or a better question would be what are the fewest amps I could pull with a 1000 watt setup. This includes all power you need including fans ...
I am limited to 15 amps

u have a 7amp pull constant and on ignition goes to about 9amps on a 120circuit, on a 240 u have 3.6 draw with a surge to 5 aprx. remeber it is always wise to leave at least 2 amps on the circuit for power on surge so you dont pop the breaker. no lights no plants. if u have any question what is on the plug circuit get a lamp and find the panel check the plug with the breaker and anything else that is on that breaker and remove uneccassary items, should allow you to dedicate it .
Everyone's setup is a little different so we have no real way of knowing exactly what is best for you without more info. How many fans are you running? What is their power draw? Is it hydro with 1, 2, or 3 pumps going? Do you have a C02 monitor?
As a general rule you do not want to pull more than 80% of the lines rated current. So you wouldn't want to pull more than 12 Amps. The easiest way to figure out how many amps you are pulling is via a "Kill-A-Watt" which can be bought at your local hardware store or even possibly wally world for around $25. A less precise way is by the following calculation: Watts = Voltage x Amperage. This does not account for ballast or equipment start-ups.
So basically, your 1000w HPS will draw a little over 9 Amps of the 12 you should be using. That leaves about 360 watts for you to play with.
FYI: HPS ballast convert the voltage down to 110 volts. 1000/110 = 9.09 Amps constant
