How much power can I draw from one circuit

I was wondering how much current can be drawn from one circuit? I have lots of pumps, lights, transformers, and tons of other things plugged up to my system. Everything i am running is on the same circuit.....that's just how it was designed.: I have heard that you can pull 1800 watts per circuit before tripping the breaker. The reason I'm asking is because I was running my Haier Dryer yesterday when the Blackout occurred....the breaker tripped. Any suggestions for prevention? Any advise on how to deal with this?

 

here is a calculator that I use some times to help me figure out if Im using to much on one circuit. You will need to know what amp circuit you are on to be able to use correctly. copied this off a website I found. I hope it helps.

10A * 110V = 1100W and 80% safe usage is 880W
15A * 110V = 1650W and 80% safe usage is 1320W
25A * 110V = 2750W and 80% safe usage is 2200W
30A * 110V = 3300W and 80% safe usage is 2640W

Power Calculators for quick conversions.

 

In most households, if your using a 120 volt line, the breaker is usually 15 amps, but it can be higher or lower.

 

Yamaharider nailed it. You never want to load a circuit to the max or you are asking for trouble. 75 to 80% of the rated amps is the recommended load, most circuits are 15A so around 1300 watts per circuit.
I always split my load between circuits so if one trips I still have pumps circulating on another. I installed a dedicated 20A circuit just for my display but I still run a couple Koralias on a seperate circuit in case one or the other trips.

 

Yeah, I don't think the Koralia's or other simple pumps draw that much power. It's the Metal Halides that I'm concerned with combined with all the other stuff. I have 3 250W MH's and 4 54W T5's = 966W. I am borderline at best with all the extra's. My problem is that I have to go to the next room to hook up to another circuit. I may run a separate line under the house and feed it to a drop point in the Tank room so I can split it up a bit.

Thanks guys for your help.

 

It's always wise to split your equipment up between breakers if possible. I try to run my main pump on a circuit different from my circ pumps. That way if one of those breakers trip then you still have some circulation in the tank.

 

you could add another circuit breaker box just for your tank with two or four switches, I would be a pain to do it but would be pretty cool when its done. Just pull big wires so you can up the amps.
small boxes are like 30 bucks at home depot
