A Spike Guard is an electrical device used to protect electrical equipments from voltage spikes, surges, and fluctuations. These voltage spikes can occur due to many reasons: a Lightning Strike, Fluctuation from the Electricity Provider, or Improper Electrical Wiring. Fluctuations in a power outlet can cause serious and catastrophic damages to the equipment connected to it.
A Spike Guard is commonly used with printers, TVs, refrigerators, computers, laptops and other sensitive electronic devices to protect them from voltage fluctuations. Although it is recommended to install expensive equipment with Voltage Stabilizers, Spike Guards provide an economical protection measure.
Spike Guards are also known as Surge Protectors, Spike Busters, and Spike Boards in India. They can also be used as Power Strips because they have multiple sockets which extend the connection in a single power source to multiple power outlets.
