Dryer Plug

How to wire a dryer. Well the first question asked is always what size wire.? How many amps ?. Well that is going to depend on your dryer. Look on the back panel. But most if not all dryers made today are looking for a 30 amp circuit with 10/4 #10 AWG wire.


The Break Down. A 30 amp circuit means just that and nothing more or less. Why ? Well the wire the breaker the dryer plug the outlet are designed to carry a max of 30 amps. And more importantly the breaker is designed to trip if more then that. For instance if your dryer is pulling more then 30 amps and you have a 50 amp breaker on the other end, well lets just say you will big issues melted everything including a melted house. So stick with what you should have and not what someone gave you…


The Dryer Plug. Sure you can do something really dump and hard wire the wire directly into the dryer. But remember that 30 amp wire can be used to pull your car out of a ditch. So when and if that dryer goes on fire try to pull the dryer out of the house with that wire connected. Or servicing it and turning off the wrong breaker.Ok enough with that.

It’s a simple understanding. Newer dryers need 4 wires. A ground, two hots and a NEUTRAL. green, black, red and white.

Now the back side of the outlet. Connect each wire to the outlet as shown for your outlet. Tighten each screw nice and tight.

The Wire. You will need a 10/4 wire. This should have four wires and will have a orange cover like in the picture below.

The Breaker. Although your panel may look different rest assure the way it gets wired in will be the same. First off and most important turn the main breaker off. The two hots and it does not matter witch ones go where on the TWO POLE 30 AMP BREAKER. Your ground will go to the grounding bar and the neutral will go to the neutral bar. As show in the picture below.

The Neutral Wire. The neutral wire is very important on newer dryers. With computers doing everything from putting the cloths in the dryer. These computers, lights and what ever it has uses 110 volts. One of the reasons you need that neutral wire. It’s also the return path of the unbalanced.

The Hot wires. Now it doesn’t matter what color these wires are, they can both be black. but you’ll see that you’ll have a red and black. These go to the breaker as show.

The Ground Wire. Yup very important and if you don’t know why you should use a ground you really shouldn’t be reading this. Just use it, Ok. without a ground chances are the breaker wont trip if and when needed.

I’m buying a new oven, but on the specifications for the oven it says 40 amps and 240 Volts. My outlet is a 220V , 40 amps, would that work for the new oven even thou the spec says it requires a 240V to run the oven? FYI; i’m buying the oven from homedepot.
