Preventing Damage Caused By Power Surges

To safeguard residential or commercial structures from unexpected power surges, a device referred to as a transfer switch is used. Transfer switches can be found in several varieties and are ideal for any home or business, especially those located in areas where frequent power outages are experienced. Such devices are particularly beneficial for businesses that may suffer financial loss if power interruptions occur.

Automatic Versus Manual Transfer Switches

Transfer devices change the path of electrical currents from their main power source, typically the local electric company, to a backup generator. Such devices can be automatic or manual; however, switches used in commercial buildings are almost always automatic. When automatic transfer switches are used, no interruption in power is noticed by those in the building when the transfer is made. It is for this reason automatic devices are usually preferred by most business owners.

Automatic switches have additional features such as computer software that monitors electrical power as it enters the building or home. At the first sign of a power surge, or in the case of a complete loss of power, the transfer switch automatically starts a backup generator, which will take over until the software determines that the frequency and voltage coming into the building have returned to normal. When the latter has occurred, the device will switch back over to the building's standard source of power. With a manual switch, these changeovers must be handled by an individual on the scene. While this process is typically lengthy, it saves time and energy that may otherwise be wasted on false alarms.

The Benefits of Preventing Power Outages

The primary benefit transfer switches provide is protection from loss, and although they are often used in residential homes, they are more frequently seen in commercial buildings where a loss of power would be detrimental to the company's day to day operations. For instance, a refrigerated food storage facility that experiences a power outage could potentially lose a significant amount of perishable items, resulting in lost revenue. Similarly, power spikes at a computer company may result in the loss of pertinent information or damage to the company's computers. It is for this reason most business owners invest in such devices.

Wattage Requirements

Whether the device is being purchased for use in a residential dwelling or a commercial building, it is important to choose a suitable model when selecting a transfer switch. For this reason, it is wise to consult a wattage requirement guide to determine the precise amount of power that will be needed should a blackout occur. While there is a monetary investment associated with such devices, most people find that the benefits transfer switches provide are well worth their cost.
