[Shop-talk] Determine NEMA outlet type if it’s plugged in?

[Jim Franklin]

I’m dealing with a bunch of Schroedinger’s outlets here. All the outlets are in use so I can’t unplug them to look at the NEMA marking, but I need to replace the devices plugged in, which can be ordered with various plug types. Is there a way to tell from the outside what type I have? It’s round, which narrows it down to a few…

Thanks,
Jim
