The core electrical-testing division of the AGL Testing & Commissioning Manual. Division 02 verifies the electrical integrity, continuity, insulation, resistance, polarity, voltage, current, power, circuit connections, transformer circuits, connectors, control circuits, and auxiliary supplies of the installed AGL system — before any functional or system-level commissioning begins.
Sequence: Prepare → Isolate → Verify Safe → Test → Record → Evaluate → Accept/Reject → Report. Test methods, test voltages, permissible limits, discharge requirements, and acceptance values are always taken from the applicable project specification, approved test procedure, equipment manufacturer requirements, and applicable standards — this division defines the testing scope, not the numerical acceptance limits.
Every topic in this division follows the same underlying sequence, whatever the circuit or equipment under test — and every result is carried through to a formal evaluation and acceptance decision, never accepted on the strength of a recorded number alone.
Division 02 is worked as a staged sequence rather than a single pass — each group below builds on the one before it, and the division closes only once evaluation and acceptance are complete.
| Group | What It Confirms |
|---|---|
| A — Insulation & Continuity | Cable and equipment insulation is intact, and the intended electrical path exists without an unintended open circuit |
| B — Earthing | The installed earthing system, earth electrodes, and protective bonding paths meet resistance and continuity requirements |
| C — Polarity & Resistance | Connections are correctly oriented, and circuit/cable resistance is consistent with design expectations |
| D — Electrical Measurements | Required supply voltage, current, power, and phase configuration are present and correct at specified test points |
| E — Cable & Termination Testing | Installed cables, joints, and terminations are electrically and mechanically sound |
| F — Circuit & Equipment Verification | Primary and secondary circuits, transformers, and connectors are electrically verified before energization |
| G — Control & Auxiliary | Control circuits and auxiliary supplies are electrically sound ahead of functional testing |
| H — Evaluation, Acceptance & Reporting | Every result is evaluated against an approved criterion, formally accepted or rejected, and traceable to a test report |
Two requirement groups should be closed out before the Division 02 team starts working through the topic list.
Grouped by test focus, in the order the division is normally worked — click any topic to expand its verification checks and acceptance criteria.
Acceptance Criteria: measured insulation resistance meets the value specified in the project specification/approved test procedure, with the circuit safely discharged and restored only after confirming safe conditions.
Acceptance Criteria: result is recorded as continuity satisfactory for every test point; any "not satisfactory" result is investigated and corrected before proceeding.
Acceptance Criteria: measured earth resistance meets the project acceptance criterion. Earth resistance and earth continuity are also revisited under the dedicated Earthing & Bonding Testing division.
Acceptance Criteria: protective earth and bonding paths are confirmed electrically continuous at every typical point, with no broken or loose bonding conductor outstanding.
Acceptance Criteria: measured cable resistance is consistent with calculated/design resistance and manufacturer data, with any significant deviation investigated and closed out.
Acceptance Criteria: measured voltage at every specified test point is within the nominal/design range, recorded with instrument ID and operating condition.
Acceptance Criteria: measured current is consistent with expected current and stable across operating conditions. Detailed CCR output-current and regulation testing is addressed subsequently under CCR Testing & Commissioning.
Acceptance Criteria: measured power, and power factor/frequency where applicable, is consistent with the applicable design and equipment requirements.
Acceptance Criteria: phase sequence, identification, and connection are confirmed correct at every applicable AC supply point.
Acceptance Criteria: measured insulation resistance for each installed AGL cable meets the applicable acceptance value, with discharge completed after every test.
Acceptance Criteria: every cable joint present is uniquely identified, tests satisfactory for continuity and insulation, and is mechanically sound and sealed.
Acceptance Criteria: every secondary-side component — transformer secondary, secondary cable, connector, and fixture — is confirmed continuous, correctly connected, and free of open or short circuits.
Acceptance Criteria: the electrical test requirement for each isolation transformer is satisfied here; the dedicated Division 04 — Isolation Transformer Testing & Commissioning provides the full transformer testing and commissioning procedure.
Acceptance Criteria: every connector in the circuit is correctly identified, mated, locked, and continuous; connector testing is later expanded to identification, continuity, contact, mating, locking, sealing, cable-lead, and electrical verification.
Acceptance Criteria: control-circuit electrical integrity is confirmed here; whether the control system actually performs the required operational sequence is verified later under the ALCMS and System Integration divisions.
Acceptance Criteria: every auxiliary and project-specific supply feeding control and supporting equipment is confirmed correct for voltage, continuity, protection, and earthing.
Acceptance Criteria: every electrical test is traceable to a formal test record following the recommended report structure, complete with acceptance sign-off before the division closes.
Division 02 sits between installation readiness and the specialized commissioning divisions — no result proceeds forward without evaluation, and no division closes without acceptance.
Installation readiness verified and energization authorized.
Division 02 confirms insulation, continuity, resistance, polarity, voltage, current, power, and circuit connections.
Division 03 builds on verified electrical integrity for CCR-specific testing.
Division 04 provides the dedicated transformer testing and commissioning procedure.
Division 05 onward proceeds into fixture, runway, taxiway, control, and photometric commissioning.
Every result passes through the evaluation sequence before any PASS is recorded.
Failed or abnormal results are corrected and retested before proceeding.
The Master Electrical Test Report closes the division and hands the system forward.
Quick answers about Division 02 — Electrical Testing in the AGL Testing & Commissioning Manual.
Division 02 of the AGL Testing & Commissioning Manual covers Electrical Testing. It is the core electrical-testing division of the AGL Testing & Commissioning Manual. Division 02 verifies the electrical integrity, continuity, insulation, resistance, polarity, voltage, current, power, circuit connections, transformer circuits, connectors, control circuits, and auxiliary supplies of the installed AGL system — before any functional or system-level commissioning begins. It contains 23 topics (TC-ELE-001 to TC-ELE-023) organised into 8 groups (A–H), each topic with its own verification checks.
