i have 2 seperate rooms 1 for veg the other for flowere both are 8+8+8 I use two 400 mh and 1 hps should i have seperate breakers put in or should it be ok???

usually you figure 15 amps max per circuit. How big is your hps? I roughly, to be safe, figure 1 amp per 100 watts. I know it is less than that.

It also depends what other things you have on that circuit. If you have your exhaust fan, fans, and other equipement on the same breaker then you might have to move things around or add new lines. Be very careful overloading things. ask all the questions you need to as this is far better than having a fire.

Peace

Agreed always be careful when plugging in stuff. With two 400w and misc fans, I think you should be under the 15 amp limit as jangel says. But keep an eye out. See how they do when you first plug them in. Remember that in your house many of the lines have multiple outlets (like the kitchen or living room will all be on one line). So although you may have the 15 amps covered fine with your grow equipment (depending on if the two 'rooms' are on the same line), you may also want to check out to see if anything else is on that line. For example: while I am way under the 15 amps for my grow line, An outlet in the room that hooks up to my laptop/printer is also on that line, so it must be taken into account. Make sure any other appliances that are on the same line are taken into account. We dont want you plugging in a TV or radio and blowing the fuse.

Also a personal side note: Make sure you know exactly what lines your power is on. I blew one once because my girlfriend plugged in her blow dryer and straightening stuff for her hair. BAH women with all their products! At least she looked good as I stormed into the room yelling.... ;-)

Now, if you look in the first My Little Grow Thread (the link is in my signature) you will see what we did for our now grow room. We brought in 3 new lines just for the grow room. This gives me 45 amps to use, with each part of the room and each plug on an individual breaker. This way we have enough power without fear on every plug. If you are not comfortable doing this, then make sure you get an electrician in to do this type of work.

Your life and your family is worth more than any plants. No matter what.
