Part of an electric circuit extending beyond last circuit breaker or fuse. _ Earthing_______2. Connecting earth terminals to electrodes installed solidly in the mass of earth. _Circuit Breaker__3. A manually or automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. _As a Science___4. The amounts of illumination needed and certain aspects of the quality of light have been quantified. _Plumbing_____5. The art and technique of installing pipes, fixtures, and other apparatuses in buildings for bringing in the supply of liquids, substances and/or ingredients and removing them. _Day lighting___6. Complete process of designing buildings to utilize natural light to its fullest. _Accent Iighting__7. Directional light intended to emphasize a particular object or draw attention to a pan of the field of view. _Corporation stop_8. Control of the water service, and a shut-off when service is disconnected __70-79_________9. Color rendering index for most office, retail, school, medical, and other work and recreational spaces. __Lumen_____8. Measurement of light emitted by a lamp. _Convenience Outlet _10. Device that acts as a convenient source of electrical energy for current consuming appliances. _Nonmetallic Conduits or PVC Conduits 11. conduits are used in underground installations.

Circuit protective device that automatically blows and cuts the current when overload or short circuit happens. _Water Meter____13. Device used to measure the amount of water that passes through the water service. _ Electrical Conduits/Pipes_14. Materials used as the passage of wires for protection and insulation. _Flat Cord_______13. Duplex stranded wire used for temporary wiring installation and commonly used in extension cord assembly. _Electrical Metallic Tubing (EMT)_15. Conduits that are easy to bend, cut and form, also known as thin wall conduit. _Natural Surface Water16. Obtained from ponds, lakes and rivers _Range Boiler__17. Small hot water tank (30-60 cm in diameter; not more than 180cm in length) _Globe Valve__ 18. Controls the flow of water with a movable spindle. _Slop sink_____19. Where janitor clean and leave their mops. _Fixture Branch_20. The water supply pipe between the fixture supply pipe and the waterdistributing pipe. PART II. ENUMERATION. (1 pt. each) 1-3 Effect of acquiring low cost equipment 1. High Energy Cost 2. Higher Maintenance Cost 3. Shorter Life 4-6 Classification of Branch 1. General purpose branch circuit 2.
