Pancyprian Electrical Engineering III (Practical) study plan

Select the correct cable type, current-carrying capacity and derating factors for at least six realistic installation scenarios (grouping, ambient temperature, thermal insulation, buried, in conduit).

Calculate voltage drop for each of those six circuits and reject any design that exceeds the permitted drop for lighting and power.

List and justify the safe isolation procedure step by step, including proving the tester before and after the test and locking off.

Identify the correct containment system (trunking, conduit, tray, basket, clip direct) for given building types and state two installation rules for each.

State the fire-stopping and support/spacing requirements that apply to cable routes through walls, floors and ceilings.

Explain how automatic disconnection of supply works for TN-S, TN-C-S and TT systems and calculate maximum earth fault loop impedance for each using the device's disconnection time.

Select the correct protective device type (MCB type B/C/D, RCBO, RCD, fuse) for given load characteristics including motors, transformers and equipment with high leakage current.

Distinguish between earthing and protective bonding, list what must be main bonded, and state the sizing rule for main protective bonding and circuit protective conductors.

Describe the additional protection provided by 30 mA RCDs and state where they are required, including socket outlets, mobile equipment outdoors and locations containing a bath or shower.

Apply the shock-protection measures (basic, fault and additional) to three worked examples and identify which measure is missing in each.

Sequence the full initial verification of a new installation from safe isolation through dead tests to live tests, and state the purpose of each test in one sentence.

Perform and record continuity of protective conductors, ring final circuit continuity, insulation resistance, polarity and earth electrode resistance, interpreting sample results against expected values.

Carry out and interpret live tests: earth fault loop impedance, prospective fault current, RCD operating time and ramp test, and functional testing of devices.

Complete the schedule of test results and schedule of inspections entries for a small domestic installation without omitting mandatory fields.

Identify the documentation set required on completion (certificate, schedules, notices, and where a minor works certificate is appropriate) and state who may sign each.

Map the key regulatory duties for electrical installation work onto practical jobsite actions: design responsibility, competence, verification before energising, and record keeping.

Explain the role of the wiring regulations standard and how to look up a specific requirement by part and chapter rather than by memory.

State the requirements for consumer unit selection and location, including IP rating, non-combustible enclosure considerations, spare ways and accessibility.

Describe the function and selection of main switch, RCD/RCBO arrangement, SPD where fitted, and the labelling and notice requirements for a distribution board.

Explain the legal and practical consequences of working outside competence or without notification where notification is required.

Diagnose at least eight fault scenarios (tripping RCD, tripping MCB, high Zs, low insulation resistance, open circuit protective conductor, reverse polarity, borrowed neutral, intermittent fault) using a logical test sequence.

Apply Ohm's law, power relationships and series/parallel resistance to calculate expected test values before measuring, and use the discrepancy to locate faults.

Calculate cable size from load current, derating and voltage drop for a given design current, and verify the protective device coordinates with the cable's capacity.

Explain the effect of a borrowed neutral and a shared RCD on fault finding, and describe how to isolate the faulty circuit without disturbing healthy ones.

Describe safe repair practice: making good, correct jointing methods, torque of terminations, and re-testing after repair.

Plan a full small installation from load assessment through circuit division, board layout, cable routes and containment, producing a materials list.

Install containment and cable to a professional standard: bending, support spacing, segregation of band I and band II circuits, and protection against external influences.

Terminate and dress a consumer unit with correct conductor identification, torque-checked terminations, and no exposed basic insulation.

Verify that the installed work matches the design before testing, and record any deviations with justification.

Apply workmanship standards to labelling, schedules, warning notices and as-installed documentation.

Demonstrate the full safe isolation routine under timed conditions, including proving the tester, locking off, and issuing a caution notice.

Explain the correct use and limitations of test instruments: multifunction tester, insulation tester, loop tester, RCD tester, and proving units.

Interpret borderline and anomalous test results and decide whether to investigate, re-test or record as a departure.

Identify the personal protective equipment and site controls required for live testing and for work in occupied premises.

Describe the procedure for handing over an installation: verification, certification, client instruction and records.

Complete a full mock practical task end to end: design, install, inspect, test, certify and hand over within the allotted time.

Resolve calculation questions under time pressure, covering load current, cable sizing, voltage drop, Zs and disconnection time.

Answer regulation-lookup questions quickly by locating the relevant part and chapter of the standard.

Review all weak areas from weeks 1 to 7 and close at least three specific gaps with targeted practice.

Self-assess the mock task against workmanship, safety and documentation criteria and write an improvement list.
