  • If this is the fixed version, “kw/h” isn’t a thing. Well, technically it is but doesn’t mean what you think. The unit for energy is kilowatt hours, or kWh. No “per” to be seen.

    Kind of like how torque is measured in foot pounds, not foot per pound.

    Sorry, I’m just an EV nerd who sees people make that mistake all the time and gets a little twitchy about it



  • I am subscribed to this community and I largely agree with you. Mostly I hate AI slop and that the human element is becoming an afterthought.

    That said, I work for a small company. My boss wanted me to look up AI products for proposal writing. Some of the proposals we do are pretty massive, and we can’t afford the overhead of a whole team of proposal writers just for a chance at getting a contract. But a closely-monitored AI to help out with the boilerplate stuff especially? I can see it. If nothing else, it’s way easier (and maybe better results) to tweak existing content than it is to create something entirely from scratch










  • 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)
