- Weather Protection: Cover your generator with a weather-resistant shield to protect it from water and maintain its functionality.
Portable vs. Standby Generators
Portable generators are great for moving around and suit campers or job sites. They weigh less and most models offer 2,000 to 7,500 watts. You need to start them by hand and plug in what you need.
Standby generators stay put and start up by themselves when there's no power. They typically produce 5,000 to 20,000 watts, enough for a whole house. They cost more upfront but are easier to use since they work automatically.
Think about how often you lose power or if you might during bad weather. A standby generator is good if that happens a lot.
If you only need a generator now and then, a portable one should work.
Adapters and Extension Cords: What You Need to Know
When using a generator, choose the right adapters and extension cords to connect appliances safely:
- Power Rating: Check that the adapter or cord can handle the generator's wattage to prevent overheating.
- Length: Use a long enough cord to keep generators away from buildings, but remember that very long cords can lower performance.
- Type of Plug: Make sure your plug fits the generator's outlets. Some need twist-lock adapters.
Before using, always check cords for damage and avoid using multiple cords together.
Quality equipment ensures safety and efficiency during power outages or when using outdoors.
Installing a Transfer Switch
A transfer switch connects your generator to your home's electrical system, allowing safe electricity flow during outages.
First, pick either a manual or automatic switch. Manual switches need you to activate them manually during an outage, while automatic switches kick in as soon as they detect a power loss.
Hire a licensed electrician to fit the transfer switch to your main electrical panel. This process may include setting up a sub-panel for circuits you want to keep powered.
After installation, test the system to make sure it works well.
Keep your generator and transfer switch well-maintained to ensure they're ready when you need them.
Choosing the Right Generator for Your Needs
When picking a generator, think about what appliances you need to run, your budget, and where you'll use it.
Here's a quick guide to help you choose:
- Power Output: Check the wattage needs of your appliances. For basic home needs, a generator offering 3000-5000 watts is usually enough.
- Fuel Type: You can choose from gasoline, propane, or diesel. Gasoline is easy to find but mightn't be very efficient. Propane burns cleaner.
- Portability: Decide if you need a portable generator for places like outdoor events, or a standby generator for home use.
