Powering Your Backup Generator

You will need a power transfer switch when you want to patch a backup generator to your power source or home electrical system.  When you use a transfer switch, you do not need to run extension cords from the inside to the outside of your house in order to power your generators.  This causes less danger since cords are vulnerable to the elements.  For instance, they are exposed to natural elements such as rain and insects and if they are damaged, not only will they not work, but they are also dangerous.

When you need to find a switch for your generator, you generally have two choices.  You can get a manual transfer switch.  Just as the name implies, you have to manually operate the switch in order to switch power from your primary power source to your backup generator.  Fortunately, it is set up so that you cannot accidentally operate both power sources at the same time, which can cause lots of damage to the electrical circuits.



You can also choose an automatic power transfer switch.  With this switch, you do not have to be present in order to switch from one power source to another.  Rather, the switch senses when there is a power surge or potential power outage.  It will then begin to power up the backup generator.  If the primary source fails, the backup power will automatically kick in.  If the problem passes, nothing will happen.  This type of switch is quite convenient should you be away from your home when the power goes out.  You do not have to worry about food going bad in the refrigerator or pipes freezing in cold weather because the furnace failed.

In most cases, you are probably required to have an automatic switch when you have a home generator, so you do not have to choose between an automatic or manual switch.  Furthermore, the switch is probably included if you have a stationary generator.  You will usually need to find a switch if you have a portable unit.  The one major pro for the manual switch is that it typically costs half as much as the automatic switch.

No matter what type of generator you have, you will need to find the right power transfer switch to operate it.  You should consider where and why you need the generator in order to help you determine which kind of switch is right for you.  If you need the convenience and flexibility of powering your home even while you are away, you may want to look for an automatic switch.  However, you should also check with your local regulations to make sure you get a transfer switch that is in compliance.
