We cannot afford to conduit and hardwire everything in our temp. haunt so Codes state in a temporary attraction only UL approve temporary wiring must be used ,not extension cords.. Is this temp. wiring SO cable ? What guage if so? Does anyone really not use extension cords if this is the case. Thanx Dave

we dont use extension cords. We wire up an outlet by every item that needs to be plugged in. the UL wirnig can be bought at any hardware store like home depot. I believe its around $300 for 500 feet of it or 1,000 feet i dont remember...

About the first paragraph in the wiring code book says :"Work must be done in a workman-like manner".
So stringing 200 feet of armored cable around like spaghettii won't make it, unless your local inspect say it will.??

Per our code, we can use SO wire provided the proper connectors are used. We did "Drops" from the cieling into our rooms and tech areas, we needed to install strain reflief's to get started though approved.

"Out of reach" installation is always the best. Steel conduit with extra strap holders screwed into solid surfaces is what has to happen, unless you think only calm, nice , non-vandalistic people will be your patrons.
Or..have one employee for every ten customers in your house, more lights on, and surveilence cameras. Then the only people not behaving are the criminally insane, or former employees! hahahaha!

If you overhead hang your cables as we did, you can't just let them hang from their own weight. You need to install a braided strap, or "relief" to take the weight of the cable off so the internal wires don't get pulled apart and seperated. You can see an application here at Mcmaster Carr, go to page 810 and scroll to the bottom.
To describe this easily, if you plugged a cable into a ceiling outlet and you yanked on it, it would become unplugged. Now if you hard wire the same cable and yank on it, it would stress the jacket and internal braided wires causing a nasty electrical arc. You can create a loop of extra cable and tie it off about 16" from the outlet and lessen the weight of it with a strain relief. The other kind of strain relief is in every electrical appliance were the cord feeds out of the appliance, these are simple plastic or rubber clamps that keep you from ripping the cord out. Even though that damn computer may desrve it!
