APPLIED SAFETY LAB 06 / 16
Zero is a reading.
Evidence is a process.
Inspect the setup. Read the ratings. Question the result. A virtual electrical testing studio from Jenkins Academy of Applied Technology.

Teaching assumptions, primary sources & limits
E-06, Q-06, M-06, R-06, T-06, P-06 and F-06 are fictional. No real product, CAT certification, hazard assessment, isolation or safe work condition is established. The simulated 480Y/277 V context is a label/record exercise; no physical voltage exists in this page. P-06’s expected 24 V AC response is stipulated for this fictional tester, not a real proving-unit specification or calibration.
The six AC comparisons apply only to this supplied fixture with no neutral/DC circuit. Actual tests must cover the parts and sources to which people may be exposed, including backfeed/induced voltage and other energy. An unexpected indication remains unresolved; no repair, discharge, grounding or energized diagnostic technique is taught.
General-industry federal OSHA scope is used. Construction, electric power generation/transmission/distribution, local rules, employer procedures and exact manufacturer instructions require their own review. CAT is a measurement category plus voltage rating, not a PPE selection. This lab supplies no arc-flash calculations, distances, energized-work permission or qualification.

This lab stipulates before/after function checks for every case. OSHA 1910.333(b)(2)(iv)(B) expressly adds the immediate before/after equipment check for circuits over 600 V nominal; this 480 V case rule is not a claim that OSHA’s threshold is different. A function response does not calibrate a meter or verify its whole range.
Source review: October 27, 2026. Original Academy schematics; no vendor artwork or manual pages copied. AI-assisted development. Independent technical, accessibility, device and learning validation remain pending. No OSHA, Government or manufacturer endorsement.
