SO, connecting 200 devices into 4 dual outlet receptacles which all reside on a single mains 15Amp circuit is not a good idea? say a major NO NO?
Even if total draw at any one time is less than 15AMPS?
How about a 12 AWG 25 foot outdoor extension cord behind shelves and filings cabinets to get power to the diagonally opposite side of the room?
There are buildings old enough to have only one breaker for all receptacles and one breaker for all the lighting. just charging all the 5v devices alone uses ten or so outlets. computers and peripherals? then comes an electronics lab, local lighting. video lighting. Photo Lighting power packs, A/V equipment, (kitchen and bath outlets on separate GFCI circuits), and more in this age
