A generator that’s too large, on the other hand, may be an unnecessary expense. The goal is to find the right balance, ensuring that your generator can efficiently power your home during an outage. Here is our suggestion for the top generators for emergency home backup.

Factors to Consider When Choosing a Generator for 200 AMP Service

Choosing the right generator involves more than just looking at wattage. You need to consider several factors to ensure you’re making the best choice for your 200 AMP service. Let’s dive into the key aspects you should keep in mind.

Power Requirements

Before you select a generator, it’s important to calculate your home’s power needs. This means adding up the wattage of all essential appliances and systems. Start by identifying which devices you need during an outage—like refrigerators, heating systems, and lights. Each of these appliances has two power levels: starting wattage and running wattage. Your generator must cover both.

Phase: Single-Phase vs. Three-Phase Power

Another critical factor is the phase of your power. Most residential homes use single-phase power, which is sufficient for standard appliances and systems. However, if you have a larger property or special equipment, you might need three-phase power.

Understanding whether your home uses single-phase or three-phase power is key to choosing the right generator. For 200 AMP service in a typical home, a single-phase generator will usually be enough.

Fuel Type and Availability

The type of fuel your generator uses is also important. Common options include gasoline, propane, and diesel. Gasoline is easy to find but can be less efficient over time.Propane burns cleaner and stores longer, but it may require more storage space.

Diesel is reliable and fuel-efficient, especially for larger generators. Consider the availability and storage needs of each fuel type to choose the best option for your situation.

Generator Type: Standby vs. Portable

Lastly, decide whether a standby or portable generator is better for your needs. Standby generators are permanently installed and start automatically during an outage. They’re powerful and convenient but come with a higher price tag.

Portable generators are more affordable and can be moved around, but they require manual operation and fuel management. For a 200 AMP service, a standby generator is often the best choice for whole-home backup.

Determining the Right Generator Size For A 200 Amp Service

Choosing the right size generator for 200 AMP service is critical to ensuring your home has enough power during an outage. The size of the generator determines how much electricity it can provide. If it’s too small, you’ll struggle to power everything you need. Let’s explore how to figure out the perfect generator size for your 200 AMP service.

Calculating the Right Size

To find the right generator size, start by calculating your home’s total power needs. Add up the wattage of all the appliances and systems you want to run during an outage. Include essentials like your refrigerator, heating or cooling systems, lights, and any medical devices.

Remember that some appliances have a higher starting wattage, so account for that too. For 200 AMP service, you typically need a generator with at least 15,000 to 20,000 watts. This size ensures that you can run most, if not all, of your home’s critical systems without overloading the generator.

Common Sizes and Their Capabilities

Generators come in different sizes, measured in kilowatts (kW). For 200 AMP service, generators in the 15,000 to 20,000-watt range are common. A 15,000-watt generator can handle most essential appliances, while a 20,000-watt generator provides even more coverage. 

The larger the generator, the more appliances you can run simultaneously. If you want to power your entire home, including luxuries like a central air system or multiple refrigerators, go for a 20,000-watt generator. Otherwise, a 15,000-watt generator should cover most basic needs.

Sizing your generator correctly is key to keeping your home powered smoothly during an outage. Whether you need to run just a few essentials or your entire home, understanding your power needs and choosing the right generator size will ensure you’re prepared.

Installation and Safety Considerations

Once you’ve chosen the right generator size for your 200 AMP service, the next step is to think about installation and safety. Proper installation is crucial to making sure your generator works correctly and safely. Let’s break down what you need to know to get your generator up and running.
