How did they manage to connect what I assume is 14 AWG solid wire to a plug that is designed for maximum 16 AWG stranded wire???
I mean...those plugs are used for small things like lamps and TV sets and small-to-medium duty use appliances; certainly NOT for this!
I'm thinking that trying to bend those wires around the terminal screws would have probably cracked the rubber housing of the plug.
Oh...and if anyone wonders what the wall plate to the right of the outlet is in Shot #5, It looks like a connection for a TV antenna -- 300-ohm twinlead type.
At least that's what I've seen them labelled in places like Radio Shack - back when they still sold that stuff.
Talk about a PROJECT!
