I was wondering if you actual electricians could take a look at my shiz and see if there is anything I have done wrong.

Thanks!

hey i have 4 54w t5 bulbs and was wondering if it would be any cheaper and not to difficult to make my own fixture? Also i know that i would need ballast and sockets,is there any other components that would be necessary other than homemade fixture of course.thanks for any feedback.

Earth on the left, Neutral in the centre and SL on the right. If it can be used Should i just use 2 core cable? Live/Neutral into Live/Neutral connections? The "SL" connection is (I'm Guessing) Switch Live for the built in Timer and don't think i would be using it? Or should i Bridge the SL to Live and wire up Live and Neutral as normal?
Many Thanks if you can help
Forgot to ask. What size Fuse should i use ? 3AMP, 5AMP or 13AMP? The fan is rated 50Hz 15Watt.
[/B][/B]

i dont know what a 2 core cable is ? sorry , im a dumb american....

is what your calling "live" a forth connection ? if not then you should be able to run the hot wire to the SL an the neutral to the neutral an ground to earth an it should work fine, then you could run a switch if you want to , but its not necessary.

if the "live" thing is a forth connection then you would wire the hot to the live then the same as above.

your electricity is a tiny bit different then ours but we can get through it.

a 3amp fuse is fine for that fan. you can get a cheap "good fan" these days , they are a LOT more efficient. (as long as budget is right :mrgreen:

i am pretty sure the ballast will cost as much as a cheap fixture , but i may be wrong fuckin with T5's. those fixtures are outragous.

of course you can do it yourself , all you need is what you already mentioned. (ballast an sockets an maybe a few small wirenuts)

Hello wyteboi, Thanks for your help & No-one is Dumb Here if this Site is All about Learning ;-)

2 Core Wire/Cable is just Live (Brown) and Neutral (Blue).
3 Core Wire/Cable is Live(Brown), Neutral(Blue) and Earth (Yellow/Green Stripes).
I've just found this Pic. on the Net:

As you can see, There isn’t an Earth Connection on the Fan. Only a Live, Neutral and Switch Live.
So if i cut a piece of Live wire about 1 inch long and connect it to the SL and L.
Next connect the Neutral Wire to the N and the Live Wire in with the L.
Does that sound right to you so far? And a 3 AMP Fuse in to the Plug.
Oh, And I’ve got no budget again like my First time growing MJ earlier this year lol...... I've just Spent it on a new 1.2x1.2x2.0 Grow Tent, 600Watt Duel Light and Ballast & Shade & New Beans (Pineapple Chunk & AK47) + More.
But forgot about Fans... Thats why i'm doing this lol....

Rotweiller · Nov 7, 2011

I've just done this quickly

1 Inch long- Live(Brown) Jumper Cable = SL into L.
Main Cable with 13 AMP Plug on the Other End = Live into L, Neutral(Blue) into N.
Is this Correct and Would it work ?
Thank you for the Help from an English man who needs a Joint :-)

where is the switch that was supposed to control the fan ? it would help if i seen that.

in the us , our switch to that paticular fan would be the standard wall switch. did it have a light built in it at one point ?

so far i am thinking you are right on the wiring , but i will come back with a for sure answer.

if thats your fan/light in the spec photo you stole, :mrgreen:

then try to take that jumper out an just use the L an the N an that should fire him up.

i think the SL is to turn the light on separate from the fan.... so it would need no power if your not usin it.

the fan in the link has a timer built in so when you turn the bath light on, the fan comes on and when you turn the light off, the fan continues to run for a minute to clear the air.the SL terminal is a trigger to turn fan on and start timer when de-energized.

only downside to making your own fixture is it is not UL approved so in the event of a fire, it WILL be blamed for the fire & your homeowners insurance will give you shit. this happened to a buddy last yr when his garage burned & insureance co f@cked w/ him till he produced reciepts to show all electric was done by code and all devices met UL. btw, grow was not legal but since crop burned to ground,nothing was left to charge him with.

Thanks cow !
if this is correct then your wiring should work with the jumper you made. i would try SL an N first then if that dont do it then add your jumper back in.

sorry for all the confusion , like i said my skills are limited to n america.

Rotweiller · Nov 8, 2011

Thank you wyteboi for your much needed knowledge and expertise ;-)

I'll give it a try on Wednesday night and see what happens?
If it works out OK I'll let you all know and take a few Photos for Reference in case anyone else might want a Cheaper Solution for Intake/Out-take Fans as you can pick up these type of fans quite cheaply now (without the timers built in them) for about £5/$11 New (if your on a Tight Budget).
If it doesn't work, once I’ve dug through the chard remains of my house and found my laptop lol.... I’ll have to think of another solution...
Anyway, That's Defo worth a Beer and a +Rep ;-)

You will have to come and pick up the Beer though ;-)

Rotweiller · Nov 8, 2011

Hello MrM. Many thanks for your Help as well. I couldn't have done it without you both. So Fingers Crossed it should work OK ;-)

wyteboi · Nov 9, 2011

if it dont work (it will) then it wont pop or nothin, it just wont work.

defiantly come back an let us know.

i would come an get the beer but your dog dont like me , i can tell from the pic :mrgreen:

i'll just bring my dog an let them occupy each other...

Rotweiller · Nov 9, 2011

LOL... My dog Loves Everyone But the Postman & Garbage man...Ha Ha...
And wyteboi... Your a STAR... It work's like a Dream...
I left the Fan just as in the Photo with the jumper cable bridging the SL & L.

It has now been Running for 7 hours and my Temp's have gone down to 80 Degrees and is Steady as a Rock...
The only downside is it isn't the Quietest but if I shut the door you can't hear it ;-)

Once I get a Filter for it that should stop most of the noise.
It isn't the motor that’s noisy, It's the HUGE Amount of Air it's throwing out ;-)

But All in All... FANTASTIC...

I would like to run two 30 single pole amp circuits for my lights, and i was wondering what kind of wire i should run for 30 amp 120 V circuit, or would you suggest running a 220 v two pole circuit?

supernovagrowlights · Nov 9, 2011

you can use 10ga wire on 30a circuit, dont know how your box is setup , but if you run 208 or 240 you will be able to fit more ballasts on that circuit
