you might have to buy a female and a male, then wire them together with the correct polarity.

Use 240V hubbel locking plugs.

Re: need help with a 240v adapter/plug for my welder/heater
 

bare wires, jam them into the socket and duct tape the wire to the recepticle until it stops moving around. or jbweld the wires into the socket

Re: need help with a 240v adapter/plug for my welder/heater
 

I think Iam going to cut the ------- plug off and put a new one on. What do I need to know about wiring this bitch up?

Re: need help with a 240v adapter/plug for my welder/heater
 

2 hots a neutral and a common.

Re: need help with a 240v adapter/plug for my welder/heater
 

Ok if its a two vert and one ground thats 115, one vert one horiz is a 20A+ 115v, and two horiz are 220.

Simple to do single phase.
115V 15A - 50A service you use single breaker, use 10/3 or 8/3 Romex wire. On the outlet brass hooks to the black(hot) silver to the common(white)
and green to the ground.

220 50Ax2 service uses 2 breakers, use 8/3 or 4/3 Romex wire. Your black wire hooks to breaker 1, white wire to breaker 2, and bare or green to common. When wiring the plug up the black and white are hooked to the blades and common to the round.

Re: need help with a 240v adapter/plug for my welder/heater
 

4/3? WTF? That's confusing. :S

It's only a 2 wire plug. It's either 2 hots and a ground(220v) or a hot, neutral and a ground(120v).

Go to the hardware store or HomeDepot and get the right plug. It shouldn't take more than 5 minutes to swap them and cost around $5. :1

i have the same plug on my welder, but i didn't understand his post until he edited it after i posted.

Re: need help with a 240v adapter/plug for my welder/heater
 

There we go, Dr Boost FTW! Does it matter which hot wire goes to which termainal? The two hots on the plug are different sizes.

Re: need help with a 240v adapter/plug for my welder/heater
 

lol, seriously? ??? If the two hots are different sizes....that's crazy. Are you sure? It doesn't matter which hot goes to which terminal.

Ya one spade terminal is wider then the other like some 110 plugs but I dont know why since it has the top ground so its not like you could ---- that up. Thanks MrBoost :)

Re: need help with a 240v adapter/plug for my welder/heater
 

Oh, I thought you meant the wires were different sizes. :P So is your welder a 110v? What about the heater?

I was relatively drunk when I wrote that its 2 hots and one ground. Other than that the rest is correct.

Re: need help with a 240v adapter/plug for my welder/heater
 

both are 240, both have 3 terminal plugs. :)

Re: need help with a 240v adapter/plug for my welder/heater
 

Ok Romex "codes" 14/2 is a 14 awg with 2 wires in the shealth. AWG/Numbers of Wires

Re: need help with a 240v adapter/plug for my welder/heater
 

Actually there is 3 wires, black, white and a bare. :P There is no 4/3 romex.

ground is assumed in wiring, it doesn't actually carry current like hots do.

Re: need help with a 240v adapter/plug for my welder/heater
 

You can buy 14-2 romex with or without a ground. :P

I dont know, but thats what I'm told. Hes been doing it since power was discovered

Re: need help with a 240v adapter/plug for my welder/heater
 

Dang! He must be smart! :o Ask him how many feet of 8-2 I can run before I have to upgrade to 6-2 due to the length of the run, also assuming this is for a 50amp air conditioning condenser with a seperate FAU.

anything over 200' at 50A he recommends using 6-2

Re: need help with a 240v adapter/plug for my welder/heater
 

Boostie arn't you a master electrician? :1

Re: need help with a 240v adapter/plug for my welder/heater
 

Ground is NOT assumed. It is part of the count. 14/3 is two carriers and a ground.

Re: need help with a 240v adapter/plug for my welder/heater
 

No grounds not assumed, and it doesnt always have two hot leads its one hot one common(neutral).
14-3 is 3 wires all coated, 14-2G also has 3 wires two are coated ones not. 14-2 has two coated wires.

Re: need help with a 240v adapter/plug for my welder/heater
 

Obviously they are not designated hot/neutral/ground.


I didn't know about the "G" though. Thanks for the info.
