Instead, it rises and falls from 0 volts to 169 volts. This is not any problem for most electronics sold in the country because they are designed to work with this form of electricity. In the event the power exceeds the 169-volt maximum voltage, there is said to be a power surge. The surge or spike in voltage may damage lots of the electrical devices located in the home.

• Surge protectors should meet the UL Standard 1449.
• In a thunderstorm, even the best protection could very well be overwhelmed. The safest choice is to unplug devices if you expect a potential surge.
