PHILIPPINE ELECTRICAL CODE. REVIEWER Electrical Plans and Specifications. Requirements for Electrical Installations. Here is a downloadable pdf file of the Philippine Electrical Code. Chapter 1. General ARTICLE — INTRODUCTION Purpose. Hack De Cash Love Ritmo resourceone.info the descent part 3 movie free downloadinstmank bad boy telugu movie free download torrent karthik.
Neutral Conductor — The conductor connector to the neutral point of a system that is intended to carry current under normal conditions. New Technologies and Requirements Art The second new definition expounds references to Republic Act RA which is the current national engineering law. This way, the nation engineering law remains relevant should Republic Act be superseded.
Service Protective Device defines the new equipment addition to Code provisions related to service equipment. Also, three important new sections have been added: 1 Section 1. Arc-Flash Hazard Analysis has been added to the requirements under Section 1. Chapter 2 — Wiring and Protection Important revisions include: 1 Deletion of requirement for arc-fault circuit-interrupter due to non-availability for Philippine specifications, 2 In addition to Code requirements on multi-occupancy buildings, their application to site developments -where group s of single detached buildings are constructed — have been included, 3 Clarified and expanded provisions on Service Protective Device when installed ahead of Service Equipment, and 4 clarified provisions on grouping of Disconnecting Means.
Chapter 3 — Wiring Methods and Materials Rationalized ampacity tables of conductors — copper and aluminum — for three conductors in raceway and in free air up to volts, Tables 3.
Ampacities are based on current densities of the cross-sectional areas of the conductors. Article 3. This limitation has been removed from PEC1 and is required only maximum of 48 if the panel board is protected on its supply side by two sets of circuit breakers or two sets of fuses. Fixed Electric Space-heating Equipment has been expanded while Fixed Resistance and Electrode Industrial Process heating equipment has also been added.
Chapter 8 — Communication Systems Added new Article 8.
Chapter 9 — Tables A new Table This type of cable, type FCC consists of three or more flat conductors placed edge to edge, separated and enclosed within an insulating assembly. This used for general purpose, appliance branch circuits and for individual branch circuits specifically on hard, smooth, continuous floor surfaces, etc.
Medium Voltage Cables. MV cable is a single or multiconductor solid dielectric insulated cable rated 2, volts or higher and is used for power systems up to 35, volts.
The MV cables are of different types and characteristics. The common types of raceways in household wiring are the a conduits, b connectors, and c others. According to the type of materials used, conduit maybe classified as either metallic such as steel pipes or nonmetallic such as PVC, and the like.
According to its make, conduits maybe classified as: rigid metal, flexible metal, rigid nonmetal and flexible nonmetal. A connector is also called a splicing sleeve. An outlet is a point in the wiring system at which current is taken to supply utilization equipment. The kinds of outlets are: convenience outlet or attachment cap, lighting outlet, and receptacle outlet. A convenience outlet or attachment cap is a device which by insertion in a receptacle, establishes connection between the conductor of the flexible cord and the conductors connected permanently to the receptacle.
A lighting outlet is an outlet intended for direct connection of a lampholder, a lighting fixture, or a pendant cord terminating in a lampholder. A receptacle outlet is an outlet where one or more receptacles are installed.
It may be used only in dry locations. Some manufactures no longer make the ordinary Type T, instead produce Type TW, which is identical in appearance, but may be used in wet or dry locations.
Also available is Type THW, is similar to Type TW but withstand a greater degree of heat, and consequently has a higher ampacity rating in the larger sizes. Nylon has exceptional insulating qualities and great mechanical strength, all of which results in a wire which is smaller in diameter than ordinary Types T, TW, TW of corresponding size. It may be used in dry or wet locations. While at present, it is an expensive wire, it would be no surprise if in due course of time, this one single type will replace all the many types and subtypes of Type T or R now recognized by the Code.
