Which Wire Is Which – Here Is The Key
Electrical Question: I am replacing lights under the shelf on my desk with fluorescent fixtures which are wired in parallel, as I have learned how to do here.
- I want to use the electrical cord that I cut off from the old light to power the new fixtures, since it is already attached to the desk and shelf.
- How can I determine which wire in the cord to attach to the white wire in the fixtures?
- And which to attach to the black?
