I'm helping install a mini-split AC. The manual says I need 10 gauge wire to an outdoor disconnect switch. I've two questions:
- What does the NEC say about the min height of the disconnect switch when mounted to the wall outside? I know I need 3ft clearance in front of it, but not sure about minimum height.
- I haven't decided which to run (MC or NM cable) from my main panel to th e outdoor disconnect switch, but regardless, when it gets outside of my hou se, what does the NEC say about how the cable should be run? I assume in m etal or plastic conduit? Any other allowable alternatives?
All advice, and NEC references, appreciated. Thanks Theodore
