So I'm growing at my friends place and thinking about adding a 1000w switchable system to my 400w switchable system, but they'd all be in the same room. 400w would be in the closet, 1000w system would be outside of it. I'm worried about this tho, since I've heard having over 1500 watts on a circuit can blow it out/cause a fire. And since we have multiple fans going in there as well, I wouldnt be surprised if we went over that limit when I add the 1000w system. My question is - is this safe? I have no idea how much the room could handle electrically and I'm not electrician so I know next to nothing about any of this. I just learned about this through looking up hps safety hazards. if i have the 1000w and the 400w on different outlets will that fix the problem? I'm really just kind of sketched by this since I have this 1000w system and that's the only place I can grow other than a closet in my house which I'd have to cut holes for and if it were to be in my closet (2x4) the 1000w's full potential definitely wouldn't be maximized. Anyway, am I wrong and will the lights be fine? Or should I reconsider this setup given that it is electrically unsafe?
