anyone?

its rated at 22A will that be enough for my 400W HPS?

22a is more than enough to run 400w, watts = volts x amps, so a 110v circuit would draw 3.6a, and 220v 1.8. Even considering the spike when you turn on the light, you are well within the units capabilities.

i've done a full grow and autoflower with 250 and am on my third grow with a 400 and hasn't let me down yet
