The white wire and the bare ground wire parallel one another back to the panel box and are connected together and to the earth. The red and black are interchangeable but typically the red is connected to the right-hand side of the block. The bare copper wire was screwed to the metal frame or shell or the dryer. The three colored wires were attached to the terminal block on the back of the dryer with the white wire going to the center. The fourth wire was 12 gauge, bare copper. Three of the wires were 10 gauge a black, white and red. When electric dryers first came out 60-70 years ago they were all hardwired to the house (no cords were made back then).

However, this post will explain the logic behind the national code changes and how to handle these situations.įirst, let’s review a bit of history. I must admit that fewer and fewer homeowners attempt to connect up anything involving 220 V. Of course, they are irritated because they thought all they had to do was plug it in and start drying clothes. When they get home, they find that their house has a three-prong outlet and they don’t know what to do.
Often a retailer will sell the customer a four-prong cord (The current code). Second, a new dryer does not come with a line cord. If a person moves an old dryer to a new house they may be faced with an old three-prong line cord on the dryer and a four-prong outlet. Many different situations are encountered. Most folks are frightened away by the heavy wires and leave the job to appliance technicians or electricians. I have seen many novices cause a lot of trouble by mixing heavy and light gauges. Normal lamp cord wiring will get hot and melt. The wires are heavy gauge because the dryer heating element draws 15 Amps. For many people fooling with these heavy wires is very intimidating. Since 2000, electrical code states that four wires are required. For starters, the heavy cable used on an electric dryer may have three or four heavy wires.

It is very easy to understand why many people get confused when attempting to install an electric dryer.
