Formula & key-relationship bank from verified solutions
Typical fundamental phase RMS: 180° mode ≈0.4502Vdc; 120° mode ≈0.3898Vdc. Thus 180° gives the higher fundamental component.Require NPSH_available > NPSH_required with design margin.Fire-life-safety services require reliable emergency supply and protected routing.Whole-building compliance can use prescriptive or performance approaches depending on code version/state adoption.Touch voltage and disconnection time depend on earthing and protective-device coordination.PAT sets specific energy-consumption targets and enables trading of Energy Saving Certificates subject to scheme rules.
Use these as revision triggers and open the linked PYQ before applying a formula numerically; variable definitions and assumptions belong to the exact solved question.
Core ideas repeatedly reinforced by the solved corpus
- In 180° mode three devices conduct at a time; in 120° mode only two conduct and one phase is disconnected during each step. Waveform/fundamental comparison confirms 1. The 60° same-leg off interval of 120° mode contradicts 2, and…

Exam tips already validated in SRO solutions
- 120° mode: two switches ON, one phase floating. 180° mode: three switches ON.
- Cavitation questions: compare available and required NPSH.
- Treat fire lift as a life-safety system, not an ordinary passenger lift.
- Commercial-building scope is the key exam distinction.
- Low earth resistance is desirable—not high resistance.
Common mistakes to avoid
- Assuming a balanced load forces the floating neutral to stay at zero under a non-sinusoidal switching waveform.
- Priming is unnecessary only for self-priming arrangements or when suction is already flooded.
- Do not omit emergency power/identification requirements.
- Do not apply ECBC indiscriminately to all residential buildings.
- Never state that high earth resistance improves safety.

How to revise this authority page efficiently
- Solve before reading:answer a mapped PYQ first.
- Read the exact explanation:verify the correct principle, formula, distractor logic and common mistake on that question page.
- Move one level in the graph:use the closest concept/sub-topic/topic link rather than opening unrelated content.
- Reattempt:solve another verified PYQ from this hub and check whether the same error repeats.
