Solidly Grounded

The term “solidly grounded” was contained in 230.95, but it was relocated to Article 100 because it’s used in at least eleven articles.
Grounded, Solidly.The intentional electrical connection of one system terminal to ground.
Author’s Comment: In reality, solidly grounded means the bonding of the system to the metal case of the derived system in accordance with 250.30(A)(1). Figure 100-4

  • Mike, If I'm not mistaken you have always instructed that the only ground wire on the XO terminal of the seperately derived system (Transformer) is the MBJ. In the picture on this Online Training letter shows the Ground conductor, the MBJ and the equipment grounding conductor. The way I was taught and the way I instruct and inspect is the only conductors on the XO terminal are the Neutral to the panel and the MBJ to a terminal block solidly secured to the case of the Transformer. Please correct me if I am wrong.
