There are two approaches to make the warmth required to drive garments, gas, or power effectively. Before settling on a gas or electric dryer, it is helpful to look at your hookups.
Most contemporary homes come equipped with a 240-volt electrical socket larger than a conventional socket and consists of four or three holes. Alas, few homeowners know that the vital differences between 3 Prong Vs 4 Prong Oven Outlet.
In a bid to inform homeowners of this critical issue, here are the gaps between these strings and why 4-pronged hookups are getting widely used by homeowners.

The Objective of the neutral wire on the 3-wire cable and plugin setup
It’s the return route for the 120-volt heaps that manage the range’s clock, timer, light, etc., plus it conveys that present back into the 240-volt source.
It was attached to the metallic framework and casing this range, so it might trip the circuit breaker when there was a brief into the floor.
The problem with this configuration was that the machine might not necessarily go to the circuit breaker. A good example would be if the 3-prong’s neutral wire were not on the metallic frame and casing of this appliance. When there’s absolutely no return route for the current to return to the origin, then the metallic case is still energized, and it may cause a shock to a man who touches it.
The Objective of the 4-wire cable and plug setup
The equipment grounding conductor (the 4th cable ) currently functions as the conductor connected to the metallic frame and casing of this stove.
The 4th cable’s purpose would be to return some fault current about the metal in the event of a short to ground position.
The NEC prohibited the cable from being on the metallic frame and casing for any new construction in 1996 and afterward.
From the laws of mathematics, the neutral wire shifting current will follow the course of least resistance. Electrical present on the exposed metal might easily make contact with a human being to keep its route, which explains why the NEC altered the requirements for floor links on 240-volt appliances.

What is the Difference Between 3 Prong Vs 4 Prong Oven Outlet?
If you reside in a house which has been constructed before 1996, the socket for your kitchen stove may still call for a 3-prong cord. It’s, in actuality, considered code-compliant to keep on employing the 3-prong configuration in pre-1996 houses.
Why is this date significant? The National Electric Code (NEC) upgraded their needs 240-volt appliances and shifted them from 3-wire wires and receptacles into 4-wire strings and receptacles.
The code applies only to houses constructed after 1996; nonetheless, you might have run into an instance where you’re confronted with attempting to hook up a 4-prong range cord into the house’s 3-prong receptacle or vice versa.
The distinction is that in elderly appliance installations, the legally-installed 3-wire cable consisted of wiring, which has been configured using two hot wires and one neutral wire.
The brand new 4-prong construction provides that the 4th grounding conductor, which has been lacking from the 3-wire configuration.
Picking the Ideal Dryer Outlet for Your House
So you moved into a new residence, along your dryer plug doesn’t match the receptacle. Either your dryer cable has too many or too few prongs to match. This matter is ordinary and does not mean that your house has Bad Wiring, and it surely does not mean that you have to obtain a new dryer.
Homes built before the mid 90’s only essential 3-prong receptacles, but in 1996 the National Electric Code (NEC) falsified all-new house wiring usage as a neutral for Dryer and Range electric circuits.
Like most code changes, the shift has been created to improve security by restricting the possibility of electric shock, and that’s why your brand new house includes a 4 prong dryer socket, and your dryer cable will not match.
Why Was a Change Needed?
The possibility of electric shock was beginning to become increasingly more of a problem with the growth of digital screens and components using 120v for their performance through the drier circuit was 240v with no neutral.
This condition gets harmful since the voltage is cycling back and onto a ground wire rather than the essential neutral wire. Since the metallic framework is secured to the incoming ground cable, there has been a possibility to become amazed by stray voltage when touching the drier.
Individuals are far more in danger if they’re barefoot while utilizing the dryer. What’s the gap between 120v & 240v?
Truth: The word 220-volt circuit isn’t right in the USA. We use 240 volts as a benchmark, although most appliances run off 240v or 220v. A dryer with 5000 watts when provided with a 240v pulls 20.83 amps as a dryer employing the same 5000 watts when provided with 220v pulls 22.73 amps. The 240v system is a lot more efficient.
What Was the Option?
The clear solution was to bring a neutral cable to the 120-volt components that could operate securely without being used as a neutral route. Modern houses are wired with 10-3 NM Cable (Romex) and four-prong dryer receptacles installed.
This wiring system safety includes all voltage back into the critical electric panel, in which the neutral and ground are secured together. Any flaws that happen use the grounding route to the Earth Rods or Grounding System and voltage travels to the Earth rather than energizing the drier’s metallic framework.
Truth: Your drier circuit ought to be provided from a two rod 30amp Breaker. When it’s more than 30 amps, then the incorrect Breaker has been installed. If your panel does not have breakers and uses a cartridge and screw-in fuse, it’s time to consider a Panel Upgrade. Telephone an Electrical Contractor in Greenville to get a test.

What Can You Do?
Adding a 4 Prong Dryer Cord will be the advised course of action. With the average price of a brand new cordless compared to 25 along with the setup between the elimination of a cover plate, 3 conclusion screws, and one-floor connection, this qualifies as a DIY project with lots of YouTube Videos supplying information.
Even though this is a medium DIY project for those who are the least bit uneasy or uncertain, please consider employing an Electrician at Greenville for help. Always turn off the electricity and confirm the electricity is off before working on any electrical system.
