Lockout/Tagout (LOTO) & Procedures (Topic 4) in Module 1 – Solar-PV-NABCEP-Associate (BG)

Lockout/Tagout (LOTO) & Procedures

LOTO is a set of procedures to control hazardous energy during maintenance or servicing. For PV, the goal is to prevent unexpected energization and ensure everyone on the crew understands the state of the system.

Practical reminders

  • Identify energy sources (AC, DC, stored energy in capacitors/batteries).
  • Communicate: who applied a lock/tag and why.
  • Verify: don’t assume.

LOTO details vary by employer and site rules, but the exam typically tests the concept: control the energy, label it clearly, and verify before touching conductors/equipment.
