Phone devices were damaged because a best (outgoing) connection to earth was via wires already earthed by a 'whole house' protector (installed for free by the telco on everyone's phone line). Outgoing to earth via devices connected to a properly earthed protector, installed for free, on all phone lines. ![]() To have damage, electricity also must have an outgoing path to earth. A direct lightning strike far down the street is incoming to everything. And properly earth what actually causes hundreds of thousands of joules to harmlessly dissipate outside - 'whole house' protection.Īny protector that degrades or must be replaced after a direct lightning strike is typically undersized and often costs tens of times more money compared to the well proven 'whole house' solution.Ĭlick to expand.Assumed: damage was on the incoming path. ![]() Informed homeowners upgrade earthing to meet and exceed code requirements. Meanwhile, if the phone is a risk, then so is a dishwasher, microwave, dimmer switches, LED bulbs, clocks, and everything else. Damage occurs on the fewer items that also make an outgoing connection.ĭisconnecting is consider ineffective since most surges occur long before you might disconnect. What is damaged? That surge is incoming to everything. If the surge is not connected to earth BEFORE entering, then it will go hunting for earth ground destructively via anything inside a building. Does not matter if utility lines ore underground or overhead. Protection means that surge does not enter the house. Those protect strips only claim to protect from surges tyically made irrelevant by what is already inside the charger for that iPhone.

Potentially destructive surges can occur maybe once every seven years.
