Electric Generators

Electric generators are used to supply power to homes, commercial and industrial establishments when there is a disruption of power. It is also used in places where there is no supply of electricity. Electric generators come in a wide variety of models, size, and prices. Choosing the right electric generator depends upon an individual’s need. A homeowner first has to identify the appliances to be powered by the generator. The total wattage required to run these appliances has to be added up, including the starting wattage requirement of some of the appliances such as refrigerators. This makes up the total wattage power required from the generator. Lights and other smaller appliances require 120 volts of power, whereas appliances like electric stoves and driers require 240 volts. It should be checked whether the generators have the necessary voltage ratings.

There are few features that have to be considered before buying an electric generator. First, make sure to check to see if the engine has an overhead valve. An engine that comes with an overhead valve start easily, last longer and is less noisy. Second, check whether the engine has a cast iron sleeve in the cylinder to protect the engine from early wear and tear. In addition to this, electric generators come loaded with many convenient features such as electric start, power switch to alternate between 120 and 240 volts, low oil shut down that shuts the engines when the fuel in the tank reaches a certain level and an hour meter to show the duration of time the engine has been running. Electric generators are generally powered by gasoline, diesel, propane or natural gas. There are inexpensive but have a short life. Diesel generators are fuel-efficient, have a longer life but are relatively expensive. Propane and natural gas generators are best suited where fuel is ready available.

Certain precautions have to be taken while using generators. They should always be located outside the house to prevent exposure to harmful carbon monoxide. They should always be kept dry and should not be touched with wet hands to avoid getting electrocuted. Generators should not be refueled when in operation -- spilling of fuel on hot components may cause fire. It is always wise to invest in a good quality generator. Electric generators can be purchased at any appliances or hardware store. Industrial and commercial electric generators are available with their respective dealers. All brands and models of generators are listed on the web sites.

RV Generators

RV generators are what truly make your RV fully self-contained. What a feature, instant electricity at the push of a button. We take electricity for granted in our homes because we don't have to do anything to get it, with the exception of paying our monthly electric bill. This is part of the problem with RV generators, we expect the electricity to be there when we need or want it just like in our house. The problem is this magical source of electricity requires a certain amount of care and maintenance from the owner.

Safety first! Always keep in mind when you use a generator there is carbon monoxide. You should always inspect the exhaust system on the generator set before using it. Do not operate a generator with a damaged exhaust system. If you're using a portable generator set make sure the exhaust is directed away from the camping area. Test your carbon monoxide detector for proper operation prior to using the generator. Never run a generator when you or anyone else is sleeping. Observe campground etiquette. Do not run your generator after quiet hours.

A generator that comes equipped on an RV gets its fuel supply from the same fuel tank the engine uses. When the fuel tank reaches a 1/4 tank of fuel the generator will shut down to prevent you from possibly using all of the fuel without realizing it. The generator will either have an automatic transfer switch to sense whether you are using shore power or the generator, or you will need to plug the RV power cord into a generator receptacle to use the generator. It is perfectly okay to use the generator while you are traveling.

This is one of the reasons you have a generator in the first place. It is actually more fuel efficient to run the generator with the roof mounted air conditioner on, than to use the dash air.
