ProSpray 20 BASIC PRINCIPLES ELECTRICALLY INSTRUCTED PERSON In order to carry out work on electrical systems and equipment, a person must at least have training as an electrically instructed person. However, an electrically instructed person is not authorised to autonomously set up, modify or repair electrical systems and equipment.
ProSpray 20 Contents of BGV A3: The test as per BGV A3 is divided into a visual and a metrological test. Visual inspection: - Protective conductors (protection class I ) - Insulating parts - Housing - Connecting cables - Typeplate...
ProSpray 20 Earthing and short-circuiting After ensuring safe isolation from the supply, the conductors and earthing must be connected together with short-circuit-proof earthing and shorting jumpers. With this measure, the upstream overcurrent protective devices trigger and the system is imme- diately isolated in the event of inadvertent restoration of power.
