Question 8.18 What is the recommended maximum voltage for portable hand lamps when working in confined or damp locations? A: 50 volts B: 110 volts C: 230 volts D: 400 volts
Right Answer: A Where the environment is damp, or restricting andconductive, the magnitude of any electric shock will behigher than under normal conditions. Hand lamps in such locations should therefore be supplied from a SELV(separated extra-low voltage) system, i.e. having a maximum voltage of 50 volts and which is electricallyseparated from earth.
