Transcript of "City & guilds electroctechnical technology - installation & buildings"

  1. 1. Installation (Buildings and Structures) CERTIFICATE IN ELECTROTECHNICAL TECHNOLOGY
  2. 2. The statutory regulations that set standards which will reduce the risk of electric shock, burns and fire due to the use of electrical systems are <ul><li>a. the Electricity at Work Regulations b. the IEE Wiring Regulations c. the Personal Protective Equipment Regulations d. the Health and Safety at Work Act. </li></ul>
  3. 3. Specific guidance is given to the selection of cable sizes, isolation and switching, and inspection and testing for electrical installations in <ul><li>a. the Health and Safety at Work Act b. the Electricity at Work Regulations c. the Electricity Supply Regulations d. the IEE Wiring Regulations. </li></ul>
  4. 4. In high rise buildings lightning conductors must be bonded to the <ul><li>a. building girder work b. water and gas supplies c. the installation earth d. earthing rod. </li></ul>
  5. 5. BSEN numbers on electrical equipment signifies compliance with <ul><li>a. International standards b. European standards c. English standards d. Insulation standards. </li></ul>
  6. 6. Exploded views in manufactures manuals are generally used to show <ul><li>a. complex components with many parts b. large machine parts c. wiring diagrams of machines d. machines having few parts. </li></ul>
  7. 7. An electrical contractor drawing up a list of materials and equipment required to complete an installation will need access to <ul><li>a. delivery records b. drawings and specifications c. circuit diagrams d. day work sheets. </li></ul>
  8. 8. A drawing measuring 2m x 1m representing a site measuring 2km x 1km will be drawn to a scale of <ul><li>a. 1 : 500 b. 1 : 1000 c. 1000 : 1 d. 500 : 1 </li></ul>
  9. 9. To check the ongoing progress of a contract, the contracts manager would use <ul><li>a. work sheets and time sheets b. operation and data sheets c. delivery records and reports d. operation sheets and memorandum. </li></ul>
  10. 10. Circuits used to measure and control temperature, air flow, and humidity in a building are called <ul><li>a. emergency management circuits b. environmental control circuits c. power control circuits d. security control circuits. </li></ul>
  11. 11. A wiring system allowing easy replacement and addition of cables is <ul><li>a. PVC conduit b. steel wire armoured cable c. mineral insulated cable d. metallic cable trunking. </li></ul>
  12. 12. In an installation where appearance is the most important consideration, the most likely choice of a wiring system will be <ul><li>a. ladder racking b. mineral insulated cable c. armoured cable d. cable tray. </li></ul>
  13. 13. When calculations show that the voltage drop between the supply terminals and a load will exceed 4% of the supply voltage the action to be taken is to <ul><li>a. limit the time the load is connected b. increase the supply voltage using a transformer c. increase the size of the cable supplying the load d. connect the load at off peak times only. </li></ul>
  14. 14. To comply with IEE Wiring Regulations the voltage drop on a three phase 400v circuit should not exceed <ul><li>a. 5v b. 10v c. 20v d. 30v </li></ul>
  15. 15. Copper cored data communication cables are made up of pairs of conductors twisted along their length in order to <ul><li>a. reduce electrical interference b. add strength to the cable c. reduce overall cable size d. increase the cable current rating. </li></ul>
  16. 16. A component designed to disconnect a supply under full load conditions is <ul><li>a. a fuse b. an isolator c. a detector d. a switch </li></ul>
  17. 17. In situations where there is a risk of an explosion due to the presence of fumes and gases electrical switches and control equipment must be <ul><li>a. remotely controlled b. mounted in flameproof enclosures c. placed outside the danger zone d. connected to a low voltage supply. </li></ul>
  18. 18. The TT system of earthing is usually used in <ul><li>a. rural areas b. urban areas c. domestic installations d. industrial installations. </li></ul>
  19. 19. An earthing system that can only be used in special circumstances and uses a combined neutral and earth conductor in the supply and the installation is the <ul><li>a. T T system b. T N-S system c. T N-C-S system d. T N-C system. </li></ul>
  20. 20. Isolators used to isolate electrical supplies are designed to operate under <ul><li>a. full load conditions b. no-load conditions c. overload conditions d. short circuit conditions. </li></ul>
