Thanks! And thanks for poking in! Welcome aboard. Great to have someone of your caliber along for the ride! I'm in the process of learning to upgrade my electricity. Still literally won't be half the size of your grow.
Hey Papa, and all. Awesome journal. I'm eating up all the electrical info - it's not an issue for me at the moment but my plans and dreams for the future include many more watts and amps so having some knowledge about what it takes to keep from - burning down the house - is much appreciated.
I'm also very pleased to see I'm not the only one around here who's having fun with Photoshop. Nice work brother grower!
You should know by now that size doesn't matter ;-P It's all about the quality brother.... And....you sure got that! Where do you think I am getting my ideas from? This site and other great growers like you that share their experiences. This is starting to sound good, I can tell that I am highly medicated right now. So, I better get to my thread and update before I forget.
papa,
been following on the electrical, i sure hope my hubby gets it, I DONT DO ELECTRIC... but he wants to know it, so showed him this...it is interesting tho, but I need electricity for idiots....
those plants are hugh....how big a room, and how much light?....all for now, lavendar, shakes head as she ponders what she has read....
Green007 Thank you for....

One of favorites of all this......well, actually any Talking Heads will do!
That's a good point... I'm big on wiring it right! No short cuts!
get it short I slay myself
Papa sometimes I miss wiring stuff, this helps...
Your wiring looks fine man no burning issues
Let's talk about legs... not those ones...
One leg of electric current varies from about 100 volts to 120 volts that is why some people say 110 volts some say 120 volts...
One leg -single phase 120 volts
two legs- 2 phase (What most of you all have coming into you house) 240 volts
three legs- 3 phase (What I have coming in) 480 volts
So if I say 220 instead of 240 or I could say 277... it's all the sort of the same JUST think oh 2 phase not about the hard numbers on voltage...
So the last place we left off was wire gauge size...
The wire carries the load, not the breakers simple right?
So the 14 gauge wire we all have in our houses will only take 25 amps before it heats up enough and trips the breaker or fuse... So when a breaker trips just think to yourself wow the wire in my wall on that circuit is 194*F
That's why it's a really bad idea to up you breaker size in any panel...
Papa you asked before is it OK to take out a 50 amp breaker in your sub panel "my AC only needs 30 amps" I would just leave it be, you might get a bigger AC... The wire looks to be #6 or #8 we wire hot water heaters, stoves,AC with it. That's why in your main panel the circuits look unbalanced... If you did change it you would not get amps added to any thing...
When you open a sub panel you will see 2 legs of 120 volts and one common or white wire you wont miss them they are big, hooked into a couple of blocks we call the blocks a "bus bar"
On a stove,ac,water heater circuit we use a breaker that snaps over BOTH legs of 120 volts. Or over 2 bus bars
On a 120 volt circuit we use a breaker that snaps over one leg of 120 volts. Or 1 bus bar
So the sub panel is just a distribution center for power, be it 120 volts or 240 volts depends on the breaker you use...
When running a sub panel we first think how far from the main? How big is the TOTAL loads going to be on the wire...
We will use my sub panel as a guide since we know the #1 thing you must know before you add on to any sub panel WIRE size It's 75 feet of #3 copper the wire itself not the sheathing or coating is almost a 1/4"
I have a 100 amp breaker in my main that run's my sub panel. In my sub panel I have 190 amps worth of breakers and circuits???
Hey how the hell can I do that? Simple I will show you how... It comes down to knowing your loads on each and every branch circuit coming out in the sub panel... So Papa's total real world TOTAL amp draw on his sub panel can only go to 50 amps based on the breaker and size of wire at the main the sparky put in...
More to come Got to go take care of the girls
.Hubby will do fine. At the pace we're gonna go - if one can't keep up, then its prolly wiser to get an electrician.
Yep I totally agree!
OK, read the few pages in Dr Who's journal. I gotta go back and read more of the journal. Good journal. But I did read all the stuff you've posted there. I'm jealous of your panel that's for sure.
I'm totally with you so far on the legs and 110/220.
Let me make sure we're on the same page. The run from the Distro to the Sub is a 60A prolly 6G wire. From the sub I have 30A allocated to the Air. Leaves 30A. I like where you're going with getting more out of it by knowing each drop.
Yep you have 30 amps left in that box! sorry I thought it was 50 amp breaker to the sub panel... And remember that ac only needs 30 amps on start up... So a person who is really on the ball can balance those loads or shut one down one temporally while the ac start's as not to "kick the breaker" going to the sub panel...
Are you thinking I will be able to switch to 220v at the Sub
Yes we can use that left over 30 amps on 120v or 220v at the sub panel we can switch back and forth hell you decide!
Or pull another 60-100A run from the Distro?
I will go back and look at your main BRB the only way we could do that is changing out your whole MAIN panel your full on breakers...
This is super helpful for me and lots of others! As I said, man - I plan to suck your brain!
Mule sure knows his stuff looking at the posts. I am lucky enough to have an electrician friend that helps me for just price of materials, he likes being in the room He ran me new 200amp service with 100amp on each leg and has it wired ready to go for 400amp. He said soon we will amp it out to even the load between leg A and leg B because he mentioned it will save on power as well. I wonder how exactly that works, but he said it did. I'll be checking posts for Mule, thanks for the info!

