We have a duplex receptacle in a gem box recessed in a wall ( . 120v. 20 amp ). In a 6' greenfield whip dropped down
The wall coming. From box in ceiling to gem box in the wall
We have a black #12 for the hot. A. Black #12 with white tape on it to identify it to be the neutral and a green for the
Ground. Will the black with white tape on it for identification
To be neutral pass the electrical inspection? National code.
Thanks!!

We have a 120v duplex receptacle in a drop ceiling (acoustical) . This is used for a 120v to 24 v transformer
This intern feeds a time clock on the wall 6' a.f.f the 24v runs down wall to the clock. Does this meet national code if receptacle is above the ceiling??
Thanks!!

The actual Code text for when a white wire is used as a hot reads:

...shall be permanently reidentified to indicate its use by painting or other effective means at its terminations and at each location where the conductor is visible and accessible.

Black tape is not considered permanent, but the ruling will be up to the inspector.

Cords of appliances, and I believe a clock with a 24 volt power pack that serves the clock applies here, are not to pass through structure, such as a suspended ceiling.

Again, up to the final decision of the inspector.

I say no to both.

With respect to the Black conductor with the white tape on it to identify it as a Neutral conductor.

This is a flat out code violation. Neutral conductors smaller than 6 AWG must be either white, gray or any color other than green with three vertical white stripes to be considered as Neutral.

Please reference NEC, Chapter 2, Article 200.6(A)

Good catch Don I read it completely backwards.
