Do not touch a person if a power line is touching them. Call 911 immediately. If a power line falls across your vehicle, stay in the car and wait for emergency personnel to cut the power. If a part of your body touches the car and the ground at the same time, you could be electrocuted. Key Causes of Power Outages Trees or branches knocked down by wind, snow or ice into power lines.
Lightning strikes a transformer or other electrical facilities.
Car accidents where utility poles are knocked over or sway enough to knock the lines together and trip off the circuit. Equipment overload, especially on hot days when air conditioning is cranked up, or during extremely cold weather when electric heaters are turned on all over the system. Digging too close to lines or cutting a line. Sometimes, the outage is a result of a circuit overload within your own home. Check your fuses and breakers first.
