Service Entrance Surge Protection

January 12th Fact-of-the-Day

Electric service entrance surge protection is important both to human safety and to the protection of all electrical and electronic devices in a home or office from lightning damage. However, very few older homes and offices have service entrance surge protection devices installed in most parts of the world. They are available in several forms. Some are designed to be installed outside at the base of the electric power meter. Some are designed to be installed inside the main circuit breaker panel. Others are designed to be installed at, but outside, the main circuit breaker panel. Some only protect against electric power surges. Others also provide incoming telephone and cable TV line surge protection. All types require low-impedance, high-current-capacity ground circuits for proper operation. Though they may seem somewhat expensive, their cost is relatively trivial compared to the value they protect. ©2005 Martek International All rights reserved.
