need electricians assistance, GVRD [bby]
hey,
a while back i was looking for some quick connect fittings to make extension cords for my MH ballasts. well i found some, and tried to put them together myself, and well... i did a hack job. plugging them in trips the GFCI. was wondering if there was an electrician among us that could help me out putting these extensions together. of course i would compensate you, some pocket change for an easy job, or frags if i have something you want. just let me know, thanks!

I'm not an electrician but what are the colours you are trying to match up?

If they have the same colour wires (ie.black,white,green) than simple logic is to just match them up.....if they have different colours well than its a little more complicated.

It depends on the fixture but normally the colours coming from a unit are black , white and green. If you are tripping a GFI, I suspect you have the neutral wire ( normally white and to the silver screw on a plug or socket ) and the safety ground ( normally green , but may be a bare wire in some fixtures with wires meant to go to a box rather than an extension cord) switched. Power wire goes to the bronze screw in a plug or socket on an extension cord or wall socket .

I'm a electrician. You can pm me with what your trying and I can try to help u out. Gfci's can trip for numerous reasons. Some ballasts leak current and can cause a premature trip. It only takes 7 thousands of a amp to trip when it sees a difference in current between the hot and neutral.

hey all,
i'm basically trying to move my MH ballasts further away. i have 3 250W vertex ballast hooked up to a fixture. but the quick connect cords on them are pretty short, so the ballasts are sitting on a fold out sidetable right beside the tank. to me, its a hazard, and a wiring mess. so i wanted to make these quick connect extension cords to go inbetween the fixture and ballasts so i can place them further away from the tank, and in a neat fashion. they currently work fine connected to the GFCI with only the original cords.

What type of cable are you using to extend the wiring, you have to be careful because standard nmd90 (loomex) is only rated for 300 volts and with hid lighting te strike voltage can run upwards of 400 Volts. The cable you use has the be 600volt rated sow cable (aka cabtire) would be a appropriate choice also the connectors that you use need the same voltage rating, note this is only for the secondary side of the transformer. The primary side would be ok

is the primary side from the wall to the ballast? secondary being from ballast to fixture? so this is the cable i used...  300V only... so this is my problem, and the connectors might be suspect too. oh well, learn something new everyday. there goes $50! lol.
