This covers wiring of socket outlets, switches, lighting fixtures, and GFCI/AFCI devices to code. Students will apply correct cable termination methods for safe, durable connections.

Lesson 1 • GFCI, AFCI, and Surge Protection

This covers ground fault, arc fault, and surge protective devices required in modern installations. Students will identify required locations and verify correct device operation after installation.

Lesson 2 • Earthing Electrode Systems

This covers earth rods, concrete-encased electrodes, water pipes, and structural steel as electrodes. Proper electrode installation ensures effective fault dissipation to earth.

Lesson 3 • Fuses and Circuit Breakers

This explains fuse types, circuit breaker operation, and interrupting ratings for overcurrent protection. Correct device selection protects conductors and equipment under fault conditions.

Lesson 4 • Equipment Earthing and Equipotential Bonding

This addresses equipment earthing conductors, bonding jumpers, and bonding of metallic systems. Correct bonding eliminates voltage differences that cause shock and equipment damage.

Lesson 1 • Utility Service Types and Configurations

This identifies overhead and underground service types, voltage configurations, and utility requirements. Understanding service types guides correct equipment selection and installation planning.

Lesson 2 • Load Centre Sizing and Service Calculations

This teaches service load calculations using standard and optional methods to size service equipment. Accurate calculations prevent undersized services and costly future upgrades.
