Do you need a neutral when running a BLK Red and ground from a panel directly to a 240V 4800W 20A heater outlet?
No. The black is 220, the red is 220, and the ground serves as the neutral. the last answer "no" is correct but the reason is not. the ground is still a ground. the red is 110v and the black is 110v. together they are 220v. the neutral or (common) is for a 110v return. for example a stove or a dryer will have 2 hots a common and a ground because they use 220v and 110v. 220v to power the heating elements and 110 for the controls, light bulbs or the outlet on a stove. A construction heater only uses 220v and only requires the two hots and the ground for safety.
How do you wire a 240V stove plug if old stove was hard wired and had 4 wires Black red white and ground coming from the wall are three wires Black red and a shield wire is the shield wire the neutral?
Shield is ground. White is Neutral, center tap of the transformer from the power company.
What is the difference between a 4 prong dryer outlet and a 4 prong stove outlet?
The four blade dryer plug brings a separate ground wire from the machine to the electrical grounding system. The three blade dryer plug depended on the neutral wire of the plug to make this connection.
When the green wire to a 220 stove cord is not in use does it have to be capped or can it be left exposed?
The ground wire must all ways be used. This is your first line of defence if a short circuit occurs. It is the current return path that trips the breaker and disconnects the load from the main service panel. The green wire on a stove cord, at the stove end, must be connected to the frame structure of the stove. Look for a ground lug or ground screw to connect to. If you can not see one, pick up one at a local DIY store and install it. Safety first.
Your electric stove has a 3 prong plug your new stove has a 4 prong stove you bought a new 4 prong outlet but on your old outlet it oly has 3 wires no ground wire how do you ground it?
Look in the back of the range receptacle box that is in the wall. The three wires coming in should have a bare ground wire in the cable set. It wasn't brought to the receptacle because there was no place for it on the three wire receptacle If you find it back there under a screw terminal just add another short piece of wire under the screw and then connect the other end of the short wire to the new ground terminal on the new four position receptacle The wire should be equal in size to the size of the wire that exists around the ground terminal now. If the house is so old that the range cable did not have a ground wire in it the code allows a separate green ground #10 wire to be taken from the breaker panel box to the existing range receptacle This wire is to be bonded on each end. At the panel end to the ground buss and at the receptacle end around the ground screw at the back of the box unbroken and then to the new four position receptacle ground lug.

When wiring a kitchen stove must the ground wire be grounded?
Absolutely. You need the range ground to be fully connected back to the panel ground buss bar.
Can you replace the 4-wire cord with the old 3-wire cord on the back of a new stove if there are only 3 connections and two wires go to the same place?
You need the neutral lead to run the control circuit of the stove (115vac), if a later model unit. Line 1 and 2 give you the 240vac to run the elements. The ground should not be used as the neutral by code and for safety reasons.

Older 3 wire stove to a 4 wire receptacle?
You have to purchase a new cord assembly that is designed specifically for ranges. Hardware stores usually carry these cords. Tell the salesperson what you want to do with it and they should give you the right one. On the back of the stove you will find a terminal block with three screws in it. Your newly purchased cord will have 4 wires in it. Red, Black, White, Green. Connect the red wire to the first terminal screw (left). Next the white to the center screw and finally the black to the last terminal screw (right). You are now left with one green wire to connect. There might be a jumper strap from the white wire "neutral" terminal position to the chassis frame of the stove. This must be removed. There should be a ground lug that is bolted to the chassis of the stove. If there isn't a ground lug install one in the place where the jumper strap connected to the chassis frame. There might be a ground lug in the four wire stove kit that you bought, if not buy a #6 ground lug. Put the green wire into the lug and tighten. Make sure the stove receptacle that you are plugging into is turned OFF. Plug the stove into the receptacle. Turn the breaker back on. Stove should be up and running.
What gauge wire should be used on 50a 250volt outlet for range?
#6awg ponypomp- Use 6/3 w GR,when installing new stove, that is,it has four wires, 2-120v hot legs,one neutral, one ground. New codes in certain places require neutral and ground. Its just a safer set up. Most old installations are only three wires. Remember you also need the 4 prong appliance plug and outlet.
How do you connect a 3-wire stove to a 4-wire outlet?
Answer for USA, Canada and countries running a 60 Hz power supply service. In order to plug your 3 wire stove into a 4 wire outlet, the easiest way to do so is to change the cord on the stove. This does not require cutting power to the outlet or anything like that. Anyone who is going to be changing the power cable on any device knows that you need to unplug the cord first, eliminating the need to cut power to the outlet. The difference between a 3 prong and 4 prong outlet is the ground wire. Both provide 240v power by supplying 2 120v wires (red and black). There is also a white wire, which will be your neutral wire. The green wire is your ground, and should be bolted to the body of the stove. (Most appliances have a location for attaching the ground wire). When connecting your wires, there should be 3 wire locations. You should connect one of the two hot wires (red or black), then your white wire in the middle, and then your other hot. The green will be your ground.
Does the green ground wire have to be grounded to the stove?
Yes, the ground wire should all ways be connected. This is the short circuit current return path that trips the breaker in case of a short circuit in the unit.
How can you put a 4 prong plug on a 3 prong plug stove with 220 volt?
You can do it, on the four prong plug you have 2-hot(120v+120v=240v) 1-neutral 1-ground, on a 3-prong plug you have 2-hot and 1-neutral but no ground. on old electrical systems the neutral and ground bar were wired together. and that system worked fine,now they are isolated. There are no adaptors to do this you will have to change the oven pigtail with a four prong one and use 2-hots(black and red wires) and connect the neutral (white wire) to the green ground wire and attach the green wire to the metal body of the stove or change wall outlet to a four prong (although this is not recomended) you'll have to see if your panel has a isolated neutral bar. Best left to the pros as one wrong touch will give you a one way trip to the pearly gates. Hope this helps. p.s. I've found most ovens will have instructions on how to connect ether pigtail to it ,if its old hop on the net go to mfg.website put in model # usually there are installation manuals avalable.
