I'm planning to connect a 5000W single-phase inverter and I want an easy way to disconnect it without wiring directly to the load center. I'm not considering an upgrade to 240V in the future. Would it make sense to use a 14-50P plug for the inverter and a 14-50R receptacle at the load center, as long as I'm consistent with using one hot wire on both ends? I've seen warnings online saying this isn't a good idea but I think it's more about safety for future workers, which isn't a concern for me. I've looked into 5-50P/R connectors, but they seem pretty rare. Any advice or suggestions? Just trying to learn more about this!

What exactly are you planning to disconnect? If it’s for solar panels or something similar, there are specific disconnect boxes designed for that. They can help isolate inputs and outputs effectively, which might be a simpler solution for your needs.
Using just one hot wire on a 14-50 outlet isn't code compliant, so keep that in mind. But if you're okay with non-compliance, a 5-50 outlet is definitely an option, even if they're not super common. You might find it easier to find 14-50 or 6-50 plugs though! Just make sure you're clear on the connections to prevent any confusion in the future.

Yeah, I get that the code compliance is more about safety than actual danger for you. Just be cautious when setting it up, and maybe mark everything clearly for anyone who might look at it later!
