Review on Leviton 42120 1 Protector Protection Commercial by Tim Ross

Added when I installed a new electronic washer and dryer. My electronic dishwasher is also safer now. NOTE: Does not pass home automation signals as it rejects noise too well. Get a cheaper model for less noise cancellation. It is necessary to connect two 120V disconnect switches as close as possible to the protection. $500 spent on it is a great guarantee that you won't need an expensive service call for burnt electronics. Your TV, DVR, computer, microwave, refrigerator, etc. will be protected.
