How to Wire a 120/240

Freestanding vs. Drop-In Ranges . An outlet receptacle is usually required only for free-standing upright ranges. Drop-in cooktops or wall ovens are usually hardwired, with the circuit wiring connected directly into the appliance connection panel, without the benefit of a plug-in cord and receptacle. The following instructions, then, are normally used only for freestanding upright range/oven ...

Remove the 4-Wire Range Cord and install the replacement 3-Wire Range Cord. Next where the wires are connected to the electric range you will need to re-install the Bonding Jumper which goes between the Grounded Screw and the Neutral Terminal as shown in the 3-WIRE HOOK UP wiring diagram below.

Wiring Diagram for a Stove Plug. Please keep in mind, this is for a 4 wire cord and the outlet for a stove/oven. This is very easy to do but yes it can seem very intimidating. You just came home with the new stove your wife has been looking forward to. You go and pull the old stove out and to your surprise, you find the stove was hard wired.

Wiring a 20-Amp 240-Volt Appliance Receptacle. This outlet is commonly used for a heavy load such as a large air conditioner. The outlet should be wired to a dedicated 20-amp/240-volt circuit breaker in the service panel using 12|2 awg cable.. With this wiring, both the black and white wires are used to carry 120 volts each and the white wire is wrapped with electrical tape to label it hot.

Wiring a new 220 outlet is a project that someone who has experience working with electricity can do safely by working carefully and following the proper precautions. However, working on your circuit breaker box and electrical system can lead to serious injury or death if you don’t know what you’re doing, so hire an electrician if you don’t feel comfortable wiring the outlet yourself.

Use the NEMA plug chart below to identify a configuration by pin array or designation. NEMA designations are based on a two part code where the numbers before the dash represent voltage and wires and the numbers after the dash represent amperage. For example, the "5" in the common 5-15 represents 3-Wire 125V and the "15" represents 15 amp.

Connect the red and black wires to the brass terminal screws inside the plug, the white wire to the chrome screw and the bare wire to the green screw. It's standard 220-volt wiring. If you need help, you can use any four-wire, 220-volt wiring diagram for reference.

Precaution: Identify the main circuit of the panel, turn it OFF and Tag it with a Note before working with the wiring or installing the 240 volt wiring and circuit breaker for the kitchen range. Notice: Installing an additional 240 volt range circuit should be done according to local and national electrical codes with a permit and be inspected.

Range Circuit . An electric range generally needs a dedicated 240/250-volt, 50-amp circuit. That means that you'll need to install a 6/3 NM cable (or #6 THHN wire in a conduit) to feed the range. If it's a gas range, however, it will only require only a 120/125-volt receptacle to power the range controls and vent hood.

Provide power to a new outlet that will supply 220 to 240 volts for use by an electric range or other appliance such as a dryer. The steps below describe electrical service panels, wire colors and procedures commonly followed in the U.S.A. and required by the National Electrical Code.
