Review on 💥 Leviton 32120-1 120/240V Single Phase Surge Panel, DHC & X10 Compatible, 80Ka L-N Maximum Surge Current by Michael Tran

Installed by an electrician a year ago. This surge protector is designed for ANY single phase 120/240 volt power supply that is universal for single family homes in the United States except for some large mansions which sometimes have three phase power. I can't imagine why an electrician would say that this unit is not only suitable for domestic single family use or commercial use. (Some large apartment buildings are also three phase, typically 120/208 volts. These are typically large apartment buildings, not small townhouse style apartment complexes. This protection is not rated for three phase.) In my case, in my house, the power comes underground to the meter , and there are three main switches directly connected to the electricity meter. These boxes with the main switches are located on the street, next to the electricity meter, on the side of the house. So the electrician installed a new small 2-pin waterproof junction box directly on the meter where this surge protector is connected. This must be performed by a licensed electrician and connected to the terminals on the load side (consumer side) of the meter. This surge protector is housed in a waterproof case and suitable for outdoor installation. It is important that this surge protector is connected to the mains and not to an indoor circuit breaker box, and the cable from it should be as short as possible. Main service for the defender. There are three switch boxes in my house. Each of these boxes is powered by one of the main circuit breakers described above. In each of these boxes I installed a secondary Leviton surge protector (55175-SSA). Each box had two switch positions available, so I installed secondary protection on separate double pole switches. Designed to be installed after one like the Leviton 32120, the 55175-SSA protects the home from minor surges coming from the main protection device. If your home is more traditional, with a main switch connected directly to the electricity meter. , I still recommend installing this surge protector on the meter. You will need a licensed electrician to do this. The electrician, like me, needs to install a small watertight two-pole junction box directly on the load side (utility side) of the terminals of the meter box where the line filter connects. This will make it work much better than plugging it into the electrical box in the house. I live in Southeast Florida, the lightning capital of the United States. Since installing this unit I have had absolutely no issues with surges damaging equipment and have never bothered to unplug during a lightning storm. Additional comment 17 December 2012: Despite other comments, I strongly recommend a meter and not in a breaker box indoors UNLESS the breaker box is on an interior wall directly opposite the meter where there are few between the meter and the mains Wire breaker box feet. The meter will stop any surges of current picked up by this device before they reach your junction box. The low cost 55175-SSA, installed in the control box, absorbs the smaller transients that pass through the Leviton 32120-1-120/240 when there is significant cable length between the meter and the control box. Update October 4, 2018: This has been fixed as I haven't had any issues with the devices in my house being damaged by power surges. Still holds up after 6 years.
