Inspection and Testing
Inspection and testing can feel difficult at first, but it becomes clearer when each test is broken down into purpose, method, result and safety reason.
Safe Isolation
Learn how to prove dead correctly using approved test equipment and safe working procedures.
Continuity Testing
Understand CPC continuity, R1 + R2, ring final continuity and why low resistance matters.
Insulation Resistance
Study how insulation resistance testing checks the condition of cables and connected circuits.
Polarity, Zs and RCD
Revise polarity, earth fault loop impedance and RCD testing for safe disconnection of supply.
Special Topic Areas
Extra learning areas to support modern electrical training.
Electrical Science
Ohm’s law, power, resistance, capacitance, magnetism, AC theory and calculations explained clearly.
Renewable Energy
