relocating oven circuit...

hello everybody,

I want some of the electrical geniuses to double check my plans. I am moving into a nice place and I want to setup a 4k bedroom flower room. I was planning on utilizing the oven circuit for powering the light control box. I assuming its a 40-50amp 240v circuit.

I was thinking I would turn off the oven breaker, double check that theres no voltage at plug with my multimeter, then get into the attic and chop the romex cable near the kitchen attic area. then get a metal junction box from home depot and 20' of more romex cable and run it into the bedroom through the ceiling in the closet and over to the control box mounted on the wall.

does any electrician forsee any problems or concerns in doing this? I figure if i run just 20 amps of lights on a 40-50 amp circuit I should be A-ok


my plans seem simple enough, I just want to make sure what Im doing is safe

edit* i will figure out what guage romex cable is already in use for the oven, and just get more of that, even though im only pulling half the available amperage

I will first give you think link to read through, http://www.simplyhydro.com/growth_chambers.htm.

Splicing into existing wire without junction boxes is asking for a fire hazard. A 220V circuit is only 30 amps I believe, and a 1000W uses 5 amps @ 220V. I would first check the breaker size supplying that 220V outlet, also keep in mind.

"You must note that for safety, the Canadian Electrical Code states that you can only load circuits up to 80% of their recommended capability."

normally ovens have a 40a circuit i believe. water heaters use 30a. he can get 50a at 220 or 240v easily.

He needs to know for sure, so he should check the breaker.

80% of load on a 40A circuit is 32A.
80% of load on a 50A circuit is 40A.

You need to know if you have 8 more available amps to use.

indica dom, i dont think you understand me completely. I will not be using the oven, I will be taking the large guage cable feeding it and re locate its final position from near the oven to a different bedroom by splicing it with a junction box in the attic. Im pretty sure thats the safest way possible to extend the circuit.

all electric ranges use a dedicated 40 or 50 amp circuit at 240v, if i plan on doing a 4k grow i need space for 20 amps. so I will be pulling half of the allowable amperage through the circuit, staying way under 80%

I figured this would be a pretty popular way to wire a grow room all things considered, has nobody heard of this before?

I understand exactly what you are saying...who the hell said you would be using the oven? I sure as hell didn't...

This is a fire hazard.

OR, which is it, 40A or 50A?

This is why I asked you if you will only be running lights off of that breaker for your oven. Lots of people have tied into the larger circuits in their homes to run more lights, most people however don't know shit about electricity and will end up setting a fire, or getting arrested.

@nonuggets, If i utilize the circuit already in place in the panel i will not have to add any breakers or mess with the panel in any way. I think thats easier then trying to add another circuit, and since its a rental house, when the time comes to move, I will just go into the attic and disconnect the added junction box cable and reconnect the original cut off cable going into the oven outlet, with no visible changes to anything except a small patched hole in the bedroom closet where the cable fed through.

Um no, what he is saying is why don't you just keep your oven right where it is, add a breaker, and run a cable from your breaker box through the attic, and into your grow room? That would be easier and safer than what you are trying to do.

indica dom, the circuit breaker will be visible for me to look at after I move in, then I will know exactly the size/brand of breaker for that circuit. as of right now I only know its an electric oven which operates at 240v and is controlled by a large 40 amp or 50 amp breaker.


why do you feel a junction box (which is made to splice high amperage wires in a contained/grounded metal housing) is a fire hazard?

OP if you disagree with IndicaDom then you are wrong because he can never be wrong apparantly and the rest of us are retards, and if he is wrong then it is your fault for not understanding what he was actually meaning because he was right all along you just didn't understand him because you are inferior to him.
He won't answer your question he will change it to suit an answer he has and then go on and on about it is THE BEST WAY no questions asked

Why splice the wire at all? You have open slots on the breaker box for this very reason, add a breaker, and run a clean wire from the breaker box to your grow. Not sure why you think your method is easier, when I will be able to run a clean wire through the attic and easily attach some housing at the end of the wire into the grow room? It is a fire hazard because you are not an electrician and you are trying to install a junction box after splicing into a high voltage line, when you could easily add a breaker and run fresh wire.

You are butt hurt that I proved you wrong, get over it.

lol, thank you gaztron, I was starting to think the same thing

You asked for advice from someone with electrical knowledge, then tried to challenge that knowledge with your lack of knowledge. Sorry your ego got hurt, but the way you're doing it is wrong and unsafe.

if there is no slack in the oven line, then you will need 2 junction boxes and a piece of cable in between the 2 boxes. dont mix aluminum and copper wires (without the proper wire nuts) so stick with whatever is already being used for wire.

dont forget the big blue wire nuts for your connections, the connectors for the wire, and the blank cover for the box. if your going to try and fit 3 cables in 1 box, get at least a 4 11/16" box. dont forget to ground the box if its metal.

then run the same size cable to the grow room and install a small sub-panel. then run your #12 awg wire for your outlets off of 20 amp breakers.

you dont put #8 awg cu wire onto 15 or 20 amp outlets protected by a 40 or 50 amp breaker.


i would run seperate homeruns from the main panel or a subfeeder from the main panel and not use the oven line but if it works for you then great.

LOL you don't have electrical knowledge, you're just pulling things from literature again.
And in regards to proving me wrong, you proved nothing because I was only talking about your bitchyness and you continued to bitch so...........

indicadom, please leave my thread.

adding another large amperage circuit would be putting the panel over its regulated 100 amp service, that would be a fire hazard. at the very least it could be a problem if someone decided to stark cooking or doing laundrey during my light on cycle. I feel using an existing high amperage circuit would be just fine, if not preferred.

I dont know why i even post threads, all the really helpful people left this site years ago.

thank you, another rollitup veteran. I will be using hardwired light control box and running everything else off the rooms 120v circuits

cheers

it doesnt matter what size sub panel you add isnt going to overload the main panel unless you are using that much load.

for example if your grow room is running 5000 watts total, it doesnt matter if you add a 30 amp subfeed or a 100 amp subfeed. your still only going to use 5000 watts.
