Students complete hands-on laboratory exercises assembling and testing basic circuits containing these components, developing the diagnostic skills needed to assess electronic control boards in real-world electrical maintenance scenarios.
Safety is not optional in the electrical industry — it is the foundation upon which every professional decision must rest. This critical module ensures that students develop a comprehensive understanding of the regulations, procedures, and behaviours that protect electricians, their colleagues, clients, and the public from the potentially fatal hazards of electrical work.
Students study the Occupational Safety and Health Administration (OSHA) standards as they apply to electrical work, gaining a clear understanding of employer and employee obligations. The module covers Personal Protective Equipment (PPE) requirements in detail — from insulated gloves and arc flash-rated garments to safety footwear and eye protection — and students learn to select the correct PPE for each specific task and voltage level.
Lockout/Tagout (LOTO) procedures receive significant attention, as the ability to safely isolate electrical energy before working on equipment is a fundamental competency for any electrical professional. Students also study hazard identification, risk assessment methodologies, and emergency response procedures — including electrical burn treatment, CPR, and the correct use of Class C fire extinguishers.
Federal and regional electrical safety regulations and compliance requirements.
Correct personal protective equipment for every task and exposure level.
Authorised isolation of electrical energy before maintenance or repair work.

The modern electrical industry relies increasingly on digital tools for design, documentation, project management, and client communication. This module ensures that students are proficient with the essential computer skills and software applications they will encounter in professional practice, giving them a competitive advantage over technicians who lack digital literacy.
Students begin with a review of computer fundamentals — file management, professional communication, and spreadsheet use for job costing and scheduling. The module then progresses to industry-specific design software, with an emphasis on creating clear, professional electrical layout drawings that communicate installation requirements to clients, inspectors, and co-workers.
File management, professional email, spreadsheets, and digital documentation for electrical contractors.
Industry-standard drafting software used to create precise electrical layout drawings and single-line diagrams.
Rapid creation of electrical schematics, wiring diagrams, and floor plan overlays for proposals and permit submissions.
End-to-end practice creating complete electrical layouts from brief to final drawing — ready for client presentation.
The quality of cable terminations is one of the most reliable indicators of an electrician's skill and professionalism. Poorly terminated cables are a leading cause of electrical faults, fires, and failures — and every employer and inspector will judge a technician's work first by the quality of their terminations. This module develops the hands-on precision skills required to produce consistently safe, reliable cable connections across a range of conductor types and termination methods.
Students gain extensive practice in cable identification, measurement, stripping, and crimping across single-core, multicore, armoured, and flexible cable types. The critical importance of the Earth Continuity Conductor (ECC) is emphasised throughout, with students learning how a continuous, low-resistance earth path is the last line of defence in any electrical installation against electric shock and equipment damage.
Each student completes a series of graded termination exercises assessed for quality, consistency, and compliance with manufacturer and code requirements. Continuity testing of completed terminations reinforces the direct connection between workmanship and measurable electrical performance.
PVC twin-and-earth, SWA, flex, and single-core conductors — identification, selection, and handling.

The ability to read, interpret, and create electrical floor plans is a critical professional competency that separates qualified electricians from unskilled labourers. This module develops students' spatial reasoning, technical drawing literacy, and planning skills — enabling them to work confidently from architectural drawings, produce clear electrical layout plans, and communicate installation designs to clients and colleagues alike.
Students begin by mastering the standard electrical symbols used in Caribbean, British, and American drawing conventions — outlets, switches, luminaires, distribution boards, cable routes, and protection devices. They then practise overlaying electrical layouts onto architectural floor plans, determining the most efficient cable routing strategies while complying with code-mandated clearances and installation requirements.
The module extends into elevation drawings, enabling students to plan the precise positioning of outlets, switches, and panels on wall elevations — an essential skill for kitchens, bathrooms, and commercial fit-outs where exact heights and positioning affect both function and compliance. Students also learn to annotate drawings with cable sizes, circuit references, and protection ratings in preparation for permit submissions and client presentations.
