Wiring Systems and Installation Practice & Electrical Principles and Circuit Theory
Map the wiring-system domain objectives to a one-page checklist and rate your current confidence from 1 to 5 on each objective
Calculate voltage drop, current-carrying capacity and cable size selection for three domestic final circuits using tabulated values
Sketch a radial and a ring final circuit layout from memory, labelling protective devices, cable sizes and points served
Set up a personal formula sheet covering Ohm's law, power, series/parallel networks and voltage drop, then solve ten mixed practice problems with it
Your checkpoint
A worked solutions portfolio of ten circuit calculations plus a labelled hand-drawn radial and ring circuit sketch, both dated and reviewed for errors
Wiring Systems and Installation Practice & Electrical Principles and Circuit Theory
Explain the selection criteria for conduit, trunking, tray and armoured cable in industrial versus domestic settings
Apply the correct rules for bending radii, support spacing and separation of power and data cabling to three installation scenarios
Describe the sequence of operations for first fix and second fix on a commercial lighting installation
Solve fifteen mixed problems on series/parallel resistance, AC impedance and power factor correction
Your checkpoint
A 600-word installation method statement for a small workshop rewire, covering cable routing, supports, bending radii and fix sequence
Electrical Principles and Circuit Theory & Electrical Materials, Tools and Test Instruments
Derive and apply relationships between RMS, peak and average values for sinusoidal waveforms
Interpret nameplate and datasheet data for a multimeter, insulation resistance tester and clamp meter, stating each instrument's measurement limits and safety category
Select appropriate cable insulation and conductor material for hot, wet and mechanically stressed environments with written justification
Demonstrate correct use of a continuity tester and insulation resistance tester in a described test scenario, stating expected readings
Your checkpoint
An instrument selection and test-procedure sheet matching five given measurement tasks to specific instruments, ranges and expected pass values
Protection, Earthing and Fault Diagnosis & Electrical Materials, Tools and Test Instruments
Explain the operation of MCBs, RCDs, RCBOs and fuses, and select the correct device rating and breaking capacity for four given faults
Calculate earth fault loop impedance and verify disconnection times against the relevant limits for TN-S, TN-C-S and TT systems
Describe protective earthing arrangements, main bonding and supplementary bonding requirements for a bathroom and a workshop
Diagnose five described fault symptoms systematically using a half-split method and record the reasoning chain
Your checkpoint
A fault-diagnosis log of five case studies, each with measured values, a stated disconnection-time check and a justified remedy
Milestones
Week 2: You can complete a voltage drop and cable selection calculation for an unfamiliar circuit in under ten minutes without notes
Week 4: You score at least 75 percent on a self-made 30-question mixed test covering domains 2, 3, 4 and 6, and can explain every wrong answer in writing
