Thank you for your suggestion. I have an uncle with a multimeter but he wasn’t sure about testing a 250v outlet, and the guide I found instructed to start testing by flipping off the circuit breaker, so I started looking for that. But I’ll be looking into this Non-Contact tool. I really appreciate the advice.

Thank you very much. I’ll be looking into this tool. I really appreciate the advice.

Unfortunately the chart is unhelpful. Either ambiguous naming, or “girl’s room” type stuff. And no one is aware of what those designations mean anymore (people moving in and out and having done this or that random work themselves or with some random person they happened to know). But I definitely will be updating the labels ASAP.
