4 Prong 220v Recep. To A 3 Prong

I have a 220v Microwave, and a 220v dryer, that came with a four prong plug cords attached (they were used in newer homes).



The current outlets are three prong outlets and there is absolutely no way to run new wiring.





Just need to change the cords on the microwave and dryer to the old style three prong ones?









Opinions?
      

Hey guys,



I am trying to convert several 2 prong to 3 prong outlets throughout my house that was built in 1959. I have attached 2 photographs of the outlet, one from the right, and one from the left.



You will see the right side of the outlet has a RED and a BLACK wire attached to it. The left side has a WHITE wire.



I took the Menards employees advice that the black wire was most likely the ground, hooked it up, and blew a fuse (time delay fuses....). When I tried screwing in another fuse, it blew right away. This happened about 4 times and I got frustrated and decided to try this forum.



Any ideas as to which cable would be the ground, if any?? I'm pretty new to all of this. Any advice?



Thanks!
      

I have heard it is unsafe to plug faulty toasters into a 2 prong outlet as there is no earthing, however by design, the toaster's heating elements are kept insulated from the actual metal frame is this not so?, hence technically if there is nothing wrong with the toaster, this should be ok, correct?
      

Hello Guru's,



Can I throw a  standard 3 prong 110/120 receptacle on a 15A 2P 220v circuit? I need to run that 15A 2 pole 220 to a switch for central AC air handler service. I'd like to run to a switch with and outlet right next to it for service and still comply with NEC Code. This way, if service tech ever needs to plug a vacuum in or some other device, he'll have a something there. Is this possible or is that too powerful for 220v even though it's 15 Amps? Or should I just run a standard 15A 14/2 circuit.



Thanks

Hello everyone,I have a question about a forklift battery charger i bought. Ok,its an exide forklift battery charger 36 volts. It weighs a ton so i am having to run a 25 foot extension cord to it. My question is,my 220 wall outlet has three holes so i went to lowes and made a 220 extension cord. Now i get to the ac cable coming out of the charger that hooks to the extension cord(plug was cut off),there are 4 wires coming out of the cable green,white,red, and black......the guy at lowes said i could buy a 3 prong plug for it to plug into the female end of the extension cord because one of the 4 wires is probably neutral and i wouldnt have to hook up but the green,white and either the red or black.....is he right? Inside the charger the red,white and black all go to big fuses and green to ground. Also above the fuses it says "factory set to 480 volts ac". I guess my question is,will this charger only work using a 4 prong wall outlet(mine only has 3) and with 4 prong plug hooked to cable coming out of the charger itself or is the guy at lowes right in saying that only the red OR black wire has to be used? Sorry if this is confusing but ive searched and searched online for 3 days and havent found anything. Thanks in advance for any help-Kevin
      

Hello.



I recently purchased a home that has a a new grounded breaker panel but none of the outlets themselves are grounded save the hvac system in the basement. I had an electrician come and he said the fastest way to get it done is to switch the appropriate breakers to GFCI breakers in my service box and then I can change the outlets and then just put the stickers that say ungrounded etc on the new 3 prong receptacles. he called the inspector to double check and the inspector told him that he can't do it this way but he needs to find the first outlet in the loop from each breaker line and change that receptacle to a gfci and then we can change each receptacle to 3 prong in that loop.



Wouldn't just changing the breaker do the same thing? also if I did just install a Gfci receptacle on the first outlet in the loop, if it breaks wouldn't the rest of the outlets behind that gfci not function until I replaced the Gfci outlet where as a breaker would just pop and I can simply go turn it back on?



Just wanted to get some opinion from the experts as I'm willing to spend more on doing gfci breakers and am confused as to why the inspector suggested the way he did



Thanks for any help!
      

i am replacing a meile washing machine (220V) to a new LG that is 110v

i want to convert the present 220 plug to make a 110 outlet.

can i just use the black, white and ground and cap the red?
      

I'm replacing my electric range with gas.  The electric has (I think) a four-wire #6 or #8 cable approx 60ft run with a 40a dual post breaker.  I say "I think" because the wire is behind everything else in the panel.  I see red/white/black wires, but no ground and I can't read the jacket.  Once I cut the main, i'll have a closer look. 



The gas range requires only a 15amp breaker. 

Can I simply replace the breaker with 15A and the 4 prong outlet with a Nema 5-15p?  I'd cap off both ends of the red wire.  Is there some sort of code that says I need to maintain the 40A circuit for a future stove?

Or is there some sort of transformer I can plug into the stove end and avoid all that hassel.  ?
      

I'm new to the forum and I don't mess with electrical issues.  I leave it to the pros.  My question, I'm looking at buying an older home.  It is upgraded to a 200 amp panel, has 3 prong outlets, but the owner said he never ran a gound from the box.  What are the pitfalls / safety hazards of not having grounded outlets?  thanks,
      

How would you go about connecting a 3 prong gfci in the yard to an old 2 wire system from the house?
