1. Equipment at the consumer intake point
   40 min · 1 practice tasks · quiz
   The equipment where the electricity supply enters a building - service cable, meter, main switch, fuse/breaker and consumer unit - their functions, the correct sequence of connection and why it matters, and the consumer earthing point.
2. The KPLC service line
   40 min · 1 practice tasks · quiz
   How Kenya Power brings electricity to the building: overhead or underground service cable, 240 V single-phase, and where supplier equipment ends.
3. The supplier cut-out
   40 min · 1 practice tasks · quiz
   The sealed KPLC cut-out fuse at the intake: what it protects, why consumers must not open it, and how it differs from the house main switch.
4. The energy meter
   40 min · 1 practice tasks · quiz
   How the intake meter records kWh for billing, the difference between postpaid and prepaid token meters in Kenya, and why the meter sits early in the sequence.
5. The main isolation switch
   40 min · 1 practice tasks · quiz
   The consumer main switch: how it isolates the whole installation, why it is double-pole, and why it is not the same as a fuse.
6. Main fuse and circuit breaker
   40 min · 1 practice tasks · quiz
   How the main fuse or MCB protects the installation against overload and fault current, and how a fuse differs from a resettable breaker.
7. The consumer unit
   40 min · 1 practice tasks · quiz
   How the consumer unit (distribution board) splits the supply into final circuits, each with its own MCB, and where an RCD fits.
8. Functions of the control equipment
   40 min · 1 practice tasks · quiz
   Pulling the intake together: how meter, main switch, protection and consumer unit each control power, and why earthing sits under all of them.
9. Installing intake equipment in sequence
   40 min · 1 practice tasks · quiz
   The correct installation order from KPLC service to consumer unit and earth, why that sequence is fixed, and how to practise it on a mock board.
10. The consumer earthing point
    40 min · 1 practice tasks · quiz
    Why the installation must have an earth electrode and main earth terminal: the fault path that trips protection and stops a live case shocking someone.
11. Installing an earth electrode
    40 min · 1 practice tasks · quiz
    How to prepare a consumer earthing point: excavate or drive the electrode, clamp the conductor, protect the joint, connect to the MET, and test.
12. Why intake equipment must follow the rules
    40 min · 1 practice tasks · quiz
    Why KPLC seals, the wiring code and earthing are not optional: unmetered taps, missing isolation and missing earth are how people get shocked, burned or prosecuted.
