Wiring help

[citygrower]

Hello everybody

I needing to upgrade some wiring in my house to upgrade to a 1000w light. Currently I have maxed out the circuit I'm currently on.

I would like to run a new breaker 30amps which i would like to run to 2 receptacle. 15 amps to each receptacle. Which should give me plenty of power for my whole room.

My question is should i run 2 wires of 10g romex from the breaker or it is safe with 1 wire running to both receptacles?

I was planing on using romex 10/3 wiring.

Thanks in advance
Much love

You will wat to move this to grow room design and equipment forums to have a sparky there to help you..

IM no electrician but imo you may be overkilling but dont know what
your room draws.

As a rule of thumb you dont want to draw more then 75-80 % of effective load on circuit.

I have a 1K which I run on a a dedicated 15 amp line ( 1K draws 10 amps, 75% of 15 amp max) using 14/2 romex.

Then I have another line which is 20 amps with 12/2 romex.
This runs the exhaust ( 3-4 amps give or take) a space heater
in winter ( 5-6 amps give or take) and miscellaneous fans,
an auxillary outlet ( for cleaning or whatever) and that pretty
much takes care of it.

If you are running hydro with pumps etc. ( I dont) then you will
need to add the amps of what they draw up and figure it out
yourself.

You will probably need to provide more info on what your setup
is and draws but from what I see right now you may be a little
overkill on the 30 amp... Also dont know how many open slots
you have in your panel.

Btw.. the bigger gauge wire i.e 10/3 the more pain in the ass is
it is to work with. Also just because you run 30 amp capacity
with approp. wire doesnt mean you can use 15 amp receptacles.

You will need to use 30 amp outlets and receptacles to be code
and they can get expensive and a PIA..

If you have room in your box just run your 1k off a dedicated 15 amp 14/2 line.
That takes care of the meat and you can figure out what else you need for the gravy

I might be going a little over kill.

To be honest i been reading lot about wire safety and i have completely scarred the fuck out of myself.

I currently have 1 400w & 1 600w running in my veg area but i need to get my flower area going. So I'm adding a 1000w light. it pulls 9.4amps so total i think I'm would be around 20amps i figured 10amps would be plenty of extra for 2 or 3 fans.

For receptacles i was wanting to use standard 15 amp receptacles but use 2 giving me 4 total plugs.

Thanks for the help man.

Also if a mod could move this to the right area i would be extremely apperceive.

maybe running 2 15 amp breakers would be easier?

I only have to run about 20 feet of cable and its fairly easy from where the box and room are located.

There are a few ways to do this...personally I would give your room its own subpanel.. Providing you have room in your main. And you own or will be living there for a long time. I wouldn't think you need more than a 60amp 2 pole breaker in the main. Run 6awg to your sub panel from main (put it next to main to save on wire cost. Then run your new wiring to that and you will be golden. Also easier to isolate your grow. Don't forget to turn off your main panel before installing the breaker...I did that once.....once

The first thing that you need to understand when doing electrical design is that the circuit breaker HAS to be/match the lightest-rated component in the circuit. If you were to use a 30 amp breaker, then all 30 amps could be applied to just one of your 15 amp receptacles even though there are several hooked to the circuit. Good things would not follow.

Your second idea about using (2) 15a breakers is the correct way to go about it. This provides the correct protection for the downstream components, with commonly used plug configurations.

If you are up for a little more work, the sub-panel idea that Phat presented gives you the most flexibility for future expansion and change. You can also have more numerous dedicated circuits, provide individualized protection to certain types of components, have better protection, etc, etc.

If you need a little more info on installing a sub panel u can always shoot me a pm and I will Rey to give you a step thru...watch some YouTube bids on it to give you a rough idea of what you want...

Thanks for the feed back guys!!
I truly appreciate it. This stuff has been stressing me out hardcore.

I don't have the option of running a sub panel but i do have a few open spots in my box.

So 2 15amp beakers with romex 10/3 wire would be fine right?

How this look for a parts list?

Or should i maybe just go ahead and run 20amp? I would not cost much more...

Also I'm having a buddy help me with the wiring but i told him i would take the time to learn what i could so I'm not just having him do it for me.

As soon as I get home I will give this a good read and give you a step by step guide from install to finish. Landing the wires in the panel is the hardest part of residential electrical so if you can do that you'll be rewiring balasts in no time

#10 wire is way overkill for a 15a circuit, and will make terminating the receptacle difficult. Unless your a very long distance from the panel, #14 is good for 15a and #12 for 20a. I prefer to run a minimum of #12, but it is more than required.

Good stuff. It's only like 20 feet so ill run 12g wire.

Do they make wire with more then 1 set of wires running in it? Like 1 wire set that contains enough wires to run 2 breakers/2 receptacles.
Or
Is it easier/cheaper to just run 2 sets of wire?

There are multi-conductor cables available, but once you get past three wires (not counting the ground) they are hard to find. It used to be pretty common to share the neutral between two 120v circuits so that you could use, say 12/3 w/ ground, for two 120v circuits, but I wouldn't recommend doing it that way. Two sets of wire is your best option, I think.

You might want to spend some time checking out the following thread - there is a ton of information in there.....

Unfortunately shared neutrals are pretty common especially in commercial electrical. Saving $ on copper... Personally I won't do it its hack work...if this is going to be permanent use 12/3 Romex or armored cable of some type and run it thru the ceiling rafters and make it look neat...since there is water aplenty in the environment look into throwing 2 gfci 20 amp breakers.... If its a temp setup get yourself 10/3 armored cable and make it long so you won't need any changes in the new spot. I will hop on after I unwind from work and have a key board

Just run a new 15a circuit to ur 1000w light ull be ok running 8.3a on each line but be carefull when adding stuff cuz 12a is ur max play u have on ur lines.overload on a 1000w light could be dangerous!GL
