  • The “120 volt cable”, assuming you mean NM-B aka Romex, is rated for up to 600 volts if you look at it closely. It is absolutely acceptable to use that wiring for a 240V circuit, as long as you wrap colored (not green) electrical tape around the white neutral wire to indicate it’s another hot.

    Yes, there are 3-conductor (plus ground) wires one can also use for switches and 240V circuits with neutral. That neutral can be used to have 120V and 240V together (your oven may use 240V coils, but the light bulb probably runs on 120). Doesn’t mean you need to have it, if your 240V circuit doesn’t need a neutral. My air compressor is just a motor that can run at 240, no neutral needed, and its outlet is wired up with the same kind of Romex used for a 120 right next to it (with black tape to indicate a second hot)




  • I worked in the airline industry for years and learned a GUI overlay for one system and another entirely green screen system called SHARES (see if you can guess the airline). Honestly I kind of enjoyed working with those systems; there’s some refreshing “back to basics” feeling kind of like driving a manual transmission.

    In my current job I’ve been using another legacy system. Well, my job was to create a relatively modern service for the legacy system to call, but none of the remaining developers knew how to use the extensions of that system that does SOAP calls. So I had to learn just enough of that legacy system to hold their hands through the parts that call my service. Kind of fun, to be honest!
