You can save thousands by opting for a portable generator. One of the first decisions many homeowners make when deciding on backup power is whether to use a portable or a home standby generator. It is the only safe way to connect your generator directly to your home. This is why a transfer switch is required by the Australian Licencing Authorities for any connection of power to a home. There are many different kinds of transfer switches available.
Manual vs. Universal Transfer Switches
You’ll also want to consider how to connect the generator to your home safely. Write down these instructions and put them in your breaker box. Green - Ground to the power inlet box.White - Common, W terminalBlack and Red - Load - either X or Y terminal.
Setting up the Generator to House Wiring
Dedicate one cord to each appliance to prevent overloading the circuit, and secure your cords with properly rated conduit, shielding, or tape. You can also safely draw power through your home’s circuitry by using a generator interlock kit. This cost-effective, legal alternative to a transfer switch is a manual, mechanical device that is relatively less expensive to procure and install. The interlock is a metal or plastic guard or bracket that allows the generator to feed electricity into your home’s circuitry while keeping the main circuit breaker switched off. It covers your service panel to deactivate the main power supply while the generator is running, and it blocks the flow of power to and from utility lines when the generator is on.
Step 9: Prep Breaker Box for Wires
And, unlike a home standby unit, you can take a portable generator with you if you move. I've listened to and have even seen people using a double male plug to energize their house during a power outage. A generator is a core component to many people's emergency preparedness plans. (Maybe you have a cool charcoal powered or a multi-fuel generator.) However many fail to think through how exactly they will power the items they want to run when the grid is down. Now, let’s look into the limitations of having home standby generators compared to portable ones. Remember that plugging in a generator safely is crucial; one wrong move and it’s not just lights out—it’s danger knocking.

Everything may operate on generated power as easily as it does when using utility power. When the test run indicates problems, there are a few things to check. Also, these generators demand careful wattage calculations before use. You need to know exactly which devices you’ll power up to avoid overloading the system. Next, we’ll go through each step of safely connecting a generator using one of these switches. Always check local codes because rules differ on connecting generators safely without risking lives or breaking laws.
The Danger of Back-Feeding Electricity Through Wires
Remove one knockout and screw in conduit adapter or in my case a blue non metallic conduit adapter. Fill any gaps between your conduit and the house with silicone or expanding foam. I bought 10 feet of 10 gauge wire in black, red, green and white.
The generator is now connected to the house and ready to provide power. To use the MTS, you simply throw the switch to the generator position and start the generator. This will provide power to the circuit breakers that are connected to the standby generator. The MTS is a simple and effective way to wire a generator to a house. However, it cannot power the entire home unless the generator is designed to do so.
The switch feeds electricity into branch circuit breakers in the breaker panel and prevents it from flowing into any other circuits. Switching off the main breaker before connecting a generator to your house will prevent power from feeding utility lines, but the setup can be hazardous. If the breaker is inadvertently turned on, there are no safeguards against energizing utility lines or electrocuting people or pets in the home. The generator supplies electricity through two 120-volt lines. If the generator plug is pulled out of the outlet, anyone who comes into contact with the terminals will be shocked. If the main power comes back on, back-feeding electricity into a convenience outlet can overload your circuits, damage your electronics, and overheat wiring to create a fire hazard.
Don't Use a Double Male Plug
Installation of a transfer switch is generally done by an experienced electrician, since it involves moving around the wires that enter your home’s circuit breaker board. However, installation can also be done by homeowners with some experience with electrical wiring and most transfer switches come with clear installation instructions. A transfer switch is an electrical control device that you install directly alongside your home’s circuit breaker box. The main purpose of the transfer switch is to switch your home’s electrical grid off of the utility electrical grid and onto your generator. An interlock device is an alternative to transfer switches that make it possible to plug into a service panel directly.
Most boxes will have enough spare wire to move things around a bit. If you do not have enough room and your breaker is 30 amps or less you can use a short piece of insulated wire and a wire nut. You will need to pick up a wire splice at your local home store. If you buy fuel in bulk to last for several days or longer, use fuel stabilizer to slow the fuel's chemical degradation.
Typically these are installed on the exterior of your home to make it easy to plug in your generator in order to safely connect it to your home. The house cannot be connected to both the generator and utility power at the same time – the main breaker transfers power from one source to the other. In order to connect power to the generator, you’ll need to neatly run wires through the conduit towards the inlet box. Be careful and try to pull one wire through the conduit at a time to make the best use of the tiny space.
