In rush vs running current. Think abot it like a car. you use a lot more gas to go 1/2 mile from a red light then 1/2 mile while running at 50mph.
The turn on can take a lot of instant current. Have you seen fast blow and slow blow fuses? The slow blow are there for items that need a little extra humph to start up.
A resistive load would be say a standard light bulb. Just a thin wire in, all honesty, a short.
An inductive load is more like a motor where you need to create a magnetic field and induct that energy into another coil.
A HPS/MH ballast/light can be a merger of the two, but most likely are seen by the house wiring as inductive.
Oh Damn!!! 2 150W HPS and a few other items? Don't sweat it, roll.
I have the same set up on a standard outlet with *zero* probs.
(I've even grabbed single conductor wires to see if they are getting warm. Nice and cool) I don't think you are pulling that much.
Think about it, the 2 150's are pulling about 330W. The fan? 40-80W. You can plug in a 1500W hair drier no prob, can't ya?
im sorry..i just cant take electrical advice from someone who is on another thread asking electrical questions...sorry but my common sense wont allow it....
ive locked down the circuit i want to use...like i said...i will ony be pulling about 11-12a....im building a small closet grow running 2 150w hps...1 s&p 150 rated at 290cfm. and a couple small fans.....i just want to have a little leg room for adding if i need to
please explain rush-v- current and inductive -v- restrictive.
thats what im saying....i have a 15a breaker that has 12-2 yellow insulated wiring running to it...so running 20a from 12g should be ok....no
