power strips
james_s:
No, it was nothing to do with tripping, these were all located under benches. They specifically stated that fire code prohibits daisy chaining of power strips. There are rules on extension cords too, my friend's shop has had to remove some to please OSHA, an extension cord is defined as a temporary device and cannot be used "permanently" to deliver power to a stationary appliance.

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

Its not that easy... In short circuit event magnetic part of circuit breaker may fail to trip, if loop resistance is too high. In some homes you may find C16 breakers securing wall outlets, meaning in worst case they need 160A short circuit current to trip.

Hi aqstephenson
This is not directly an answer to your question and is more of a general point. Make sure that you get a good quality power strip because the quality varies quite a bit and the lower quality power strips are suspect.
