More Electrical questions (amperage watts etc...)

[Blunted22]

Hey guys i finally got the new permanent spot and getting my electrical ran and all that good stuff. This is what i got

2 rooms 1 veg 1 flower (of course) I go a sparky over at the house as i type this installing me 2 30a breakers and runnign 1 to each room on a 4 plug box. i also have 1 20a thats old house wireing thats hooked up to all the upstairs lights and plugs. THe catch is that it doesnt have any ground running to them (dont know what this really means for me.) Does that matter on what i can run off that? should i not run lights or anything?

I got a OLD window AC that run you turn it on itll dim the lights so im scared to really do anythign with them outlets can you let me know what will be safe to run on them?

My next question was what can i run on the 30 amps safely? i know i cant run 2 1000w on 1 20a but can i run 3 1000w on a 30a breaker? My guess is no but i dont know the math to actually know for sure. I know a 1000w is 9.5 amps and you have to be at 80% of full capacity to be safe. So im guessing 28.5a on a 30a breaker wont work lol. is 24a all i can run ona 30a breaker (i think the math is right)

Anyone know the amperage for a 400w and 600w ? Can you run 3 600w on a 20a safely i know if you can itll be pretty much at full cpacity but i dont know the correct amps for a 600w

can you explain how i would do that? can it be done if the 30a 120v all ready ran upstairs ?? Is there a converter or something like that?

Im not the smartest with electrical yet

hey man thanks alot kudos on the advice that was some of the most helpful shit ive got in a long time and the catch is that its easy -=P maybe you might know this question also?

If i switch that to a 240 it cuts the amps i use in half right? so i 1000w is usually 9.5a but at 240v its only 4.1 (actually more then half). so on a 30a breaker if i switch it to 240v i can run 5760W safley on that one breaker?
(30A * 240V = 7200W and 80% safe usage is 5760W)

So can i really just run 5 1000w on this one breaker?


dude if this is how this going to work man im gonna be happy as fuke. lol

You had an electrician run the circuits so I'm assuming he pulled #10 AWG sized wire for the 30A circuit.I've seen stupid shit man,especially from residential electricians(no disrespected intended to all you romex jockeys lol).Anyway unless you know for sure never ever go by a breaker rating until you've verified branch circuit conductor size,it's actually the most perfect recipe for fire you can come up with.Undersized wire for breaker rating...Please check.

hit he better used the right sized wire i payed more for it and stressed it to him repeatedly. So if i switch them to 240v then do i have to switch anything in my ballasts? or how does that work?

You have to change the wiring in your ballast. It's all in there and easy to do, unfortunately I have never done it so I can't explain how to accomplish this. I am sure somone here knows and will chime in shortly. The ballasts I own have a switch on them that let me change from 120 to 240. As a bonus they also have a switch that lets me change between HPS and MH. I love these ballasts, I wish I could find more!
