Electric systems are subject to disturbances that cause momentary or extended power outages.
Most outages are caused by natural events - storms, animals touching wires or tree branches brushing power lines. Accidents and equipment failure also cause outages. No matter what the cause, your business will do better the more you know and prepare. Momentary outages, such as when lights blink, actually protect the electric system from severe overloading and increase overall service reliability. This is made possible by devices called reclosing circuit breakers or reclosers.
