In the context of apprentices, what is indicated by "2nd step"?

The phrase "2nd step" in the context of apprentices typically indicates that the apprentice has reached a level of training where they are now eligible to work with certain voltages. This implies that they have progressed beyond just observation and have acquired a foundational understanding of the necessary skills and safety measures related to handling electrical systems. This stage often signifies that the apprentice is starting to engage more actively in their training, which may include supervised work on systems that operate under specific voltage levels.

Completing training or being able to work independently would generally correspond to higher levels or stages of the apprenticeship, and merely observing does not align with the progression suggested by the term "2nd step." Therefore, eligibility to work with specific voltages is a more appropriate interpretation of what this term represents in the context of apprenticeships, as it indicates a transitional phase in their development.
