This is rather inexpensive as it does not require a re-wiring of your laundry room. The screw terminals, in most cases, have directions on which wire is supposed to be connected.

The connections on the appliance are easy to maneuver, and you do not need a professional to do the replacement. You may continue using your 3-slot dryer but replace the dryer cord.

In conclusion, although the 3-slot system has been phased out, authorities realize the futility of trying to upgrade every residence’s system or buy a new dryer altogether. Due to the return path for the power not consumed being separate, the possibility of shock is eliminated. On the other hand, the 4-slot dryer plugs have two hot wires, the ground, and the neutral wire. This opens up the possibility of the metal frame becoming energized, which could cause an electric shock. Though the 3-slot plugs are effective in power provision on dryers, the neutral and ground wires are connected. The latter has two live slots, a neutral, and grounding slot. This is designed to fit dryers with 3-slot plugs. The main difference is that in the former, it is fitted with two live slots and one ground slot. The Difference Between the 3-Slot & 4-Slot Dryer For homes being built today or converting from gas to electric, it is now mandatory that 4-slot dryers be installed.

For residences built in the mid-1990s, it was a requirement by the National Electric Code to install 3-slot outlet. Many people have had the dilemma of trying to convert the 3-slot dryer into the 4-slot one and vice versa.

If you install any wire or grounds, get a book on wiring installation and learn how to do it properly and legally, so the wire is not damaged and any electrician who touches it won't want to tear it out and redo.The 3-slot dryer outlet is currently being replaced by the 4-slot as is required by law. You can remove the insulation, but you must remove all of it - hard to do in jacketed Romex. You cannot buy or hack a 240V-only dryer (which takes NEMA 6-30) and replace your plug and re-designate the white wire to be ground instead. You might be able to bond to a water heater's ground, but ask a code expert before you do that. not to 120V outlets, those have 12 or 14 gauge ground wires - too thin. Route however you can, to either the service panel inside on a ground lug, or to a ground screw inside a box in all-metal conduit that is continuous back to the service panel. It must be at least 10 AWG - single wire will do, but the wire must be bare, green or greeen/yellow, and re-marking another color is not allowed. Replace the NEMA 10-30 outlet with a 14-30 by running a separate ground wire.
Ground is optional in metallic conduit, the conduit is a legit ground path. If you prefer, you could run metallic or non-metallic conduit and use single-wire THWN wire (preferably stranded for easy pulling). If you're not comfortable going inside the service panel, leave about 4 feet of excess length and call an electrician to make the connections. Follow the old wire and replace if feasible.
For a dryer circuit, Romex 10/3 is the right stuff, it sells for less than $1/foot. The hazard is, if the neutral fails, it will energize the chassis of the dryer at 120V and will electrocute users, and has. The rationale is there are a lot of old NEMA 10-30's out there, and trouble is unlikely since dryers and stoves are rarely moved and plugs are rarely unplugged. If you have a 3-wire cable with NEMA 10-30, you have several options, and the rest of this post is about that.įor dryers and stoves specifically, Code allows you to "cheat": bond ground to the neutral wire. I went to Home Depot to replace the 4 prong plug with a 3 to match the outlet. If you have a 4-wire cable with NEMA 14-30, you're all set. White wire when changing from 4 prong to 3 on dryer Ask Question Asked 7 years, 1 month ago Modified 1 year, 2 months ago Viewed 46k times 2 I recently moved into a home with a 3 prong outlet for my 4 prong Kenmore dryer. The neutral goes to the silver screw in the center, and the two hots go to the brass screws on either side. Getting power to the machine is the easy part.
