Generated explanation

The illustration shows an open electrical distribution panel with a main breaker, branch-circuit breakers, bus bars, neutral bus bars, and a grounding terminal. Service conductors enter at the upper right, and cables labeled for 240 volt and 120 volt circuits enter through the right side. At the upper branch-circuit entry, a dimension indicates that cable sheathing should extend no more than 1 inch into the panel. The lower cable has a long loop of outer sheathing inside the enclosure, highlighted with a red prohibition symbol and an annotation identifying the excessive extension as improper.
