I have an electronic access control license in Texas that permits me to work on Class 1, 2, and 3 power limited, remote control, and signal circuits. At what point am I no longer allowed to legally work on a circuit? ie. I have a 120v 20A circuit wired directly to a transformer that steps down to 24v control wiring. Am I legally allowed to disconnect and then reconnect that 120v wire to replace the power supply?

Hi Ryan, This is a great video, thanks. I have one question about Class 2, in article 725, Table 11(A), and Table 11(B), why is the limit for Class 2 is 8 A and 100 W? What is rational?

But you can't have a door bell transformer in a panel board, correct?

Well, you can have a doorbell transformer in a panelboard's cabinet, but the secondary circuit would violate 725.136.

I squared R (i.e. I^2 R) is electrical power, not "R squared I"

"9V is not enough to kill you" So that's why when I test a 9 V transistor radio battery by touching it to my tongue doesn't kill me! (A little humor need to be inserted in your video as it was getting a little dry)
