I have an unwanted 240v outlet in my hallway, on the same circuit as my sewer pump.
I pulled the cover and the box is an old work type. I noticed a junction box in this area of my crawlspace, so I suspect this breaker is controlling both.
Now, to my question: How can I safely remove this plug from service, while keeping the sewer pump active?
They don't make child safety stuff for 240v receptacles that I've seen, so I'd like to just get rid of it. Is it safe to remove the plug, cap the wires and put a blank plate over it?
