Finally, the central cooking range is in place, but how do you get electricity to it? How can you safely connect wiring to a gas line? This article will cover some basic safety requirements and provide tips on how to wire an electric stove.
The standard safety requirements for a new electric stove installation are:
– A dedicated 20 amp circuit.
– A double-pole, switch on the hot leg of the circuit.
– Grounding to a metal junction box.
– An equipment ground wire from the junction box to the neutral bar in a panel box. If you have aluminum wiring in your house this may be omitted, but it is still a good idea if you have copper conductors. This can prevent some serious damage or fire that could result from connecting an ungrounded stove to aluminum wiring which provides no grounding at all.
This information will provide safety and understanding when hooking up an electric stove and provide wiring diagrams with explanations of these items in more detail below:
– Circuit Breaker – This is the first component of an electrical circuit. It is designed to cause the circuit to trip if there are too many amps flowing through it, which will prevent an overload situation from damaging wiring or components in your home. This type of protection is required by code on all new circuits.
– Disconnect Box – A disconnect box with a double pole switch must be installed near the stove at least 18″ away from any other outlets or junction boxes. This allows for switching between power sources through the disconnect box without risking arcing or shock when disconnecting or connecting either device.
– Junction Box/Outlet Box – All outlets and junction boxes must be metal and grounded to the home’s electrical system through grounding wires. This prevents shock, fire, and damage to appliances due to ungrounded devices. It also allows for easy connection of equipment ground wires should you need them at a later date.
– Ceiling Junction Box – A ceiling junction box must be installed in the ceiling where your electric stove will be located to provide support for all hanging hardware. Electrical Codes often prohibit the use of screws to hang stoves over outlets or switches because of heat concerns which can cause fires if contact is made with something flammable like towels or curtains touching an overheated screw head. This junction box will allow you safely secure your oven without compromising safety requirements.
– Ceiling Ties or Hangers – All ceiling junction boxes must be securely attached to a structural beam in the attic or a joist using ties or hangers. This prevents the box from dropping when it is disconnected and prevents damage due to falling.
Installing Instructions for how to wire a new stove:
Before you can install your stove, you will need to install a disconnect switch and outlet box. You should be able to find pre-fabricated boxes made specifically for hooking up electric stoves in most hardware stores. These outlets are equipped with 220v compatible plugs on the end of them so that they can be easily removed without twisting the wires together.
They also have buttons on them for easy access to disconnecting power from your stove, which is an added safety feature that is required if you are installing a gas line into an electric stove or hooking up more than one circuit using multiple switches.
Step 1 – Installing the Disconnect Box
Once you have installed your disconnect box, you can begin wiring. You will want to start with running 2 hot wires (typically black) from the breaker panel to the switch. It is important to note that 220v wall outlets conduct power on both sides of the outlet due to their design. This means that when wiring your stove, you must have a total of 4 hot wires going to the switch. The neutral and ground will be wired to the outlet box which has a built-in grounding screw or bus bar in it.
Step 2 – Installing the Ceiling Junction Box
A ceiling junction box should be installed near your stove or oven and securely attached to a beam in the attic or joist. Once it is installed, you can wire both hot wires from the outlet box into the switch and any neutrals/grounds that will be leading to different components of your stove such as a pilot light. Remember to leave a few inches of wire on the switch side to give yourself room to work.
Step 3 – Installing the Outlet Box
Once you have wired your outlet box, you can begin attaching wires for each component on your stove that has its own dedicated circuit. Remember that these circuits are hooked up in parallel so they will both be hot regardless of whether one or both elements are turned on. Using an electrical tester, you will need to check the resistance between each terminal and the ground screw in the outlet box to ensure that there is not a short circuit.
Step 4 – Installing On/Off Switches for Induction Cooktops
On/Off switches should be installed for your induction cooktop. These are typically built into the stove or oven already but using two separate switches simply makes it easier to control each side of the burner when you are cooking. Keep this in mind when setting up your circuit breaker panel because if you have more than one circuit running through a switch, turning off the breaker will turn both circuits off.
Step 5 – Installing a Pilot Light System Outlet
To add a pilot light system to your stove, you will need to install a separate outlet box for the pilot light and run 12/2 wire from this box into your ceiling junction box where the rest of the wires from your oven are connected.
At this point, you can turn your system back on and test it out to be sure everything is running properly, but do not turn your oven or induction cooktop back on just yet. First, we need to locate the pilot light connector in the ceiling junction box so that we can install a jumper wire from it to our pilot lightbox.
Step 6 – Installing a Jumper Wire
You need to locate the white wire connected to the oven or stove’s gas valve in your ceiling junction box. From there, you will want to cut off this connector and strip both sides of the wire before attaching them to each side of a jumper wire that is long enough to reach from the ceiling junction box into your new pilot light outlet.
Once you have attached both wires, simply push them into the jumper wire and complete the connection by screwing on a wire nut before securing it back in place in your ceiling junction box.
Step 7 – Installing the New Oven/Stove
Now that everything is wired up, you can attach all of the components back to your oven or stove and plug it in to see if you did everything correctly. If it comes on then great! You did an awesome job.
If however, it doesn’t come on, there are two possibilities. The first would be a blown fuse in your main breaker panel – if the circuit isn’t showing any power running through it, this could be what happened.
The second possibility would be that you have wired something incorrectly – If none of the lights are coming on either at the switch or out in the ceiling junction box then this is probably the case here. Recheck all of your wirings against these instructions one last time before calling in an electrician.
