What is the ground & neutral wire for a JPK15 GE Oven?


Assuming this is in the USA there are 3 wires normally in a 240 volt circuit. A black, red and white. Sometimes there is a bare ground wire. The white wire and bare ground wire are basically the same.They connect to the same place in the electrical box. The red and black are your power wires. They would connect top the outside connectors and the white and bare wire (if supplied) would connect to the center connector.

Replacing a light fixture


This is much simpler than it sounds, but if you're a total novice you'll need to read it all.

First, make sure power to fixture is off. Best method is to locate circuit breaker or fuse that controls that fixture's power. At minimum shut off the wall switch to it if there is one.

Next, remove the old fixture. Usually there are two screws or decorative nuts holding the base cover (canopy) on. On ceiling pendant fixtures there may be a retaining ring holding up the canopy, unscrew this ring counterclockwise and the canopy will drop over the support chain, exposing the junction box where the wires are connected.

It is critical at this point that the power is off.

Modern house wiring and fixtures are connected with three wires.
Green or bare copper = ground (earth)
White or grey = neutral
Black, Red, Blue or any other solid color other than green, white or grey = power or hot wire (this is the wire that is controlled by a switch.
For simplicity I will call the three: Green, White and Black.

The next step requires you to carefully pull the wires out of the junction box and isolate the black, white and green wire connections from each other. Make sure the connectors (wire nuts) for each connection are accessible.

Warning: With old or over heated wiring, take extra care not to crack or disturb the insulation(wire covering) on any of the wires. If insulation is crumbling away exposing bare wire, stop and call an electrician! Do not turn the power back on until he has repaired those damaged wires, they could start a fire.

Isolate the connection between the black house wire and black fixture wire. Remove this wire nut. At this point I usually use an electrical tester to double check that the power is off by touching one side to the newly exposed black connection and any grounded metal part nearby.
(Note: some multiple switched (three way) circuits may use a white wire as a power wire. If the black fixture wire is connected to a white house wire, mark that white house wire with black electrical tape for future identification.)
Once you are positive there is no power at the fixture junction box remove the connectors from the white and green wires.

Detach the old fixture and it's mounting bracket.

Re-attach the new fixture using bracket and new connectors that are usually provided. Some brackets have a green ground screw. Wrap the bare ground wire clockwise around that screw and tighten it down leaving enough remaining ground wire to attach to the fixture ground.

If the wires to the new fixtures do not have a 1/2 inch of exposed bare wire at the ends (stripped) you must do so. I use a wire stripping tool but you can do it with a sharp knife being careful not to nick the metal wire.
Once the wire tips are stripped, hold the tips of each color pair together side by side, slip the wire nut over them and twist clockwise until snug. (White to white, black to black etc.)
Take care that the new wire nuts are secure at each connection. Do not over tighten them but insure that they are correctly attached by gently tugging on each wire. When completed the black and white connections should have no exposed bare wire showing.
The Green (bare copper) wire is there for safety and never carries current, hence exposed wire is not an issue on ground wires.

Assemble and attach the new fixture according to instructions in the box.

Pendant ceiling fixtures usually require additional assembly steps including adjusting chain height, looping wires through the chain and slipping retaining nut and canopy over chain prior to connecting. Always follow directions that come with the fixtures.

When in doubt, call a professional. Electricity is dangerous.

I think I can help you but i am a bit confused with the panel box and the junction box. If you want to reply explain the circuit in a bit more detail from the switchboard where the fuse is to the back of the oven. It would also be a good idea to have a voltmeter or test lamps handy. Does the double pole breaker do the Active and Neutral or is it 2 phases going through the breaker. Did the wiring used to be for a full range and now there is only the new oven in its place.

15265 In-Wall Digital Timer - I am replacing an Aube with this new timer. Timer is to operate a wall plug (outdoor soffit). Timer is inside. The old switch had 3 wires - only two were connected (I think...

Ah, the usual how to connect 4 wires to the old 'was-3-wire and now-2-wire' problem.

I tested and wired these timers.
Aube timer has internal rechargeable battery, and therefore does not need another wire to run internal clock.
GE timer has extra wire to run internal electronic clock, just like alarm clock is plugged in.

Heres what to do in simple format
1) Timer-green-wire connects to bare ground wire.
2) Old timer has 2 wires. Take both wires and connect them to timer-black-wire and timer-red-wire. Choose either one for now.
3) In back of electric box are white wires twisted together and covered with wire nut. Connect timer-white to these wires. This action will complete circuit to internal clock.
4) If electric box does not have white wires described above, then connect timer-white to bare ground. This works because bare ground and white neutral both connect to neutral busbar inside breaker box.
5) Turn on electricity, push in timer door for manual override. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires.
If light does not come on, double check that outdoor bulb is good, and that breaker not tripped.
Timer can also be reset in event of short. Reversing red and black wires will not short timer.

I just bought a jp328sfss and need to know how to wire it to the breaker panel the way it is wired now it only heats water to 120 degrees F the handyman that hooked it up said there was no way to wire it...


It sounds like you better be careful for starters. I also suggest your handyman sticks to painting. In older homes a 208/240 circuit onlt had three wires. New construction and remodeling requires a four wire system. Per code, a black wire is 120VAC, and a red wire is 120VAC. In a 240VAC circuit they would be called L-1 and L-2 respectively. In order to provide 240VAC they must be on seperate phases. The bare wire in your bundle is the ground wire and is at the same potential as neutral, or the white wire in current four wire systems. If you know how to use an electrical test meter, you should show 120VAC from black to bare copper, 120VAC from red to bare copper, and 240VAC from black to red. If this is not the case, I strongly suggest you have an electrician come in and take care of it in your breaker panel. *****Electricity is nothing to fool around with if you are not absolutely sure you know what you are doing. A loose connection, a wrong connection can result in fire, serious injury or death. It's worth a service call to a licensed electrician or qualified appliance service technician to give you peace of mind, and years of safe use of your new cooktop.

Wall Oven - Connecting three wires to four


as long as the incoming power comes from the main power panel, then black to black/red to white these will be your 2 hot phases/the other white and 2 bare wires will be the neutral connection

Oven says: ''supply open neutral'' no buttons work what to do?


That means the range is not connected properly, or the power supply to it is not correct. The range needs the neutral (along with one of the hot leads) to supply the 120 volt portion of the voltage required to operate the control. On built in ovens, the red and black are connected to the two hot supply wires, the white to neutral, and the green or bare copper wire to ground. If your supply only has three incomming wires (older homes) then the green (or bare copper wire) and white are both connected to the neutral.

How to wire a jenn air cooktop JEC9530ADB


the new cooktops and ovens now have a 4th wire used for separating the ground and neutral. some new homes and remodeled homes have a 4th wire run from the circuit panel to the unit.
you dont have this but it is ok to just hook up the white and green/ground wires together. then red to red and black to black. it will work properly and thats all you have to do.
