I only have 1 outlet in my basement. Will this be enough to run 2 - 600 watt and a 4 foot 8 bulb VHO? Will I blow a circuit? The 2 600's are on apollo digital ballasts...
Should be fine, each 600w lamp will use 5amps and the vho I assume is a florescent so you should be good on the 15amps. You can only load a circuit to 80% of its max capacity with continuous loads due to high inrush current on startup so you'll be close but it should be fine, couldn't hurt to try cause you'll know quickly if it doesn't work.
