one last will be i have a romex cable i think its 3wire 10awg and know thats the least common...would it work to connect the 240outlet or its best that i use higher and 4wire........

Answer 1

Two things you should never do as a home owner.



Play with electric.

attempts heights above 8 feet at a degree angle of 45*or more without a safety harness.



unless you know what you are doing and it appears you don't in your admittance. I would call an electrician, unless you don't think your life is worth more then the cost to connect a washer and dryer. But that is your choice.



yes 240 comes to the box and yes 2 -120 outlets will produce 240 but not in the manor you described. an dangerous combination regardless.



there is a good reason why it calls for a 240 50 amp breaker. and the wire size would not support that AMP rating. On the main panel you have three wires, 1 - black, 1 - red, and 1 - white, plus and earth ground. that is the complete four wire system arrangement. it is true 1 black and 1 white will create 120, but never ever combine to 120 circuits to make a 220 connection.



that is unless you have a death wish. remember it only takes 1/2 an amp AC to kill the average person.



God Luck

Answer 2

Home Depot & Lowes and similar stores offer a softcover electrical guide for the proper way to run circuits to code. Between the pictures and the text, is superior to this service.



There are two phases (120 v legs) coming into your home. To get 240 volts you must use one from each. It is also critical that you run them from your box so that the breaker handles are bridged so that if it trips, ALL power is shut off. Don't try to mixmatch nearby wires.



The book mentioned above will advise you about the required wire size (gage) and circuit breaker size along with the detail plate on the back of the dryer. Book also discusses the 3 prong/4 prong dryer plugs.

Answer 3

a 240v run is strictly for a 240v run. if you do anything close to what you are saying the wire will overload and catchfire inside the walls from the panel to the outlet.



for the dryer, must be 240v. but, the dryer pigtail can be changed by swithing it with the one that matches the outlet(common problem with moving from rental house to rental house with washer/dryer hookups).



a switch out of a wall switch is different that running a new run to the panel and adding another breaker. be careful. 240v hurts like a m.f.er. pay an electrician for the hookup, but, run the wire yourself per their specs, saves for paying the big part of labor costs. but, you are paying an "electrical doctor/lawyer" for their advice, education, and expert work.
