Electrical Sub-panel Question?

[jacob30]

I am wiring my equipment room and I am installing a sub panel to support 4 -20 amp circuits. The sub-panel has six slots and is a 100 amp capable sub-panel. My main panel is a 200 am panel. My question is what size feeder circuit breaker will I need??

Of course this depends on my equipment:

2 CL reeflo darts
Iwaki pump return
2 250 watt MH
1 400 watt MH
some T-5 actinics
Deltec skimmer
Heaters (500 watt)
cal reactor
air conditioner 15000 btu
maybe a 1 hp chiller
fans x 3
UV sterilizer 40 watt
aquacontroller III
a few maxi jet 1200's
Frag grow out light 1- 250 watt


That should be about it. Any advice from the electrical savy would be appreciated.

Thanks

Jacob

If there is no main breaker I would put in a 60 amp breaker to feed the sub panel. You could use a 100 amp breaker and #2 wire if you like but I doubt you will use more than 60 amps.

I would personally use 6/3 w/Grd Romex (copper) and a 2 pole 60 Amp breaker to feed it. You could go bigger, if you wanted to. I doubt you would ever come close to using it at it's full capasity.

BTW, if this is going in your fish room, G.E. makes a nice Rain-tite plastic circuit breaker panel that holds 12 circuit breakers. I think they run about $25.

Sounds like the 60 amp is the way to go. Thanks for the input Fast Fred and Paul b.
