15 amps?

I AM A LISCENSED JOURNEYMAN ELECTRICIAN. THE ANSWER IS HELL NO! Ohm's Law states that Power(Watts)=I(Amperage) X E(Voltage). So, 1K watts on a 120V ckt is pulling about 8.3 Amps roughly. You add in an AC unit, and you are just asking for a fire. More than likely your 15A breaker would trip first, but there's no guarentee. Dont push your luck. Either research how to sun a dedicated ckt for the AC unit, or hire an electrician to put it in... And just because you have a 15 Amp breaker, does not mean that you can load it all the way up to 15 Amps... The rule of thumb is 80%... So, 80% of 15 Amps is 12 Amps... Anything past that and you are literally playing with fire...

he states he is only gonna run the fan on the ac and not the compressor which would be fine, even though he is giving himself the potential to overload with the flip of a switch on the ac which is not ok

Whatevz... I always have separate ckts for lights and other equipment. Still sounds sketchy to me still... I mean, how hard would it be to just drop a new ckt and rest assured you'll always be fine, no matter what... It's not the healthiest thing for ballasts to haveta share loads with other things either... Could end up shortening the life of the 1K ballast, and or components like capacitor, and/or ignitor(if itz a HPS)... Us wiremen are a usually a lil' more picky, with as many burn-outs as we've seen and re-wired, properly... Just sayin'...

Yup, most Important thing is to make this a sensible debate and share knowledge rather than turn it into an argument as many of these forum posts seem to end up being. Better to be friendly than blow ourselves up.
I'm no sparky but know some basics.
I'm fortunate to live in an area that doesn't require a/c but would imagine that would add another variable with the compressor.
However, I stand by what I said about start-up draw tripping breakers and ust pulled out the old ballast to check it out. It's a Powerplant Daylite 600w and was running with a 250w veg on same circuit, a 6" ruck fan and a 2kw heater and used to trip the 13A breakers at lights on until I put more timers in and spread the start-up load.

If your 1000 watt is pulling over 9 amps something isn't right, it should be in the 8 amp range, I would suggest running a small fan and get rid of the AC unit as it would use more power then a regular fan would and less ampage.

Wow I give up! As long as everyone on here knows a guy that knows a "qualified electrician" than you must be good.
No need for advice from a Licensed Electrician with 14 years of experience that does this for a living everyday.
Instead I'll let everyone take advice from the guys that live in there mommy's house growing plants and that don't have jobs so they have plenty of time to answer everyones questions with there vast knowledge that they have obtained from someone they knew that had a job.
Now do ya see why I didn't go down that road?:wall::wall::wall:

The only reason I have the a.c. unit in the wall is to pull cool air from the basement into the tent, it will only be temporary until I find a in wall osolating fan or get to the hydro store to get a small inline fan, so far there has been no trips of the circuit, I have also been inspecting the wiring on the ballast light a.c. and the wall plug they are not getting hot and no signs of wires burning I think I should be fine for now I was also thinking of switch the 15amp to a 20amp

20 amp would be the way to go as long as your wire is 12guage and it wouldnt be a bad idea to use a 20amp recep also. DO NOT install a 20 amp brkr if you only have 14guage wire.

Journeyman huh. well sry bro this statement of yours shows very little experience. The fact of having other items on the same circuit as a ballast will not be unhealthy or shorten the life of the ballast in anyway. lol It did get a laugh outta me though. The thing that would possibly cause the ballast's life to be affected would be a voltage drop, which you will not get from maxing out a little 15amp circuit.
Your a long way from getting your masters, my guess is your prob a lineman if a journeyman at all. You and the nob below you do not need to be trying to correct my statements if you are nowhere near qualified let alone on my level of experience.

Oh come on guys, Let's not turn this into a slanging match. Play nice please. We are all here with the same aim.

I think I am go 240 to outside my tent and run most of the tent with that and have the 15amp still as a backup
