Hello everyone:

Got at new electric cooktop with the standard red, black, white and green wires coming out of it. .

Home wire: Bare (ground), pure black, black with red stripe, black with red and white stripes.

The pure black and the black with red stripe have 110v when tested. If these match with the red and black appliance wires, what's the deal with the black with red and white stripes wire? :confused:

Any ideas would be greatly appreciated! Thank you!

Home:
1. Bare
2. Black (110)
3. Black with red stripe (110)
4. Black with red and white stripe.

Stove:
1. red
2. black
3. green
4. white

I would check at panel where the black and white with the red stripe, Neutral hopefully, may be taped white.
Black to black,
Black/red to red,
Green to bare,
And white to wire from neutral bar, hopefully,
Black with the red and white stripe.

Never seen this before, might be another country, but in some respects it makes sense.

Bare is easy and it's ground
Black is usually one side of a 240
Black with red makes sense that it is US red. For other countries, it may mean black.

The red/black stripe is the return for red and the return for black or neutral.

So, this is how I think the wires make sense.

Some people consider California to be a different country!

I think you are both right but I was thrown by the striping on the wire.

Because of economics, the NEC does not require larger sized wires to be manufactured in colors. I don't have my code book on hand, but I think the cut off is No. 6. Think of the added expense if manufacturers had to stock, and contractors had to use different colors of 500 MCM!)
On commercial jobs with large service andfeeder conductors, the electrician marks the black wires with colored electrical tape in every termination box.
I have also seen USE and triplex cable with all black wires, and a painted red or white strip to designate the red and white wires.
As others have posted, in the US the solid black and black w/red stripes are the hots, and the black w/ white stripe is the neutral.