Over the copper is a layer of rubber, the thickness of which depends on the size of the wire. Then follows an outer fabric braid which is saturated with moisture-and-fire-resistant compounds; if it is set on fire with a blowtorch, the flame dies out when the torch is removed.
The most ordinary kind is Type RHW, which may be used for dry or wet locations. Types RH and RHH have insulation which withstands more heat and therefore have a higher ampacity in the larger size.

They may be used only in dry locations. A location classified as dry may be temporarily subject to dampness or wetness, as in the case of a building under construction.
WET LOCATION Installations underground or in concrete slabs or masonry in direct contact with the earth, and location subject to saturation with water or other liquids, such as vehicle washing areas, and locations exposed to weather and unprotected.
Class I Locations. Class I locations are those in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitible mixtures. A Class I, Division 1 location is a location: I in which igntible concentrations of flammable gases or vapors can exist under normal operating conditions; or ii in which ignitible concentrations of such gas vapors may exist frequently because of repair or maintenance operations or because of leakage; or iii in which breakdown or faulty operation of equipment or processes might release ignitible concentrations of flammable gases or vapors, and might also cause simultaneous failure of electric equipment.
A Class I, Division 2 location is a location: I in which volatile flammable liquids or flammable gases are handled, processes, or used, but in which the liquids, vapors, or gases will normally be confines within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems, or in case of abnormal operation of equipment; or ii in which ignitible concentrations of gases or vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment; iii that is adjacent to Class I, Division 1 location, and to which ignitible concentrations of gases or vapors might occasionally be communicated unless such communication is prevented by adequate positive ventilation from a source of clean air, and effective safeguards against ventilation failure are provided.
Class II Locations.
Class II locations are those that are hazardous because of the presence of combustible dust. A class II, Division 1 location is a location: I in which combustible dust is in the air normal operating conditions in quantities sufficient to produce explosive or ignitible mixtures; or ii where mechanical failure or abnormal operation of machinery or equipment might cause such explosive or ignitible mixtures to be produced, and might also provide a source of ignition through simultaneous failure of electric equipment, operation devices, or from other causes; or iii in which combustible dusts of an electrically conductive nature may be present in hazardous quantities.
A Class II, Division 2 location is a location where combustible dust is not normally in the air in quantities sufficient to produce explosive or ignitible mixtures, and dust accumulations are normally insufficient to interfere with the normal operation of electrical equipment or other apparatus, but combustible dust may be in suspension in the air as a result of infrequent malfunctioning of handling or processing equipment and where combustible dust accumulations on, in, or in the vicinity of the electrical equipment may be sufficient to interfere with the safe dissipation of heat from electrical equipment or may be ignitible by abnormal operation or failure of electrical equipment.
Class III Locations. Class III locations are those that are hazardous because of the presence of easily combustible fibers or flyings, but in which such fibers or flyings are not likely to be in suspension in the air in quantities sufficient to produce ignitible mixtures. A Class III, Divisions 1 location is a location in which easily ignitible fibers or materials producing combustible flyings are handled, manufactured, or used.Steven Hung.
Class II Locations. Class II Locations. Some manufactures no longer make the ordinary Type T, instead produce Type TW, which is identical in appearance, but may be used in wet or dry locations. Power and Control Tray Cable. A Class II, Division 2 location is a location where combustible dust is not normally in the air in quantities sufficient to produce explosive or ignitible mixtures, and dust accumulations are normally insufficient to interfere with the normal operation of electrical equipment or other apparatus, but combustible dust may be in suspension in the air as a result of infrequent malfunctioning of handling or processing equipment and where combustible dust accumulations on, in, or in the vicinity of the electrical equipment may be sufficient to interfere with the safe dissipation of heat from electrical equipment or may be ignitible by abnormal operation or failure of electrical equipment.
Class III locations are those that are hazardous because of the presence of easily combustible fibers or flyings, but in which such fibers or flyings are not likely to be in suspension in the air in quantities sufficient to produce ignitible mixtures. A Class III, Division 2 location is a location in which easily ignitible fibers are stored or handled.
