Need a little help with electrical. How many 20amps do I need?

[pennyguy23]

I will have 4-400w MH 8-54w T5's.
4-400w ACLS units
Geo skimmer. Not sure on the watts w/ a panworld pump running it 45w
Hammerhead pump ?w
1/3 chiller 115v
4 6100's with Multi. 15w (each)

Thanks about what I can come up with now. Any suggestions

I run my 120 reef on two different 20 amp circuits. i would suggest two or more. if you want to figure out what you will need, you can use the formula: Amps= 120Volts/watts. if you use that equation for everything you have, you can figure out how many amps your tank will need to run. If you come up close to 20 I would always do another one in case of power surges and things just to make sure it didnt get cut off.
hope this helps!!

What does anyone else have.

I would run the lights on 1. Chiller on 1 and pumps on 1.. Let's see that's 3- 20 amp circuits. On my 500 gal I run 7 20 amp cicuits at 110 volts and 1 20 amp 220 volt for my chiller. The chiller should have seperate circuit.. And my personally I would run a back up chiller. I do, and have heard horror stories about chiller failure. So if your having power added think about extra circuit for the future...

Your own nuclear plant in the backyard helps also....

The Hammerhead pulls about 4 amps.

I'm running 3 - 20 amp circuits on my 400 G system.

2 X hammerhead pumps
1 X baraccuda pump
3 X sedra 9000 pumps
2 X 400W DE MH W/ light mover system
8 X 55W PC
2 X 500W heaters
1 X Iwakia 30
2 powerheads
various controllers and a ozone generator

I ran from my main power box (which is a also in my fish room) to a pony box. In there I have space for eight, and I currently use four.
