Enough Amps for new Set-up?

[Entacmaea]

Hi all, I am setting up a new 70gallon, and am wondering if one dedicated 25 amp circuit will be enough for the whole set-up. I will have 2x250watt MH lighting plus actinics, plus the various pumps for pretty high water movement, no chiller I hope.

Thanks!
Peter

Peter, a 25A circuit will be more then plenty for a 70G with two 250W and other misc lighting and pumps. A standard 15A would actually suffice.

If it were me I'd put it on 2 circuits for redundancy just in case something blows you don't lose the whole tank. Have pumps and lights on both circuits.

I run my 125 on a 15 amp line.

I'd do what davidmorh said. That redundancy is nice. Though Len is probably correct, that you could get away with a single 15A circuit.

My 20 with a 150 halide is on the same circuit as my bedroom and the living room. No problems.

You could always add up the wattage of all the equipment you plan on using, and do the math

watts=Volts (120) * amps

or

watts / volts (120) = amps

250 + 250 /120= 4.16 amps for your lights. (but remembe they draw more power when they first come on. so figure around 5.5 - 6 just to be safe)

Thanks everyone, looks like I should be fine. Thanks for the calculation help as well Bingo.
