QUESTION 8.15 What is the preferred nominal voltage for portable hand lamps for general use on construction sites? A. 110 volts B. 150 volts C. 230 volts D. 400 volts Right Answer: A 110 volt reduced low voltage systems are strongly preferred for the supply to such equipment. QUESTION 8.16 What is the preferred nominal voltage for portable hand tools on construction sites? A. 12 volts B. 24 volts C. 110 volts D. 230 volts Right Answer: C 110 volt reduced low voltage systems are strongly preferred for the supply to such equipment. QUESTION 8.17 What is the preferred nominal voltage for local lighting up to 2 kW on construction sites? A. 55 volts B. 110 volts C. 400 volts D. 230 volts Right Answer: B 110 volt reduced low voltage systems are strongly preferred for the supply to such equipment.

A. 50 volts B. 110 volts C. 230 volts D. 400 volts Right Answer: A Where the environment is damp, or restricting and conductive, the magnitude of any electric shock will be higher 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 electrically separated from earth. QUESTION 8.19 If you only have a mains voltage (230 V) hand drill and you want to use it on a construction site which only has yellow (110 V) socket-outlets, what should you do? A. Use a transformer to boost the voltage B. Cut the plug off and fit a yellow one instead C. Obtain a 110 V drill or a cordless one for the work D. Make up an extension cable with a yellow plug on one end and a standard socket on the other end Right Answer: C Electrical equipment must not be modified or operated at voltages other than their design voltage. QUESTION 8.20 What is most commonly used to reduce 230 volts to 110 volts on site? A. Residual current device B. Transformer C. Circuit breaker D. Step-down generator Right Answer: B A transformer, usually coloured yellow, will transform 230 volts (mains voltage) down to a relatively safe 110 volts. QUESTION 8.21 When using an extension cable reel, which of the following statements is correct? A. Leave as much as possible coiled up on the reel B. Uncoil it fully every time C. Do not exceed the reeled or unreeled rating as appropriate D. Only uncoil what you need Right Answer: C The rating of a partially unreeled extension cable is much lower than when fully unreeled. Overheating of the cable will occur if the rating is exceeded. Care should also be taken to prevent extension cables becoming a tripping hazard. QUESTION 8.22 If an extension cable is to be run across a site road, what action should you take? A. Throw wooden boards over it B. Place a rubber protection ramp over it and put up a sign stating Ramp Ahead C. Don't do anything to protect the cable D.
