Generator Information

When purchasing a generator, it is important to become familiar with the styles and options available on generators.

Portable Generator - If purchasing a portable generator, do not buy any less than 4,000 watts. A portable unit is desirable because it can be transported to other locations. It is also handy for tools on construction sites where electricity is not present. This is the lowest cost option.

Stand-by Generator - These units are mounted outside. They are need to be hooked up with a transfer switch which safely connects the generator to the home wiring without fear of back feeding onto the EMEPA lines. Incorrect connection can harm or kill others.

What fuel options are available to power a generator?
Gasoline
Propane/Natural Gas
Diesel

Gasoline is a readily available and relatively inexpensive method of powering a generator. Gasoline also offers the most power per weight unit and works in most common generators. However, there can be condensation problems in cold weather, and gas generators may require more frequent maintenance.

Propane generators usually require less frequent maintenance, and have no condensation problems, but can be slightly more expensive. Natural gas generators have the same qualities but are slightly less efficient.

Diesel offers low maintenance, fuel-efficiency, and is quite easy to acquire. Diesel generators do, however, tend to be noisier, fuel may be more expensive, and these generators can be more difficult to start in cold weather.

How does it connect to my home wiring?
Generators can connect using an extension cord through an open window or transfer switch. Transfer switch eliminates the risk of electrical "back feed" injuring utility workers repairing downed power lines.

Steps to properly using a portable generator

Step 1: Find a safe location for your generator in regard to CO emissions and refueling. (NEVER use in a garage or under a porch). Check air filter, oil and fuel level prior to use. Generator should be on level ground.

Step 2: Use a heavy duty cord (preferably 12 gauge), with adequate length to reach necessary electrical appliances. Have extra extension cords on hand to avoid overloading. When routing cords through windows, use towels to fill the air gap.

Step 3: If generator has a main breaker, connect the extension cord(s) to the generator with the breaker in the off position. If generator does not have a main breaker, do not connect the generator until after starting.

Step 4: Start the generator and allow engine to warm for 60 seconds. Close the main breaker to power appliances. If generator does not have a main breaker, first insert plug in generator, then plug in each individual load item.

Step 5: You should plan in advance how you want to utilize your emergency power. If you do not know how to calculate how much load to place on your emergency generator, contact EMEPA for advice.

Safety Checklist for Portable Generators

Be sure the generator you have selected has ample capacity to supply the lightning, appliances and equipment you plan to connect. Consult an electrician or EMEPA for assistance if needed.

Purchase your portable electric generator from an established dealer who can provide service and maintenance if needed.

Read the manufacturer's instructions thoroughly.

Use your portable generator outside to avoid dangerous exhaust fumes.

Do not operate your generator while standing in wet conditions. This could cause an electrical shock to anyone who comes in contact.

For personal safety, make sure your generator is grounded so it does not become electrically charged.

Only connect appliances directly to a portable generator. Do not connect the generator directly to the wiring system in your home or other building through outlets or your meter. This may damage your wiring system or back feed electricity endangering utility workers restoring your line.

Do not attempt to fill the generator's fuel tank while it is operating as the gasoline may ignite.

Do not tamper with the engine speed adjustment. This could cause overheating and cause a fire.

Have a charged fire extinguisher nearby as a precaution.
