Yes you can.
Regular house is normally 14guage for 15amps, 12guage for 20, 10 for 30.

PS. Here is my disclaimer/warning I know this is correct however I'm not a electrician.

You are allowed 20 amp breakers, you would just need a 20 amp recepticle. You can tell a 20amp apart from a 15 amp by looking at it and noticing one of the slots is in the shape of a "-|"

Don't forget you have to have wire rated for 20amp between the breaker and the receptacle also.

If you are going to run a new circuit (ie new wire from the breaker box) run wire rated for 40 amp to a subpannel close to your tank. then install three 15 amp breakers in the subpannel and run each one to a couple of outlets.

A chiller doesn't need to be on its own breaker but if you got the room go for it. just make sure when you load up plugs you stay under 1500 watts on each 15 amp breaker ( I shoot for 1200 to 1300 on each breaker myself) or go by amps and put a max of 12 amps on each 15 amp breaker. this gives you room on the breakers.

you chiller is 5 amps so you could run it on the same circuit as a few pumps and such. Put the lights on another ect..

ok cool, thanks everyone.. glad my electrition is a fireman! :biggrin:

Yes of course, I neglected to mention that. If you want to use a 20Amp breaker you would need 12 gauge wire, and a 20Amp receptacle. Then if you want to plug your equipment into that receptacle you will also need to change the plugs to 20amp plugs. :biggrin:
