We know the neutral and hot lines are completely interchangeable on purely resistive loads, so this has never made sense to me.

    Today I learned the answer. I was listening to APC’s White Paper Podcast episode number 21: Neutral Wire Facts and Mythology. Apparently the reasoning is something like this: Lamp sockets expose charged electrodes which are accessible to fingers, which is against the US Electrical Code. Because of this, it’s necessary to minimize risks by ensuring the live electrode is the button contact at the bottom of the socket, where it’s less likely a finger will touch if the socket is live and without a bulb.

    Interesting, huh?
