Question.....Wiring 220vac on lincoln crackerbox too 50amp RV ?

fordy · #1 08/12/11, 02:38 PM

...............Lots of The Red Lincoln Crackerbox welders available for sale on C's L ! Here , in the RV park we have 30 amp and 50 amp plugs , the 50 amp plug has (2)110 Ac legs and a Ground , the plug looks just like, and probably is an old 220 volt plug , 2 hot legs and a ground ! But when hooked too an RV the 110 legs never combine too give 220 volts , so I was thinking I could hook a 220 volt ac crackerbox welder to the 50 amp RV plug andit should work ! ??? Comments , suggestions .....thanks , fordy

That is what I have mine plugged in to.

Fordy,

Take a multimeter set for volts ac and check between the two hot legs to be sure that there is 220 to 240 volts. You don't want to hook the welder to 110volts when it needs 220.

Check the welder for a plate that lists what voltage and amps it needs. Find the circuit breaker for that outlet. The amps should match the amps the welder needs and be a 2 pole breaker for 220 volts.

If the amps and volts match and the plug fits the receptacle, go for it.

The only thing I can think of that needs both 220 and 110 volts is a stove. It needs 220 for the stove and 110 for the clock. The plug has 4 prongs, two hot, a neutral, and a ground.

Don't combine the two plugs to get 220v. That just sounds like trouble.

Do a meter check on both legs of the 220v. plug. Check from hot leg to ground for both legs and then check from hot leg to hot leg. If you read 110v on both legs to ground and the 110v from hot leg to hot leg, then that means both legs are hooked to the same bar in the panel or their is a jumper wire from one side of the plug to the other side of the plug.

I would check inside the panel first to see how they got the circuit wired. If your not familiar with panel boxes you should get a qualified electrician to do the job for you.

.................I'm going too check each hot leg in the next couple of days . I'm pretty sure there is just one ground and one neutral . The separation of circuits is accomplished in the RV panel . I've got to get the park mgr. too unlock the 50 amp panel so I can measure the voltages , all the 50 amp plugs are covered and locked so someone musta plugged into a 50 amp before I got here and didn't pay for the extra power . , fordy

Fordy,

Comming into your house and circuit box are 3 wires. One is usually a bare cable and two are insulated. The bare cable is the neutral. The two insulated wires are the hot legs. If you connect from either hot leg to the neutral you get 110 volts. If you connect from one hot leg to the other you get 220 volts. The ground is a wire from the circuit box to a water pipe or a rod hammered 8 feet into the ground. The ground is a safe path for the electricity to take in the event of a short.

The circuit box is set up so that every other circuit breaker is on the same 110 volt leg and the others are on the other 110 volt leg, A 220 volt circuit has a breaker twice as wide as the 110 volt ones so it taps into both hot legs.

Check that the breaker for the welder outlet is a 220 volt breaker and that the amperage matches what the welder requires. Check that the voltage between the hot slots on the outlet is 220 volts using a multimeter. ( I am assuming that the welder is a 220 volt model) If the plug on the welder matches the outlet, then have fun.

The RV doesn't have any 220 volt outlets, as you say. It is wired so that some of the circuits connect from one of the 110 volt legs to the neutral and the other circuits connect from the other 110 volt leg to the neutral. If each 110 volt leg has 50 amps then the whole RV has 100 amps. This is why you would run an RV off a 220 volt outlet.

Nimrod is right. RVs do NOT typically have any 220 volt circuits or appliances. An RV plug LOOKS like it might be a 220 plug, but it isn't.

I'm not sure what you are trying to do, but if you hook 220 into your 110 RV, you are going to be a sorry camper.

................Have no intention of running 220 into my 5'ver ! I'm just want too use the 50 amp RV plug too power a crackerbox welder . , thanks , fordy

I think in today's world the nuetral is not bare? That will lead to people confusing it for a ground wire, which it is not..... I see you have it straight, but it bothers me to call the nuetral wire a bare one - I'm not familiar with them doing it that way.

If the RV plugs are the new style 50 amp plug they WILL have two hots and a neutral servicing the pedistal from the main circuit panel (look at the main panel box and see if the pedistal is being served by a double pole breaker). If they are bootleg 50 amp, they will have one hot,one neutral feeding the base of the pedistal with the one hot "split" at the bottom of the pedistal and a wire leading up to each leg of the plug. As others have said. On a true 50 amp RV circuit, meter check should show 110v from hot to neutral and 220 v from hot to hot leg. A bootleg 50 circuit will show 110 hot to neutral and 110 hot to hot

At both the house I had in the Cities and the cabin there are 2 wires (hot) twisted arround a bare cable (neutral) comming from the post to the house. The bare cable supports the insulated wires.

Fordy wants to plug the welder into an outlet that is supposed to be where an RV plugs in. It should be 220 volts but check it first.

I use to go to one particular auction company estate auctions a good bit. They had a lunch wagon set up. I followed the cord it it to inside the house where it had a Y splice with a 3-point 110v plug on the end of each Y. Plugged in to a stardard double receptical.

I'm going to Europe in about two weeks and need to recharge camera batteries. Years ago I found an International Electricity Converter/Adapter. Several different set of prongs and then a standard 110V plug in on each. I'm taking along one of those adapter where you can put an electric bulb into a wall plate and two 15w bulbs. If it doesn't blow out the bulbs, I'll try my recharger.

Just replaced my 220 extension cord for my crackerbox Lincoln...

If your crackerbox plug doesn't match your 50amp RV outlet plug, you could just engineer a short changeover cord, the male to fit the RV camp's 50 amp outlet, and the female to fit the crackerbox's male plug. Only had room in my 'female outlet box' for three wires... two hots and a neutral...

Finally had to fix my crackerbox, as the wire welder just wasn't holding my broken hydraulic cylinder like it should...

Check the voltage and frequency rating on the charger. Most modern electronics will work on 100-250VAC 50-60Hz. This means you can plug it in just about anywhere and be fine, you just need an adapter to make the prongs fit.

Its possible that the rv has two 110 legs, coming off the same side in the main panel. If that is the case, they will both be 110 to ground, but will have no voltage between each other. To get 220 one leg has to come from each side in the main panel, they will still be 110 to ground, but 220 to each other.

There is not a worldwide standard for electrical recepticals. Different:

Africa, Great Britain, Ireland.

Europe-East & West, Middle East, Parts of Africa, Asia and South America.

Australia, New Zealand, Argentine, Mainland China, Figi.

Caribbean, South America, Tahiti, Philippines, Japan, Mexico.

I suspect not all of these operate standard off of 220v.
