine which appliances and devices you need to power. This will help you determine the size of the generator you need as well as how to wire it. This method is more involved but will provide you with power even if the generator is not plugged in. Depending on your circumstances, it makes sense to buy a 240 volt extension cord with the correct amperage for your generator.

Now, let’s look into the limitations of having home standby generators compared to portable ones. Wear rubber-soled shoes and use non-conductive tools when working near electrical systems. Never operate a generator in wet conditions; water conducts electricity and increases shock risk.

They stop dangerous back feeding where the electricity goes the wrong way down utility lines. Heath first showed a manual transfer switch, which designates specific circuits to be powered in the event of an outage and has to be manually switched from utility power to generator power. While it is possible to connect your portable generator to your house without a transfer switch, it is VERY DANGEROUS and NOT RECOMMENDED! Doing this can cause a fire and even electrocution – do not attempt to connect your generator to your houses’ electrical system this way.
With 12,000 starting watts, this dual fuel generator can run on propane or electric and has an electric start and low-oil shut off. People have gotten creative building all kinds of cobbled-together shelters to protect their generator from wind, rain, and snow. Assuming that they don’t get blown down or collapse, that’s all fine, but keep a five-foot air space from the generator to surrounding surfaces; this prevents overheating the generator and reduces the risk of fire. If you prefer a turnkey solution, you can buy a manufactured cover to run your generator in inclement weather, such as a Gen Tent. Finally, many generators are equipped with CO detectors that will shut the machine down before CO builds up to the point where it becomes deadly.
According to Portable Power Guides, they are against code in some areas — especially residential zones. For further troubleshooting information, go to the owner’s handbook for your generator. Read up on utilizing your generator before an emergency strikes since generator safety is crucial.

His well-researched guides and insightful articles have become a go-to resource for both seasoned professionals and eager DIYers looking to enhance their skills and tackle their projects with confidence. Our advice is to stick with well-known generator brands, particularly those by manufacturers that belong to the Portable Generator Manufacturers Association.
Portable generators come with limits (see the basics of portable generators for more info). They can’t power heavy appliances like stoves, air conditioners, and dryers due to their low output. This means during a blackout, you might still be in the dark about how to cook or stay cool. Just as guarding against electric shocks is vital, addressing fire hazards is equally crucial when connecting a generator to your home.
First of all, of course, flip the main circuit breakers to OFF (OPEN) position. Remember that the panel may become energized from utility, so wear rubber gloves! Take a sufficiently long generator cord with 4-wire plug and bolt red and black leads to the “hot” bus-bars (the thick vertical metal plates) after the main double-breaker. Be sure your connection is downstream from main disconnect and not upstream.
Make the investment, and install a back-up power transfer switch or a Generlink meter mounted transfer switch. This little guy is essential – it keeps your generator from sending power back into the grid. Installing a transfer switch involves connecting it directly to your home’s electrical system.
In this video, This Old House host Kevin O’Connor explains how to install a stand-by generator. Let’s delve into the nuanced trade-offs that define these power solutions, dissecting their strengths and weaknesses to illuminate your path in securing an emergency energy plan tailored to your needs. Make sure this matches up with the needs of the home appliances that you want to power. It’s equally crucial to keep up with regular maintenance and follow best practices to ensure its longevity.
