Generator Guidelines

Summary: This helpful generator sizing and selection guideline will help you consider the generator size for the best value when selecting your home generator.

Generator Guidelines for Sizing a Home Generator System

Use this generator sizing guide to help select the right home generator.

There are a wide variety of home generators to choose from so here are a few guidelines to follow while your looking for the best value. Select a brand that has the features you need at a price you can afford.

Look for pre-wired, pre-packaged solutions, that extend your value even further by making the generator system the absolute easiest to install.

Make sure the generator has an industrial grade engine that is specifically designed for the harsh rigors of standby power, with easy motor starting capability and a enclosure design to protect your generator and your investment.
