4. What is an ELECTRICAL PLAN? It is a type of technical drawing  that delivers visual representation and describes circuits and electrical systems. It consists of symbols and lines that showcase the engineer's electrical design to its clients. BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS Also referred as “Electrical Drawing”  or “ Wiring Diagram” . Composed of Lighting and Power Layouts and other electrical specifications.

5. What is an AUXILIARY PLAN? These are components related with Security Systems, Comfort Systems, Lighting Systems and Information Systems witch are very important to help the main system to perform according the specifications. BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS Provides supplementary or additional help and support to the basic systems of a building Composed of Electronic and Communications systems. PABX – Private Automatic Branch Exchange Also referred as “telephone system”, these are switchboards that connect to several devices.

6. ELECTRICAL NOTES REFERENCE: PHILIPPINE ELECTRICAL CODE (PEC) Parts 1 & 2, 2017 Edition Based from the 2017 National Electrical Code of USA. (NFPA 70, NEC) Regularly revised every three(3) years to reflect the evolution of products, materials, and installation techniques. The primary objective of the code is to establish basic materials quality and electrical works standards for the safe use of electricity for light, heat, power, communications, signaling and for other purposes.

7. LEGEND AND SYMBOLS BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS

8. POWER SERVICE ENTRANCE Also referred to as “service drop” It is where the wires connected to the load side of the meter enter the house or building. BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS

9. KILOWATT HOUR (Kwh) METER These are compact electronic monitoring devices that measure the consumed energy flowing through a circuit such as a standard 120V or 240V BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS

10. ELECTRICAL PANELBOARD Also called, “distribution board”, “breaker panel” or “electric panel”. It is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure. BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS

11. CIRCUIT BREAKER It is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. CIRCUIT HOMERUN A home run is a wire that graphically represents the wiring of a circuit to a central location that acts as the distribution point for the power, typically, a panel.  BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS

12. GROUND ROD / GROUND CLAMP Also known as grounding electrodes. Used to connect the grounding system of electrical systems to earth ground. They are very good conductors of electricity and allow any dangerous electricity to flow to ground, taking the danger away from you and the electrical panel. BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS

13. PULL BOX FOR TELEPHONE AND CATV They are used along with conduit to simplify wiring installation. They provide a way to pull conductors at long distances without placing excessive strain on the wire or insulation. BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS

14. SWITCHES They are used to turn electrical current on or off for nearly any electrical device. BLT - BUILDING TECHNOLOGY II MODULE 09 ELECTRICAL AND AUXILIARY DRAWINGS
