Severe weather can come unexpectedly, leaving you and your family without power for several hours or days. Planning ahead for these extreme conditions with an electric generator can help keep power your essential electric devices and appliances. The size and type of generator will depend on how many items that you want to keep power to.
We will walk you through the different types and styles of generators, so that you can be prepared in case of a power outage at your home.
Choosing the right generator before the power goes out in your home
There are essentially three ways to keep electricity running to your home, in case of a power outage.
1. Portable Generator
These generators can have either gas, diesel or propane for fuel. Their smaller size allows them to be moved around fairly easily, depending on the size.

- Not portable
- Environmentally friendly
- Zero carbon monoxide
- Can be used indoors
- Portable
- Budget friendly
- No fossil fuels to operate
- Can be used for camping, hunting, construction sites and RV's
- Has to be recharged when its power runs low
- Difficult to recharge during severe storms and power outages
How to determine the size of generator that is needed
Before choosing a generator to backup your home during a power outage, there are some calculations that need to be made to ensure that the generator is large enough for you needs. To determine right size generator for your home, recreation or work, you need to know your power wattage that will be used. Generators are sized and rated by power output, as measured in Watts. Depending on what are wanting to operate with your generator will determine how you calculate the watt ratings. Starting watts and running watts are the two types of ratings to consider. Starting watts are extra watts needed to start an electric motor, such as a refrigerator or circular saw. Running watts, or rated watts, is a continuous wattage that is needed to keep the item running.
To determine your wattage requirements:
- Make a list as to what you'll need during a power outage, in an RV or at a jobsite. Select the items that you would like to operate at the same time.
- Make a list of the running watts and starting watts for each item. You can find these ratings in the owners manuals or the data plate on the appliance.
- Add together the RUNNING WATTS of all of the items (that don't require starting watts) that you want to operate at the same time. Multiply this number by 1.5. This is the minimal size of generator that is required.
- If you have some appliance that require STARTING WATTS, then will have to figure in an additional step when making your calculations. Add together all of the RUNNING WATTS of the devices that you want to operate at the same time. Find the device with highest STARTING WATT rating and add that number to your total RUNNING WATTS. Multiply this number by 1.5. This is the minimal size of generator that is required.
Electric Generator Safety
SAFETY FIRST:
While a portable generator can be a lifesaver, it can also be dangerous if you don't take precautions. People tend to buy generators during major storms. In a rush to get it up and running, they might skip over critical safety steps while setting it up. Dozens of people die every year from carbon monoxide poisoning related to generators. We don't want you or anyone relying on a generator to be one of those people.
Here's some safety tips for setting up your generator:
- Always operate a generator outside at least 10 from your home with the exhaust pointing away from the house.
- Never store the fuel can next to the generator. The slightest spark could cause a fire.
- Don't cover or lean anything against the generator while it is running. The exhaust gets hot and may catch combustable materials on fire.
- Don't operate a generator near a door or window
- NEVER operate a generator inside of a house, building, garage, carport or awning.
- Install a carbon monoxide detector in your home prior to using a portable generator. It will detect you if carbon monoxide from the generator exhaust gets inside your home and reaches unsafe levels.
Connections from a generator to your home
1. Portable Generator
Before attaching cords to a portable generator, make sure that it is on solid level ground. Move fuel cans at least 20 feet from the generator and follow the safety guidelines that were listed previously.
- Extension cords
Running extension cords from your portable generator to your home is the least expensive way to get backup power to your home during an outage. Make sure that the extension cord is at least a 14 gauge and is rated to handle the wattage of the device/appliance that you are operating. Hooking up too many devices/appliances to a single extension cord may trip the breaker on the generator or may damage the device/appliance.
- Sub panel
- Transfer Switch
When using a sub panel, a transfer switch is also installed to prevent electricity to feed back into the main power lines that supply the home. It is used for the safety of the utility workers. Without a transfer switch, a portable generator can enough electricity to injure or kill a utility worker that is trying to fix a damaged power line several miles away. A transfer switch is easy to operate. When there is a power outage, simply flip the switch from UTILITY position to GENERATOR position before connecting and starting the generator. After the main utility power has become restored, then flip the switch back to UTILITY position and unhook the generator.
2. Standby Generator
Since a standby generator is not portable, it is recommended to decide on a location that is at least 5 feet from any doors or windows. Set the generator on a pre-cast concrete pad that is supported by a compacted bed of rock. Secure the generator to the pad with 4 stainless steel bolts.
- Sub panel with transfer switch
- Natural Gas/Propane
3. Portable Power Station
Connections to a portable power station can done quickly. They don't require any fossil fuel to operate, so you can operate them inside of the home without the risk of carbon monoxide poisoning.
- Direct connect
- Extension Cords
- Sup Panel with a Transfer Switch
Make a plan
Severe storms can be frightening and very stressful when the power goes out. Climate changes have been producing stronger storms, which is causing more power outages and overloads on the power grid. The uncertainty of the longevity of an outage can take an emotional toll on you. Using these guidelines will help you prepare for the worse and give you a better piece of mind.
