Design Sequence
Scope, load, cable, protect, test
ScopeLoadCableProtectionTesting
Connected Load vs Maximum Demand
Connected load
- Total installed load
- Before diversity adjustment
Maximum demand
- Expected highest operating load
- Uses diversity assumptions
Do not size blindly
Design and Approval Flow
- Electrical fitting scope→Confirm activity context(Activity 453014)
- Technical staff route→Check qualification evidence(Degree or diploma route)
- New design begins→Check governing documents(Code plus current circulars)
- Loads are known→Build load schedule(Assess maximum demand)
- Cable is selected→Apply correction factors(Check current and voltage drop)
- Protection is selected→Coordinate protection(Check fault protection)
- Drawings are ready→Control revisions(Use current approved set)
- Connection is needed→Follow DEWA process(Enrolment is separate)
Load Assessment
- Connected load
- Total installed load
- Maximum demand
- Expected highest operating load
- Diversity
- Not all loads simultaneous
- Load balance
- Distribute phase loads
- Power factor
- Active to apparent power
- Load schedule
- Document design assumptions
RCD vs Circuit Breaker
RCD
- Residual current protection
- Detects imbalance current
Circuit breaker
- Overcurrent protection
- Interrupts overload or fault
Select protection by hazard
Cable Selection
- Design current
- Expected circuit current
- Current capacity
- Cable thermal capability
- Voltage drop
- Voltage loss along cable
- Ambient correction
- Account for temperature
- Grouping correction
- Account for bundled cables
- Installation method
- Affects cable rating
Earthing and Bonding
- Earthing
- Fault-current safety path
- Protective earth
- Equipment protective conductor
- Bonding
- Connect exposed conductive parts
- Earth fault
- Fault involving earth path
- Fault loop
- Fault-current return path
- Earth continuity
- Verify protective path
Protective Devices
- Circuit breaker
- Overcurrent protection device
- Fuse
- Sacrificial overcurrent protection
- RCD
- Residual current protection
- Isolation
- Separate equipment from supply
- Discrimination
- Coordinate protection operation
- Fault rating
- Interrupt prospective fault current
Wiring and Equipment
- Distribution board
- Circuit distribution enclosure
- Cable containment
- Support and protect cables
- Ingress protection
- Environmental enclosure rating
- Segregation
- Separate incompatible circuits
- Accessible isolation
- Permit safe equipment isolation
- Workmanship
- Neat orderly installation
Safe Isolation
Identify, isolate, lock, prove, work
IdentifyIsolateLockout tagoutProve deadWork
Inspection vs Testing
Inspection
- Visual compliance examination
- Checks installation condition
Testing
- Measured verification checks
- Records electrical results
Use both verification stages
Verification and Safety Flow
- Work is planned→Assess hazards(Define work controls)
- Circuit work starts→Identify energy sources(Check all supplies)
- Isolation is required→Isolate equipment(Use site procedure)
- Isolation is applied→Lock and tag(Prevent reconnection)
- Before touching conductors→Prove dead(Use approved test method)
- Installation is complete→Inspect installation(Check visual compliance)
- Inspection is complete→Perform tests(Record measured results)
- Results are acceptable→Keep certificates(Maintain project records)
Approval Documents
- Single-line diagram
- System connection summary
- Load schedule
- Circuit load summary
- Distribution schedule
- Board circuit details
- Electrical drawings
- Design submission information
- Revision control
- Track approved drawing changes
- Authority approval
- Follow current submission process
Isolation vs Prove Dead
Isolation
- Separate equipment from supply
- Control reconnection risk
Prove dead
- Verify de-energized conductors
- Use approved test method
Isolation needs verification
Inspection and Testing
- Inspection
- Visual compliance examination
- Testing
- Measured verification checks
- Continuity test
- Confirm conductive path
- Insulation test
- Check insulation condition
- Polarity test
- Verify conductor connections
- Test certificate
- Record verification results
Safe Work Controls
- Risk assessment
- Identify work hazards
- Permit to work
- Authorise controlled work
- Lockout tagout
- Control energy isolation
- Prove dead
- Verify de-energized conductors
- PPE
- Use task-appropriate protection
- Current circular
- Check latest authority direction
Common Traps
Qualification versus generic licence
Use technical staff context ≠ Do not invent electrician exam
Municipality versus DEWA service
DEQ concerns technical staff ≠ DEWA enrolment concerns contractors
Published versus assumed logistics
Question count not published ≠ Do not repeat third-party figures
Study topic versus exam weight
Use reference areas ≠ Weights are not published
Cable size versus load
Check correction factors ≠ Check voltage drop too
Isolation versus safety proof
Isolate and lock equipment ≠ Prove conductors are dead
Last Minute
- 1.Confirm activity 453014
- 2.Use technical staff context
