Experience

Education/Credentials
"The Frank Williams School of Electrical Construction". My dear old boss is 96 and still going God Bless him. I started working for "Tenafly Electric" right out of high school at 19. He was tough but I learned more working for him in 8 and half years than most guys. We did mostly industrial work while doing some commercial and residential so I was fortunate to be exposed to all 3 areas of electrical construction. The guys I worked with were all good guys and I stay in touch with some of them still. Most of us went into our own buisness's which says something about the caliber of the guys I worked with. We had some interesting clients : Wella Corp. of shampoo fame, Farah Fawcett etc, I didn't buy shampoo for 10 years, it was a great place to work. Pan Am the X airline just before they went under, another great place to work, nice clean environment. C&C Metals, the largest button manufacturer in the US, a not so clean environment but a very interesting place to work, lots of machine's cranking out buttons of all kinds but you had to be on your toes, it was a potentially dangerous place to be . All kinds of action going on around you.

Question
I want to install my Electric dryer and question is do I have to install three wires or four to the 240v line and what is the differience betwen those  

Answer
David,

You want to run a 4 wire line to your dryer which would be Romex (plastic outer covering) black, red, white, bare ground. Not to confuse the issue but with Romex the bare ground wire is NOT included in the head count of wires. In other words on the cable it does not say "10-4 Romex" it says 10-3 Romex but its understood that the 4th wire, the bare ground is present. So the difference between using this type of cable VS whats really a 2 wire cable with a bare ground is that with the 2 wire cable the bare ground wire is performing 2 functions: It serves as the "ground" in the event of a short circut and it serves as the "neutral" providing 120 volts to the dryer motor and heating elements. The 3 wire cable has separate wires for these purposes so its better and safer. Let me know how you make out David.........
