Ok today i ran into a problem I'am doing 12 plants im vegging under 1200w MH, there not turned up all the way i got digital ballasts on so when i turned it to full power i set off the breaker, but I'am also running 10'000 btu portable A/C so i figure that's easily 1000w alone and 3-fans also. My question is what do i need to do to stop the breaker from setting off, what do i have to upgrade? because once flower comes I'm doing 5200w in my grow room. help plz thanks RiU.

you need least 3 circuits for what your trying to run, most people would build a sub panel and run from that. you could do a 50 amp sub panel for pretty cheap

1x 240v 20-30 amp circuit for the lights
1x 120volt circuit for the fans and what not
1x 120volt 20amp circuit for the AC

list:
50 amp sub panel
50 amp 240v main breaker
50ft 10 awg wire(for 240v circuit)
50ft 14awg wire(for 120v circuits)
tape measure
hacksaw
wire strippers
wire caps
plastic conduit pipe and fittings
x2 20 amp 120 breaker
x1 30amp 240v breaker
DUPLEX sockets(these are the one that 240v plugs) with plastic housing
screws
youll probably need more than that lol.

Poly's got it right. If you are looking to do 5200w+ and you are already tripping the breaker than you are going to need a subpanel or additional outlets in your room off the existing subpanel. Probably larger wire gauges and breakers as well.

The reason your breaker keeps tripping is 1 of 2 thing or both. Either the wire gauge in the wall is not big enough or the breaker is not big enough. 2 600w digital ballasts wired 120v pull about 5.4amps a piece. That's 11amps right there. If your breakers is 15amps like most residential outlets are then there is no way you can run all that equipment on it. My guess is that it is a 20amp breaker which is why you have been able to run the fans and a/c up to this point. Still pretty unsafe. Usually rooms are wired in zones so every outlet in that room is on the same breaker.

If you didn't understand why this was happening then your best bet is to get an electrician to install a subpanel. If you can't get an electrician in there then send me a PM and I'll try and walk you through it. Not easy and might not even be possible; depends on the rooms location in regards to the main panel and the current amps of your service. Also depends on the existing draw of the house.

Rough guess is that if you want to run that 5000w+ in there then be prepared to spend at least $250-$350 on electrical supplies. Maybe more if your room is far away from the main panel.

Phillip and Poly thankyou for your helpful info, this helps alot I'm gonna get an electrician to help me with this. I knew it would be to much power for that room. And the panel is located outside. The room I'm doing this is up stairs but i was gonna relocate downstairs been having a few heat issues, thats why i went out and got the a/c. you guys think it would be better to move everything downstairs since heat rises?

hell yeah. but what ever is more dicrete IMO. plus if you move it to the basement you probably wont need a subpanel just wire the circuits from the box. much easier and cheaper on the pocket

It can get a little expensive if you start having to run wiring all through the house to get it to your grow. Try and grow somewhere where you are close to the main panel. Coming through a wall or the ceiling/floor is not a big deal. Going to the other side of the house can be.
