Hi!
I'm renovating the studio and was wondering how to find out how many fuses i need per outlet.
I'm currently using elinchrom digtal rx 2400ws.
At minimum you want to have 20 amps a circuit.
If your remodeling talk to an electrical company about having at least another 100 amps run to your studio (200 is preferable) and then go through a distro box.
Standard 15 amp house breakers are cheap and prone to blowing under heavy use of if the ambient temperature is high. They also wear out quickly with age.
This is just one option
http://www.bhphotovideo.com/c/product/4246...ed_Through.htmland do a google search under distro boxes and you'll find a lot of options. A professional distro box will last a long time and Mole stuff may be ugly but I've used some Mole Boxes on movie lots, that I am sure were used for Gone With The Wind and they still work fine.
You can run 100 or 200 amps into a distro box, then three pin connectors out to edison or any type of connector so you can run hot lights when needed.
You can never have too much power, even if your running low wattage lamps, because hair and makeup can draw more power than a 5k.
Even in studio with proper amps I keep two honda 2000 generators on standby and it's saved me a few times when power goes down or you want to run some lights through a studio window and it's a lot easier to just run a generator than cross back and forth with 4 stingers all running around the set.
Also if you go to pro 7's you must have heavy duty extension cords (stingers) as pro 7's without the right extension will only let you go to half power with standard home depot stuff.
RGH in NY has them, their expensive but well worth it.
http://www.rghlighting.com/Be careful of cutting corners on AC power. A cheap box, a bad breaker, flimsy stingers and it's not only a time killer it's not too good for people either.

P.S. I guess I have to mention medium format for this post to be legal, so uh . . . well if you shoot medium format you will need more amps for the same amount of depth of field you will get with a dslr. So look into those 100 amp boxes.
