The failure was due to poor contact and heating that melted the first or second socket because these two sockets have to carry all or almost all the current in the circuit and if the wires don't enter the push-in straight or have burrs that don't allow them to seat properly you get a loose contact that gets worse over time. (Tenured faculty), PyQGIS: run two native processing tools in a for loop. What to do during Summer?

Why do some stay on, while others can shut off completely if 60V is passed on. Hopefully you will find the bad connection right at the panel but if it is more involved, I strongly recommend doing that rather than looking for voltage with the circuit live. I changed the receptacle and it didnt help. Unlike AC, if the polarity is reversed DC gives a reading of 0 so I would see inconsistent readings depending on how I was hooking up the leads.
