You have to find out the amp draw of your fans and use the same formula. KEEP IN MIND, most household outlets are 15amp, your getting close right now and your not even looking at the inrush current this is going to produce. Inrush current is when you first fire the shit up. So if your 400w lamp is 3.3 amp, the inrush current is close to 33AMP! Fire your lights up at different times for sure!
Just with the lamps your already at 9.6 amp continuous, I'd consider splitting your lamps on different circuits with your fans divided or going to 220V.
good info thx Psycho4Bud!

would spliting the oulets same room different wall would this help or are they same circuit? 5 yr old house only a celling fan running.
think can run off outlet in attic, 25ft run tho..... love how this gets you thinkin..

will not power them up at same time ever. during flower the mh is only going to be on 3 hours maybe less and maybe not soo much.

looked on one fan did not see data? all 5 little desk fans.. also two 6 inch computer type fans inside light hood. all move some air tho.

does the timer need to be heavy duty? just going to handle lights and run in attic when ran. fans and filter will run 24 hrs.
