A whole-home surge protector is a device that’s installed in your electric circuit breaker box or main point of power entry to your home. A surge arrester will help protect your electronics from internal and external power surges. Most electronic devices are rated for 120 volts, but a major...
The appropriate application of surge-protective devices (Figure 8) will lessen the magnitude and duration of voltage surges seen by the protected equipment. The problem is complicated by the fact that insulation failure results from impressed overvoltages, and because of the aggregate duration of repe...
