how do you know he's using power strips? he could be using multiple outlets that are on the same 20amp breaker. plus, if you have the ballast plugged into the outlet then i really don't see anyproblem running the rest of that gear on a powerstrip. that's only 300w of gear which is like 2.8amps. most power strips are rated for 15 amps and you won't experience any voltage drop or heat issues running 3amps through them.
sorry total...my bad. i wasn't paying attention.
hey bud, sounds like someone is upgrading. sweet dude. what you need from the electrician is gonna depend a lot on the equipment that you use. for example; are you using 240v ballasts or 120v? what other equipment do you have in each room? what size is the current breaker for the outlets in the room. a lot will depend on these answers. also, are you trying to do this for as cheap as possible or are you willing to spend some extra money to have it done a little nicer?
how are you running 3,000w on a 30 amp timer panel? are they 240v ballast cords? 1000w ballast pulls 10 amps at 120v and 5 amps at 240v. then you have 3 inline fans and a 12,000btu a/c all on the same circuit? you sure?
i'm not talking about what you run your panel at (it wouldn't be a subpanel if you ran it at 120v; would be a glorified powerstrip). i'm talking about what you run your equipment on. you have 60 amps at 120v on a 240v 30 amp subpanel. 3 ballasts are 30amps. 3 inline fans are 6-8 amps. 2 amps for the wall fans. 10-12 amps for the a/c unit. that's around 50 amps which is 83% of your capacity. any electrician will tell you that is MAX load recommended on any circuit. most say stay around 75-80% of your rated load to be safe.
wow...you are a fun one to deal with. good luck with that degree...while you are at it try socializing with some people on campus toolbag. sorry i was off by 5 whole amps. what a jackass. you just proved my point. i'll talk to you any way i want; it's an internet forum so stop acting like you can do something about hero boy! feel free to stfu now.
numbers are numbers, theres right and theres wrong. and when it comes to electrical you damn right that 5 amps matters.
duh ass clown...i guessed the electrical draw on your 3,000w grow based on some assumptions. obviously i'm not gonna be dead on! i don't know what type of ballasts, fans, a/c you are using. what are you? retarded? socially handicapped? you are at the max recommended load for your subpanel. not running at "less than half the capacity." THAT MATTERS! you were wrong.
usually the bulb sits in a reflector or hood. it's screwed into a migul socket. then a cord goes from that to the ballast. ballast make heat so most people keep them outside the room. that's why most mogul cords are 10-15 feet. then the ballast plugs into the wall outlet.
