OK, time for a stroll down Memory Lane...
Back in time installation of 'outlets' using zip cord, stapled to baseboards and thru walls was common. Matter of fact, Eagle/Leviton made 'devices' for 'surface wiring'.
The device was wired; forget polarity & that 'ground', Screwed to the baseboard, and extended where 'outlets' were wanted. Some installs were 'tapped' off of a duplex, not plugged in.
Light fixtures were installed like Sedesigner1 describes.
Those were the days!! ??
