what to do about using a plug that isnt grounded?

can you safely run a 250w system, and a 40w inline fan from an ungrounded plug?? what can you do to ground an ungrounded plug? thanks in advance.

You can buy a 3-prong to 2-prong adapter. There is a little loop coming off of the adapter - hook a wire up to that and then hook the wire up to a radiator or some other grounded item in your room.

if it's a permanent setup, or you like doing things the right way the first time...

if it's a permanent setup, or you like doing things the right way the first time...

goto the electric supply and get yerself a junction box, a length of grounded heavy duty cable, and a grounded heavy duty plug...o yeah you'll need tape and a few wire nuts too.. total cost: $10 (if you have a phillips screwdriver and dikes)

rewire the fucker and you can also hook the fan up to run with the light if you want, it's a cooltube i'm assuming :confused:

ps- :respect: ambre on the Guruness :D not trying to undermind anything you said just this is the proper way to go about it. thanks :)

if the wall plug's not grounded, it doesn't have an additional third wire, running back in the walls, to eventual earth ground,so adding the third green ground wire to your equipment isn't going to do anything for you.

With all that water around, grounds are very good ideas; but if the grounding line is interrupted anywhere along the way, it won't function as a working safety device anyway; just like if your power wire is interrupted anywhere the things won't come on...

i'm not sure if what you're saying, is that the wall recepticle is ungrounded, or not;

CJ-

I was assuming that he was in an old house that doesn't have ground wires built into it. As far as I know, rewiring the outlet alone isn't going to help. I'm old enough to remember when grounded wiring was new and I remember how we adapted until we moved into a newer house that had a proper grounding built in.

viable,

if the box that the receptacle is mounted to is metal and the conduit is metal, all you have to do is swap out receptacles for one with a ground. then just run a small wire from the receptcle to the box. it will act as a ground. seeing as how all the condiuit is also metal......

like you said though, with all the water around the way to go is gfci's

this is just me...

this is just me...

both fire and electricity scare the shit out of me...

all of my equipment is GFCI protected, and grounded.

fire extinguisher and smoke alarm installed...

i had an electrician run the power supply.

i realize that bringing in an electrician is IMPOSSIBLE for most, but i like to sleep at night.

get a book on household wiring at Home Depot or something.

sorry for the rant.

best of luck to you. :sasmokin:

outlet?

outlet?

he asked how to properly ground his device, not his home...
a junction box......as in, to make splices in, ambre..where did the outlet come in? im done here, listen to sleepy sourdog.

peace out

ren: roger that. i assumed he's in a typical house run with romex instead of conduit; additionally i kind of secondarily assumed that with conduit, if the house is so old there aren't grounded recepticles (plugs) that through the years some of the conduit nuts/joints could be loose.

If he's indeed talking about a male plug, (it's not really perfectly laid out what the situation is) his light is almost certainly wired with a ground; the fan and light together using a two prong plug would indicate to me maybe he has extension cord or power strip.

hard to say what the situation is without sourdog saying what's wired how..

You both are right in your own way. How I would do it is similiar to my man the CAptain. Your home is most likely grounded. You can check by pulling off the cover to the outlet. I'd highly suggest turning off the power to that circuit first (unless your me)
If their is a third wire (bare or green) its grounded or if your shit is in metal conduit, do what REn said. wire from ground lug on the recepticle to metal box. The buy your self a 14 gauge extension cord longer thean you will need to reach the farthest object, junction box, and 3) 1/2 romex connectors. Take the extension cord and cut the female end off. Figure out where you will mount the junction box and cut wire from receptical to length. Take the rest of the wire and run it to you fan and light(id suggest separately but you can run them together if you wish or are confident enough). You should have a black or red(hot) white(neutral) and a ground(green/bare). Attach the hot wires of your fan and light to the black wire and the other two wires to the white side. Match colors inside junction box and hook up the three sets of wires together but separate by color. This will leave you with that extra ground you so badly need. Be sure to make all the connections INSIDE the box and/or LIGHT AND FAN ! !
Connect that extension cord to a GROUNDED timer and BLAM ! ! !

I hooked up one of those 3 prong adapters and didn't ground it and it still works... Should I ground it or does it matter?

You've already heard the opinions.

If you value your health or your grow i'd hook it up.

Do you want me to hook it up for you?

I live in a very old house and use these adaptors in almost every room... the house is so large as far as space... i need alot of adaptors aswell as extentsion cords to use things properly. The grow is no exception. Now i dont know all this Eletrical mumbo jumbo, BUT... I have been able to run an 600 HPS, Plus a medium Size A/c (Dont know the BTUs off hand) on full blast with two turbo fans.. 24 hours a day. All with no problems... This with everything else in the house being used too. No surges or anything.....I going to get another 600 and add it soon i dont think i will have any problems because of winter i dont need to use the AC anymore.....

Smoke Alarm, Fire extinguisher are more important than Genetics.

The only thing you can do if you don't have the grounded recepticle, is go to the store and buy a GFCI recepticle, and put it in, in place of the old one. It has a tiny transistorized comparator circuit built into it that constantly monitors whether the electricity coming in, is all going OUT, the correct wire. if not- for instance some of it's going through you or other path, it instantly trips the circuit before people make a being dead, or extremely excited sound. Or, befire the house starts making a catching-on-fire sound.

All sounds, you want to avoid, probably.

The wattage of the light, etc, all that, in THIS case, aren't part of the consideration for having a ground. The ground wire is completely separate from the electricity carrying part of the house wiring; it's just a wire run, from box to box, with that third hole, to access it, and it goes back to the household ground; this is to ensure that if any part of the house wiring or any equipment ever gets a hot wire touching part of the equipment/household structure, it will have a way to carry a bunch of current back and flip the circuit breaker.

grounds aren't installed to keep people from dying; that is what a GFCI is for; Grounds are to keep fires from starting.

220v+50a=DEATH

Go outside to anything carrying REAL current and there WON'T be a GFI.
Thats what BREAKERS are for.

WOW.........boy's n gurls...... fights over a plug?.....lol

check it sour...... trip the braker pull the plug out ( 3 screw's ) see if theres a 3rd wire
if so go buy a new grounded plug ( 53 cents )

if not put it back in trip braker back on.

plug in light.... ( j/k )

if thres no 3rd line i wlound go to the depot n buy enuff 3 wire 120v power cable n run a line to your room.....

or the hard way...... go buy a 10 foot rod.... pound it in the ground 8 foot's straip a wire to it....... n run that to your room....... thats all a ground is....

but hey just fyi lights are only 2 wire's the ground ( green) in the ballast is hooked to the case witch probly dose jack shit.....

i allway use a ground... i even make sure my timers have a ground... a lot dont

stay safe so u can grow/ smoke lot o weed

here in the states,
you will often find in a home old enough to have only hot and neutral run to all locations... you find that the metal boxes are often all grounded by a wire you cant see after the wall boards on... it terminates outside the box... not inside where is reveal by removing the outlet.

hook a pigtail of wire to an aligator clip and use a 3 light led circuit testor or something to see if you have ground right there as the box.

later
