First Time Poster Looking for a electrician for help with Load center Diagram!!!

Aren't u going to put in a new breaker? If so then u would mount it to the line in the empty space on the bottom right.

but the room has a heater in it and someone threw out the idea of running the main line off that wiring and breaker and since its already there hook my load center up to that, but thats why i was asking about mabye replacing the breaker for a stronger one.

I would not recommend tapping off of the heater. By putting in a larger breaker you negate its inherit safety.

Safest way, run a proper cord from main load center with a two pole breaker to make a second breaker box in the room of your choice and then you can use your original diagram with numerous 220 and 110 runs with associated current trips.

Well that was the intended idea but im also trying to make this cost effective but i dont wanna sacrifice saftey over money

I'm not sure exactly what everyone said but DONT PIGTAIL; DONT BURN YOUR HOUSE DOWN THEN GET LOCKED UP or pay big fines!

3 600 watt lights is 1800 watts / 240 volts = 7.5 amps. 8 Gauge can handle max about 10000 watts for ~5' length That's 40 amps. 8 will work if you use ~60% of that 10000 if your line length from the main panel is 20+ feet. That's 24 amps.

You need to remove 2 single pole breakers and put in a single slot 115v double breaker with two outputs. Then you will have room for a 35 amp 240volt breaker for the feed to your new panel.

a 20 amp circuit will be pretty much maxed out, if not on the verge of overload, running 3-600 watt lights. It needs to be at least 25 amps.....

thats a 20 amp 220 circuit, so 3 600 watt light will draw about 10 amps

... found a single 220 plug with grey 3 wire romex coming out the back of it if this is the same type of wiring that my heater is running off of can i just go buy a 5-6ft piece or romex and wire that plug so my load center plugs into that ill post some pics or the wires on the heater and the plug in question

romex or you can also buy extension cord by the foot at most home depot type stores.
you can use the existing wire IF it has 3 wires plus a ground. a 220 heater doesn't need a neutral so it may have been run w/ 12/2 wire and not have a neutral.(blk to 1 side of breaker & white to the other. if that is the case,you will need to run a new wire back to the panelbox. if you are lucky, they ran a 12/3 romex so you have a red and a blk tied to the breaker,a white tied to neutral(and a ground). then you can use the existing wire but you can't use a bigger breaker than what the wire is rated for.if the existing wire is 12gauge, a 20 amp breaker is the biggest you can use.10 gauge wire can handle 30 amps.most electricians will use the cheapest wire they can so the odds of someone running 10/3 when they could get away w/ 12/2 is very slim. hopefully you have 12/3 wire so you can do your load center like described in your 1st post. if its only 12/2, you could use it if your lights can be wired for 220 & you want to go that route.

can you post some links to the breakers you are talking about so i can have a visual reference

yeah my luck isnt that good madcow ha ha ha. well the only issue with running a new line is that the main load center is on the opposite side of the house so i would almost have to either run the line threw the house or up and over or under and i would rather not have a live electrical wire running threw my house so is the up and over or under a possiblity?

do you have a crawl space under? it would be easier. outdoors needs special wire & will look like hell.
what wire goes to the heater?

i believe is 3 wires black red and white and yes there is a crawlspace under the house

Also i wanna say while i was trying to look this matter up i found very few useful sites and discussions about this i may not have been looking in the right places but i spent alot of time on this matter and really appreciate everyones feed back

OK so ASSUMING the heater wire is 12 gauge,you can have 40 amps of 110 availible near your room.(+ whatever is already in the room) the 3 600 watt ballasts will use 1/2 leaving 20 amps for fans,pumps, ect, this might be enough to add 1 more 600 light in the future but if you expect to add more latter, it might be worth running a 10/3 or bigger for a subpanel.
I would not run all the lights on 1 timer unless you wired them 220 because when a light first fires up, the draw will be double or better for a few seconds & 3 lights will draw close to 18 amps. better to split them between the 2 circuits & balance the load w/ your pumps & fans.

240v/110 single/110 dual

12 gauge can only do 5000 watts; And that is pushing it really really bad.

Use 8 gauge bro

I will get the wires out of the heater and take a few pics and you can make an assessment from there i think the heater idea would be good but then again i agree that running a whole new wire would be better im just not sure how it would work i have some things to think about ill get back to you guys in a day or so thanks

so im looking at plugs for my load center that my ballast will be plugging into im wondering if http://www.hydroponics.net/i/135329 are usable or do i need http://www.hydroponics.net/i/132744? I only need 2 outlets currently but may purchase 2 so i have a total of 4 outlets. I am wondering though i know i can wire the 120 plugs to run 240 but is that ok or will they heat up and melt down keep in mind these will be running for 12 hour. I dont mind buying the 240 ones if it cant be done the other way but i didnt know and thought i would ask any ideas? PS im still workin on getting pics of the heater

http://www.hydroponics.net/images-hf/134150.jpg

those are 240v outlets.

dude don't get cheap here; its safer to get 240 rated outlets than put in 115 and risk a short circuit.

ok duely noted thank you i was thinking of going with the 240 outlets i dont mind paying for a them its just i have seen alot of the 120 outlets on the "name brand" boxes and wasnt sure thanks for the input foxnews lol

agreed. go w/ the proper outlets. you could wire a 110 outlet for 220 but all it takes is 1 stoner moment to try to plug a fan into the outlet......

Naw im pretty careful in the garden
