the 400w light is around 3.5 amps. the pumps and fans arent more than 2-3 amps total. The minimum size for a circuit is 15A. I think you will be fine on one circuit. Just dont plug a 3 way into a 3 way into a 3 way. Get a good quality strip plug to plug everything into


you cant "join" outlets but obviously you can run things on different outlets. But typically all outlets in the room will be on one circuit, so an extension cord to a different room would be needed.


What do you need wire for? Just plug everything into the strip plug

Great help.
what i meat by wire is that the box is build from scratch, with panel inside.
I needed to know the gauge of the main power wire that i could use; did not know if good power strip cord will be sufficient. You said my total is 15amps, power cords are 15amps too so i can use it.

once again
thanx for help
