STAND BY GENERATORS INSTALLATION NORTHERN VIRGINIA
A generator can make the difference between living comfortably and being stuck in the dark. There are many choices for generator back up power systems, so it is important to ensure you purchase the one that is best for your business or home.
At Galaxy Electric LTD., we can install the following types of systems:
- Self-contained transfer switches: These are the quickest way to provide safe generator power to your house. These transfer switches can provide backup power to 6 or 10 circuits and are mounted next to your existing circuit breaker panel. Your gasoline-powered generator plugs in to a “power inlet” and then you manually switch the circuits on. An electrician is needed to install these manual transfer switches in order to assure the safety of your installation. When our electrician comes to your home, you will choose where your generator will plug in when the power goes out. He will be needed to install the wiring between your generator and the transfer switch. When your power goes out, you just bring out your generator, plug it in, start it up, and transfer your circuits using the installed transfer switch. These can be installed in less than a day.
- Stand-by generators: These are used when you want your generator to turn on automatically. These are permanently set in your yard, plumbed into a natural gas line, and have an automatic transfer switch installed next to your electrical meter. For typical houses, the generators will run on either natural gas or liquid propane. These generators range in size from 10kw to 25kwl; therefore, a load calculation needs to be performed on your house to determine what size backup generator you will need for your home.
When deciding which generator fits your home and family, consider these factors:
- Is oxygen or any type of life support being used in the home?
- Do we have any prescriptions that need to stay refrigerated?
- How often does my power go out?
- What do I want on when my power is off
- How long do my power outages last on average?
- Am I comfortable manually setting up and refueling my generator?
- Do I have natural gas in my home?
How do I decide which Generator is right for me?
This is one of the most important questions you can ask yourself when you are installing a Generator. Generators come in different sizes. You can have anything from a small 10 kW system, which will put out about 42 amps, to a 38 kW generator, which will put out about 153 amps!
To put things into perspective, on 42 amps you will be able to run your basic appliances: your refrigerator will be able to stay on, but you won’t be able to use your electric stove or oven. You won’t be able to have your air conditioner running but you will be able to use some lights and your television or computer.
On a 38 kW generator, you will be able to run more things at one time. You would be able to easily run your air conditioner, as well as, your refrigerator, your lights, your television, and still have some power left over. Most homes have a main electrical service (coming from PEPCO or Dominion) that is typically between 100 amps to 200 amps (some even go as high as 400!).
With every generator installation application, surge protection should also be a part of your installation plan. During power outages and running on generator power, electrical surge protection is recommended by most manufacturers.
