Review on Leviton 51110 1: Ultimate Protection for Commercial and Residential Spaces by Stanley Molden

The device provides surge protection at the main electrical panel before being distributed throughout the home. Highly recommended by several DIY experts with TV. Worth the money if it saves a large electronic equipment repair bill. Ensure there is room on the breaker panel to add a 2-pole (240V, 30A) circuit breaker dedicated exclusively for surge arresters. The LEDs indicate that the protection is active. A strong overvoltage can permanently destroy the internal protective varistors, so check the device status displays from time to time. Easy to install for those familiar with electrical connection panels. Ask a professional to install this if you don't know what you're doing.
