Hi
A UK grower here, I purchased this room thermostat which i believe will switch on my extractor fan at a pre set temp. http://www.honeywell.com.pl/pdf/automatyka_domow/termostaty/T6360.pdf

Could you confirm the the wiring connections for me.

i think i need to wire my plug wire into term 1 (brown/live) and my plug (n) into term 2. I think i need to connect my extractor fan wires to term 2 for the (n) and term 4 for the live.

thanks in advance

PS i just found a link to someone else's project, but they appear to wiring it different to me! http://www.uk420.com/boards/index.php?act=attach&type=post&id=191615

Hey mate, I have a question.

Is it safe to run a 15' 12g extension chord to a single power bar, running 3 digital timers(all rated 15a); one for exhaust, one for circulation fan and one for light a 600w HPS? The power bar is rated for 15a, 1860w, very beefy all from one plug outlet. All together the amps are around 8, not much else running off the whole circuit. Maybe 2 amps tops.

Cheers!

How about 18awg lamp cord between 400w hps ballast and mogul socket?
I have some 18awg lamp cord laying around the house and i wonder if it would be kosher to put some distance between the ballast and bulb with this wire..?

Question moving into a room set up for growing. All sockets are 110 (presumably off different phases) so if I pull 110 out of 2 different sockets (got 10 plenty to spare.lol) that is out of phase and hook it to a 20amp 220v breaker (in the back where it would usually snap to the panel) then wire a 220 outlet off of this breaker will this be safe.

schematic 110 breaker phase 1 >>wires to room> One double pole 220 breaker > 220 Volt outlet
110 breaker phase 2 >> wires to room> ^^^

My thinking is being the 220 volt double pole breaker will flip in case of a short and there will only be power to the breaker and no electrical risks present.

Sounds fishy to me. Plus you will need to check to see if they actually are on different phases. Why the desire for 220?

Can someone help me with my connection problem? I am trying to hook up my ballast to my light socket...but I'm assured I've got every connection properly connected, except one thing.. there's a green wire on both the power cord and socket... and I've found no instructions that point that I should connect these two together...soo electrician experts, do I connect these two??

Could anyone provide advice for wiring a C.A.P. MLC to a 3 prong dryer cord? CAP sells the cords but does not explain what to do; the problem is the 3 wire cord doesn't have a ground wire but has a neutral wire. CAP only explains what to do with 2 hots and a ground. Would it be safe to hook the neutral to the ground lug and call it a day? Here are the instructions>> PDF Thanks for any advice!

Can anyone help me? I contacted CAP and they didn't respond. I would really like to make sure I have this unit wired correctly. Thanks.

so here is my electrical panel...only took me about an hour and a half...of course, i'm an electrician, it will take a layman a lot longer...the box on the left is an intermatic 40amp 120v timer feeding 2 20amp receptacles...im going to replace one receptacle on each circuit with a GFI since so much water is used in a growroom.

ok, mrly, here is a material list for my electrical station...

1 100amp Square D QO Indoor panel with added ground bar (use whatever panel make you like, rated to at least 50amps)

1 Intermatice 40amp single pole single throw mechanical timer

2 20amp single pole breakers (you will want 1 20a and 1 30a)

12ft. 12/2 romex cable (you will also want 3ft. 10/2 romex)

16 1/2" romex connectors

6 handy boxes

6 20a/125v duplex receptacles (recommend 3 be GFI)

receptacle covers

2'x2'x3/4" plywood

screws to anchor it all and 1/2" staples for the romex

Hi all,

My new attic grow is starting to flip the breaker..It just recently began as I had to buy a small electric heater for $20 @ lowes, to keep the space at around 70-80 degrees. Before adding the electric heater, I had 2 400 hps bulbs, running from a sunstream reflector hood, and 2 400w lumatek ballasts. I have one of the ballasts running on an extension cord 13amp, I think is the gauge. and then into the surge protector/timer. The surge protector is then plugged into a normal wall 110v. The other ballast is plugged directly into the other wall outlet. Is there a way to put a higher fuse in the breaker box, or any other sorts of recommendations? Have no real knowledge regarding electrical issues, but am concerned with intermittent breaker flipping..It's on right now, with one of the ballasts unplugged, and just one light on, but need to get this remedied obviously as cuttings, and seedlings grow and need the room. Are there any concerns to small electric heaters in grow rooms, ie, soil particles igniting? God forbid...The house is brand new :)

Hey bricktown how are ya!

I have just completed my GR construction, all equipment in place. 5 110v standard GFI outlets (in series or looped to one single 20 amp breaker) Breaker box is outside 30 feet from GR. Every piece of equipment powered up and maintanined power for 1 hour except the lights. (3) 1000w HPS lights with digital ballasts. Each ballast draws 9.6 amps. I obviously have an overload situation my question is: Since the 5 outlets in the GR area seem to be in a series or looped togather, which means that one of those outlets is the primary going directly to the 20 amp breaker. If I want to install a 50 amp service there would I have to re wire all of the outlets with 6 guage wire or just the primary? (I am assuming there is a primary outlet that would also have to be changed to a 50 amp outlet) Also, is there a reducer type items that would plug into the 50 amp outlet and allow for a regular 3 pole plug?

Thanks in advance

Hey I hit you up a while back on some service questions. Finally gettin around to installing n want to ask you a couple questions. I want to run 200 amps through 280 feet of 3 inc DB conduit. Got a chance to buy (3) 360 feet of 1/0 thhn copper wires for $1400. I was thinkin of cuttin the 360s in half for 6 1/0 and pullin them 180 feet to a splice box. then pullin 100' of 3/0 from my pole to the splice box. Would (6) 1/0 in a 3" conduit even be possible? cable fill? Dumb Idea? Tryin to save a few bucks. My calcs came up with 300 copper for 280". Thats gotta be pricey. Thanks for any help
