Hi Bob. Welcome to Just
You are correct.
Black to black, white to red, and bare to green.
I thought red was a hot wire, not so in this situation? Why did LG use a red wire instead of white?
What's probably throwing you off is that the white from the wall is a hot, not a neutral. That's a little unusual, but not overly. It's not terribly uncommon to see 240 volt circuits that are run with only black, white, and ground have the white as a hot. That means that circuit doesn't need a neutral.
The red from the cooktop is a hot, as is the white from the wall.
OK, so I can turn on the power and all will be well?
Yes, it should be all set.
Still, funny they don't provide any information on this situation and only the instructions show matched colors.
I understand. I actually haven't connected one for a few years now, as I work in maintenance at a hospital now. But I know for sure the connections I advised are correct.
Thanks very much for your kind assistance.
You are most welcome. Is there anything else I can do for you?
That was my only item to check on. Thanks.
My pleasure. Take care.