Mule - I'm probably too late, but hopefully I can save you some typing.
Let's first explore the 220 at the Sub. I'm fairly convinced that should solve my issues.
I will try to find the right page in Aberration's Journal, but I think we should try to copy lots of his electrical.
Edit:
If we can end up withsomething like this I think it'll be perfect!:
Good stuff! Are you sure you mean Amps, not Volts?
Perhaps we can get a better answer from Mule, but as I understand it, you want approximately the same load on both legs because its alternating current. Your meter ticks as it alternates. If you load up one leg, then it has to do more work in half the time. Where as if each time the current alternates it does work, then the bill is reduced. I rearranged the loads on my last box and I'm pretty sure that dropped the bill significantly.
Hehe. I was going to offer my amateur advice, but I see mule has it in hand and defer to his expertise. You know, the one thing I now realize I did badly on that wall panel was that all 4 120V outlets come off of one leg. I never heard about balancing them until just recently myself. Makes me want to rewire my main panel again to balance the likely loads. I just got done rewiring 3/4 of it a month ago. At least it passed inspection.
Your plants look good as always.

Speaking of the electric - how's this sound for some initial thoughts...
Basically I think a 30A 220 run about 18' from the Sub Panel up to the middle of the ceiling above. All the ballasts can go towards the middle and cords can reach that point. In the middle of the ceiling - one bank of 4-6x 220v on one timer and 2x 220v on another timer (Flower and Veg). There should also be 2-4x 120v at the same location.
Could be done with relay(s) or large timer(s). Whichever is cheaper and/or you think is better.
Sounds great we can do that!
As for the relays or timers I'm going to my mentors house to pick up 4 panels so I can take the apart color code them so I have some "dead teaching aids" in my sparky thread... I will ask him what he thinks. However I don't want to use products that would make it hard to find them if something failed timer,relay wise...
Papa changing out that capacitor reminds me how many of these we have in our grow rooms in lights and ac units...
Let's talk about stored energy and safety.
all capacitors have stored energy, they have a positive and negative side just like a battery. The labels or markings may not say + - but the are!
The purpose of a capacitor is to discharge 1000s of amp's of voltage into something like a AC unit motor to get the motor spinning, or a mag light ballast to get that plasma arc going to light the bulb...
With that said, it is the amp's that will kill you not the voltage in electricity. I could touch one leg of 66,000 volt's if it had one amp for a "draw" (better be wearing god like shoes) however a 120 volt circuit pulling the full 30 amp's is scary thing! It has the ability to "draw you in" It makes every muscle in your body freeze you cannot move! The bigger voltage it just bites ya and might toss you off a ladder or across a room...
So never ever touch any bare wire or connection on a capacitor. Some are metal and your holding the ground!
Now some people are thinking ah hell I did that and lived... You got lucky when you unhooked it, you discharged it, or it was truly dead.
It won't draw you in because it discharges in a split second with a ton of amp's...
Papa I'm on it bro! I will get back with you about the timer, relay thing Keep it green Papa!
