During an outage, many individuals sometimes use a backup generator for electricity. While this standby power option is a handy one, an improperly-installed generator can be both destructive and dangerous.
The 2 most important steps to follow when using a generator are to:
- Install it with a proper regulator so that it doesn’t overpower or damage your appliances
- Isolate it so that it can’t feed electricity back into power lines causing serious harm or death to a line crew working to get the power back on
Purchasing the Appropriate Generator
- Never use a gas-powered generator inside your house or garage due to the danger of carbon monoxide poisoning
- The generator’s output is rated in Watts
- To determine the size you’ll need, start by totaling the wattage of the lights and appliances you’d like to power
- Check the labels or owner’s manuals for each appliance’s rating
- Then, add about 20% as a reserve to handle the increased start-up power requirements
- Example: if you want to power at least 2 fixtures on a general-lighting circuit (240 watts, when used sparingly), a sump pump (1500 watts), and a refrigerator (600 watts), you’ll need a generator that can handle 2340 watts
Installing a Regulator
- Installing a regulator will control the charging rate
- If you plan on operating sensitive equipment like televisions and computers from the generator, also use a surge protector
Isolating Your Generator
- To isolate your generator, plug the appliances you want to power directly into the generator with the appropriate-sized cords
- Install a double-throw switch that disconnects your home from the Co-op’s system
Always follow the manufacturer’s recommendations on how to use your generator
