The course includes compliance with TB 118A and will teach and assess people to work safely and appropriately without putting themselves or others at risk of electric shocks or other danger. The course includes basic understanding of electricity, use of voltage meters and confirmation that circuits and cables are dead and safe on both single and 3 phase installations.
