Week Lesson Strand Sub-strand Lesson Learning Outcomes Learning Experiences Key Inquiry Question(s) Learning Resources Assessment Reflection
11 1 Electrical Installation 3.2 Equipment at the Consumer’s Intake Point By the end of the lesson, the learner should be able to:
a> prepare consumer earthing point per regulations;
b> excavate and install earth electrode;
c> show responsibility in grounding safety.		 The learners will be guided to:
i> dig shallow trench (or simulate);
ii> install copper rod with clamp;
iii> connect to main earthing terminal.		 Why is earthing the lifeline of electrical safety? Earth rods, clamps, trench area Earthing installation rubric —
11 2 Electrical Installation 3.2 Equipment at the Consumer’s Intake Point By the end of the lesson, the learner should be able to:
a> measure earth resistance using fall-of-potential method;
b> interpret acceptable vs. high resistance;
c> appreciate testing in safety assurance.		 The learners will be guided to:
i> use earth resistance tester (or simulate);
ii> record readings;
iii> discuss need for multiple rods if high.		 How do we know earthing is good enough? Earth testers, rods Measurement and interpretation rubric —
11 3 Electrical Installation 3.2 Equipment at the Consumer’s Intake Point By the end of the lesson, the learner should be able to:
a> simulate fault current path through earthing;
b> demonstrate how earthing prevents shock;
c> value life-saving design.		 The learners will be guided to:
i> use safe demo circuit with fault;
ii> show current diverted to earth;
iii> contrast with ungrounded danger.		 How does earthing keep you alive during a fault? Demo circuit, safety models Simulation explanation rubric —
11 4 Electrical Installation 3.2 Equipment at the Consumer’s Intake Point By the end of the lesson, the learner should be able to:
a> visit a real intake point (or detailed virtual tour);
b> observe professional installation;
c> show respect during site visit.		 The learners will be guided to:
i> tour school or local building intake;
ii> take notes and photos (if allowed);
iii> write reflection on real-world standards.		 How do classroom lessons translate to real installations? Site visit or VR tour, reflection sheet Visit reflection rubric —
11 5 Electrical Installation 3.2 Equipment at the Consumer’s Intake Point By the end of the lesson, the learner should be able to:
a> design a safe intake point for a rural home;
b> include all components and earthing;
c> apply equity in rural electrification.		 The learners will be guided to:
i> sketch layout for off-grid solar home;
ii> integrate meter, protection, earthing;
iii> present with cost estimate.		 How can we bring safe power to every Kenyan home? Design sheets, component catalogs Rural design rubric —
