running electricity to a shed?

[PharmaCan]

You need to look at what gauge wire the past owners wired the hps with. It will do you no good if they used 14/2 and you add 12/2 to that. You need to figure out the amp requirements of your pumps and fans which should be listed somewhere on the equipment or in the manuals, and add that to the 400 watt hid. a 400 watt hid at 110-120 volts will take up about 3.3-3.6 amps. You must take into consideration that a 15 amp breaker has about 13 amps available and a 20 amp circuit has 16-17 amps before they will trip. Another thing to consider is the length of the run from the house. The longer the run the greater the voltage drop. Running equipment with not enough voltage is not only inefficient and damages equipment but is also a fire hazard so BE CAREFUL.

A great book to get is Wiring simplified by H.P. Richter and Schwan it'll answer a lot of your questions.

LOL - Obviously you are new to this forum, so let me explain to you how this works. Some users post electrical questions because they really want to do things right. (You can easily identify these posters because when an electrician asks them a couple simple questions, like, "What is the existing wire size?" they answer the questions.) Then there are the posters who just wait for a couple idiots who know absolutely nothing about electrical work to come along and agree with them. They don't really have any interest in doing things right, only in getting some degree of consensus with their hair-brained ideas.

It is a complete waste of time trying to educate/help this latter group.

The best thing to do then is to kick back and enjoy the comic relief.

Otherwise, pretty soon you feel like

Damn, you really have yourself up on a pedestal for only being here for 8 months.

ROFLMAO - Nah - It's more like 35+ years of pulling wire that makes me feel that way.

But, if you find fault in what I say, feel free to prove me wrong. In any event, lecturing the OP does no good, I've tried before and there's a certain type of person that asks for advice but doesn't want to listen. If, perhaps, I can open his eyes by approaching the situation in this manner, and the end result is a safer installation with more functionality, then the whole world is just a tiny bit better.

I hope you have a wonderful day!!!

I just want all the DIY electricians to be safe. I would hate to see headlines "Marijuana grower kills self while wiring grow-house"

You hit the nail on the head! And that's the reason for my sarcasm and pontificating. It's really just trying to open the OP's eyes in hopes he'll ultimately do things right and have a safe installation.

technically i should not have a shed on premises,

aaaaan you feel its safe to grow MJ there...

MAn, this isnt MJ specific info,,,I dont know why you dont research on a electrical site or books?

LOL you spend too much time in the outdoor forum

These type of questions are asked all the time here

You get things worked out on the purchase?



I got to laugh at Pharmacan, you are too funny. You are right, but funny

i just wanted to say that i wasn't actually going to mess around in my fuse box without help. i m just trying to prep it all up to that point. and about my shed,it cant be seen from any angle in my yard,6ft privacy fence. and im real friendly with my neighbors.
any way this is what i have done,i bought 12/2 outdoor wire, ran 70ft of wire & conduit to shed hooked up 4 outlets. also ran a water line to a utility sink.used the preexisting wires to hook up an outdoor light to outside of shed.

 

[TropicThunder]

Im not sure of the exact logistics of your setup but you may need to run a ground to the water pipe. The outlets should be GFCI also.

 

[jimmie]

ground what to what? its a pvc water line,its grounded at the main supply does it still matter about ground?

 

[TropicThunder]

If it is PVC you souldn't need to run a ground to it, just make sure your outlets are GFCI.

 

[ninfan77]

ROFL, ground electrical to a water pipe? Don't give the man even more bad advice !

It's not bad advice ninfan77. Depending on the setup running electricity to a detached structure may require a ground be run to metal piping between the two structures, including water pipes. In his case it's PVC so it doesn't really matter.
