4B prep with the same serious plant-first structure.
The 4B lane is built to support plant operations, controls, safety, maintenance, and system reasoning inside a clean power engineer workflow.

Current path
Power Engineer 4B
This page is already aligned with the same premium trade-page structure as the rest of CodeSafe, so the 4B lane grows into a proper first-class path instead of a stub.
Why this page matters
Make 4B look ready to scale, not like an afterthought.
Even before the bank finishes filling out, the 4B trade surface should already feel aligned with the stronger flagship pages on the site.
Class-specific path
The 4B lane is positioned to support plant equipment review, safe operating decisions, controls understanding, and stronger system reasoning.
Built for future depth
Power engineer content grows under one family, so Class 4B can sit inside a stronger long-term path as more CodeSafe power engineer coverage expands.
Exam-style flow
As the question bank fills out, the page structure is already ready for practice sets, mocks, and the same polished review flow used across live trade lanes.
Topic coverage
Positioned for plant systems, controls, safety, and operating logic.
The 4B path is staged to support a real power engineer study lane instead of forcing learners into unrelated trade flows.
