How do you prove a power surge?
- The device's clock or lights are flashing.
- The device is off or does not work.
- There is an acrid, burnt odor around the device or power source.
- A surge protector or power strip may require resetting.
Are power surges covered?
Renters insurance typically covers damage caused by power surges that result from a lightning strike. Power surges that are generated by an artificial current may or may not be covered. Ask your agent or check your policy to see if certain types of power surges are excluded from coverage.
What is considered a power surge?
The power flowing through the typical wall outlet is considered 120 volt AC power. The voltage is not delivered at a constant 120 volts, however — it can fluctuate between 0 and 169 volts. During a damaging power surge, the voltage exceeds 169 volts.
What appliances are damaged by power surge?
If the voltage is too high it's called a surge, and the mini blast can definitely damage equipment and appliances. The most vulnerable are things like TVs, computers or other electronics plugged into the system, and landline phones.

What are the main causes of power surges?
There are several causes for a power surge. The main reasons are electrical overload, faulty wiring, lightning strikes, and the restoration of power after a power outage or blackout.
Can you feel a power surge?
Even if you don't have visual symptoms of wiring issues, you may still be able to diagnose the problem through your home's outlets. Typically, an outlet that's connected to faulty wiring may be warm to the touch. Similarly, you may feel a vibrating sensation.

What is an example of a power surge?
Power surges occur when the flow of electricity is interrupted, then started again, or when something sends electricity flowing back into the system. Surges can range from five or ten volts when you turn on your hair dryer to thousands of volts if lightning strikes a transformer.
What is a power surge at home?
A power surge, also called transient voltage, is simply an unexpected increase in voltage. If strong enough, it can damage or even destroy electronic devices in your home. Most power surges come from inside the home.
How strong is a typical power surge?
Power surges can range from as little as one volt over the threshold maximum of 169 volts to thousands of excess volts, such as when lightning strikes power lines or a transformer.
What would cause a power surge?
Power surges can originate from the electric utility company during power grid switching. Another common cause of power surges, especially the most powerful ones, is lightning. Power surges can also originate inside a home when large appliances like air conditioners and refrigerator motors turn on and off.
What can a power surge damage?
But when a power surge occurs, it causes a flow of electricity that spikes above 169 volts, resulting in an arc of electrical current. This arc generates heat that is damaging to electronic components and circuit boards. You may not notice damage to your devices after a small power surge.
Can a power surge damage a refrigerator?
When there is an increase in voltage from a power surge, it causes an inrush of electrical current within the refrigerator. This surge generates an excessive amount of heat, which can damage multiple parts of the refrigerator.
What appliances can be plugged into a surge protector?
Small, cheap appliances like lamps, can be plugged directly into the wall. But bigger or more important items, as well as appliances that require constant power, such as computers, printers, televisions, and refrigerators, should all use surge protectors.
Can a TV be damaged by a power surge?
A power surge can damage a TV. The damage can be minimal, such as a single HDMI port no longer working, or it's possible that it could be completely fried and no longer able to operate. A surge protector is a simple device that will add a layer of protection to any devices connected to it.
