electrical question

Captn. J · May 14, 2012, 02:50:26 PM

I have a hoist which will need a 220 to operate but i dont have a 220 in my barn yet but soon but i m gonna use generator to operate the hoist at times so now my question is the hoist has 3 wire coming out of the motor and i bought a plug for the generator which has 4 prong plug twist lock how do i wire this up? i ve been looking all over didnt get a decent infos. anyone here can help?

You wire it the same, the 4th wire which is green is a ground, just ground it to the frame of the hoist,

3 wire from the hoist and the plug has 4 prong which need 4 wires.... so i m short a wire now?

If your saying the generator has a 4 prong female and the hoist has a 3 prong male? then you need to either buy a 3to4 prong connector, which are real pricey, or just buy a 4 prong 220v wire and plug, you can get this at home depot, lowes, aco, etc. for around $20. the wires hook up the same as the three prong, white, black, red, the 4th wire is green it goes to the ground on the hoist. use a self tapping screw or put around a bolt.

On 220, red and black are hot, white is nuetral, green is ground. Everything used to be 3-wire, only the 2 hots and the white sort of doubled as nuetral and ground. Now there is a separate ground which is green. 110 has 1 hot and 1 nuetral, the black is hot and the white is nuetral. Green is always ground. Hook up the red, black and white on the plug and the green goes to the frame of whatever. Run all 4 wires from your new plug that goes in the jenny to the hoist. Hook up the 3 you normally would, and find a spot on the frame to hook the green wire to on the frame of the hoist. IF YOU ARE GOING TO WELD ON THINGS HANGING FROM THIS TYPE OF HOIST, YOU MUST HAVE A NON-CONDUCTIVE STRAP BETWEEN IT AND WHAT YOU ARE WELDING ON. THE ELECTRICITY CAN AND MOST LIKELY WILL BACK UP THROUGH THE CHAIN/HOOK AND FRY IT AND MAYBE YOU TOO.

like above u i said i will run wire later on but not yet prolly by summer ...

ok i looked again and the generator is a 4 prong twist lock plug i couldnt find a plug that already has wire on it but a plug alone where i have to wire to it myself .

and the hoist has 3 wire but 2 black and one green which i m sure green s ground for sure and what r the 2 black ones they says L1 and L2 ... so i m stumped kinda unless somneone can draw me a diagram?
i ll be hitting menards again to see if i can find something better or here

I would treat the 2 blacks as red and black, the green as a white.

Captn. J · May 15, 2012, 01:10:48 PM

so u re saying i shd get a 3 wire with ground for the 4 prong and wire it up and the ground goes to to frame of the hoist?

xjs3667 · May 15, 2012, 01:40:03 PM

yea the 2 black would be treated as one is red and one is black and green is ground, I personally have never seen a 220v twist lock plug, i've only seen em as 120v if you could get some pics it be great, also you said you couldnt find a plug with wires, they are usually in the like the dryer or stove accessories aisle.

Captn. J · May 15, 2012, 07:38:24 PM

ok i wanna make sure cuz the twist lock plug is on the generator , it did say 240v or 250 v will it be ok to plug that in? i can check into it tonight

old school truck dude · May 15, 2012, 11:03:19 PM

There is a 125 volt heavy duty rv outlet/plug that looks very similar to a 220/240. Make real sure you got the right voltages in mind. I plugged one in to a 220 outlet and burned up everything in my trailer years ago

xjs3667 · May 16, 2012, 12:52:25 AM

^^^ x2 make sure its 220v I mean being that the hoist is 220v, if the plug is only 120v then I guess you would just pop the breaker on it.

Captn. J · May 16, 2012, 01:10:30 AM

i ll check tonight and if it s a 240 or 250 v can i plug that in?

Captn. J · May 16, 2012, 03:51:46 AM

i looked again it says ac 120v/ 240v so i guess i m good to go?

xjs3667 · May 16, 2012, 06:02:56 AM

if its 120/240v there has to be some kinda of switch to switch it then.... I really dont know on that, my generator has a different plug for 240v

old school truck dude · May 16, 2012, 08:02:56 AM

120/240 means it can be wired either way depending on how many hots you use. 240 = 2 hots, 120 = 1 hot. Its not that complicated, just think of it like truck electric, its just AC instead of DC but it still works the same.

true but since its on a jenny and being the same plug, I would imagine it would have a switch, I couldn't see someone making a generator that you would have to rewire the plug every time you would want to change from 120 to 240??
