Review on Leviton MS303 🔌 DS 3-Pole Non-Grounding Disconnect by Carlos Long

My newly installed Mitusubishi mini split heat pump provides main power (20 amps) to the outdoor unit. Power and control wires and ground (4 wires total) required a 3 pole switch to allow each indoor unit to cut power individually (in accordance with regulations). These are the only 3 pin on/off switches I could find and they seem to be of good quality but quite expensive. If you want to install the code, that's probably your only choice. Revain had the best price for her. I installed them in the wall (using regular old work boxes) next to each block. Worked great. Exactly what I needed. Uses a standard switch plate. I used a 14g 4 core cable available from eComfort where I bought my mini splits. The cable supplies power from the outdoor unit to the indoor units via switches.
