How do I wire from a 220 volt 30 amp breaker to a 50 amp receptacle for a Lincoln AC225 welder using ten gauge wire do I wire it the same as I would for 50 amps using two hots ground and neutral?

Answer for Canada, USA and countries running a 60 Hz supply service.
You don't. What you have to keep in mind is that the breaker protects the wire size that is connected to it. The #10 conductor that is connected to the breaker now has a capacity of 30 amps. This connection is correctly sized. If more that 30 amps is applied to the conductor, the breaker will trip. Changing out the 30 amp breaker to a 50 amp breaker means that the conductor will have to be changed to a #8 with an insulation rating of 90 degrees C. This size and type of conductor is allowed to have 55 amps applied to it.This new cable will terminate in a receptacle box where it will be connected to a 14-50R configuration plug outlet device. This is classed as a three pole four wire grounding device.
The new wire termination colours will be red to terminal X, Black to terminal Y, white to terminal W and ground wire to terminal G.
The new 50 amp breaker will be connected to the red and black wires of the new cable, White to the neutral bus and the ground wire to the ground bus.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself, on electrical circuits, equipment or appliances always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.

∙ 9y agoThe 30 amp breaker protects the cable feeding it, which can not supply more than 30 amps. For a welder taking 50 amps a 50 amp supply is required, with thicker wiring.

How do I convert existing 3 wire 220 volt 20 amp breaker wire system to 110 volt from the box to the recepticle?
Assuming there is no neutral: 1) Turn off the breaker. 2) Disconnect 1 of the 2 hot wires from the breaker and connect it to the neutral bar (Recommend phase taping the wire white :) ) Remember which wire you used as the neutral, in a home you will most likely have a black and a red. I would keep the black hot, and phase tape the red wire white. If it's not long enough you can wire nut another white wire onto it to make it reach the neutral bar. 3) Leave the breaker OFF, at the receptacle, change it to a 120 volt receptacle. Take the wire you made the neutral, and connect it to the white screw on the 120 v receptacle, and take the black to the hot. Ground to the ground screw. Make sure you phase tape the red wire at the receptacle white as well. 4) turn the breaker on 5) test the receptacle with a meter or receptacle testing device for correct wiring.
Why would your pool circuit breaker go off?
Probably because you are either drawing too much current or you have a ground fault. If your ground fault breaker is tripping, or if you have a ground fault receptacle is tripping then you have too much circulating current through your neutral. There are many factors to consider there. Provide more information about what is on the pool's circuit and we can explore the options.
Can you change outlet to fit old 3 prong outlet?
An old 2 hole receptacle can be changed to a 3 hole receptacle that will accept a 3 prong plug, provided a ground wire is available at the box and connected to the ground (green) lug on the new receptacle. A 2 hole receptacle has a hot and neutral wire, while a 3 hole receptacle will require a ground wire connection -- in addition to the hot and neutral wires.
If live is kept open could it trip circuit breaker by connecting neutral to ground?
I would think not. However, if live were to come into contact with either the ground, or the neutral or both, this would cause a breaker to trip.
Is a grounding 120 volt receptacle larger than an ordinary receptacle?
No, it just has an additional conductor to separate the neutral from the ground, and has a third prong in the receptacle to receive the appliance grounding conductor through the cordset.

Why is it good to a ground on a receptacle?
Not only is it good to put a ground on a receptacle it is mandatory by the electrical code rules. The ground is installed to provide a low impedance return to the distribution panel to trip the breaker supplying the circuit in case of a ground fault occurring on the circuit.
What is A ground-fault circuit interrupter?
== == If the current in an ac power circuit is not balanced between hot and neutral, possibly meaning some of the current is going through a human being to ground, a GFCI breaker or receptacle will break the circuit to keep the person from being electrocuted.

How can you wire a 110V plug outlet from a 240V plug outlet not speaking of a converter but actually changing the plug outlet so that there are no long term effects on the 120V appliance?
Assuming the wiring to the outlet has 2 loads and one neutral, isolate one load from the outlet and use the neutral as the common. be sure to ground from the receptacle to your conduit or ground lead. You should also replace the corresponding breaker with a 120 volt single breaker.
How do you wire a 15 amp breaker?
Ground wire connects to the ground bar, white wire connects to the neutral bar, and black wire connects to the breaker. Be sure and turn off main breaker before installing the wire or the breaker.
Which prong of an outlet is live?
Looking at a duplex receptacle the right smaller slot is hot, the left larger slot is neutral and the u ground is ground.
Why are the GFCI breakers nuisance tripping in your 100 amp sub panel- is it because neutral bonded to ground?
It may be the GFCI breaker is defective. Make sure it is wired correctly. Neutral to neutral bar and ground to ground bar.
