Course. 3.0.1.2 Limitations. In no case shall this point of attachment be less than 3 000 mm above finished grade. (a) General. Service raceways shall be equipped with a raintight service head at the point of connection to service-drop conductors. The main feed cable has come into the attic through the weather head. To prevent the entrance of moisture, service-entrance conductors shall be connected to the service-drop conductors either (1) below the level of the service head or (2) below the level of the termination of the service-entrance cable sheath. The neutral leads should be white not red. If a switch and fuse combination is used, the fuses employed shall be capable of interrupting any current higher than the interrupting capacity of the switch during a time that the ground-fault protective system will not cause the switch to open. 2: Where two to six service disconnecting means in separate enclosures are grouped at one location and supply separate loads from one service drop or lateral in multiple-occupancy building or group of single detached buildings owned/managed/operated by a person or entity, one set of service-entrance conductors shall be permitted to supply each or several such service equipment enclosures. The maximum capacity of the plug in breakers is 100 amps, so if you need a panel box with a larger capacity, buy one designed for bolt-on breakers. with 4.30.4.2, 4.30.5.2, and 4.30.5.3 shall be permitted. We are far from being panel box experts, but we will share our experiences. In such cases, the service disconnecting means shall be permitted to be electrically operated by a readily accessible, remote-control device. The rating of the service disconnect shall be considered to be the rating of the largest fuse that can be installed or the highest continuous current trip setting for which the actual overcurrent device installed in a circuit breaker is rated or can be adjusted. The best approach may be to cut the original 2-prong plug off of the appliance cord and install a grounded plug, making sure that the polarity is correct. A fuse rated in continuous amperes not to exceed three times the ampacity of the conductor, or a circuit breaker with a trip setting of not more than six times the ampacity of the conductors, shall be considered as providing the required short- circuit protection. While the authors have used good faith and efforts to ensure that the information and instructions contained in this work are accurate, the authors disclaim all responsibility for errors or omissions, including without limitation responsibility for damages resulting from the use of or reliance on this work. Where exposed to the weather, raceways enclosing service-entrance conductors shall be raintight and arranged to drain. FPN No. the all electrical works shall comply in accordance with these plans and specifications. The overcurrent device shall protect all circuits and devices. A 12-2 Romex will have a black (hot) and a white (neutral) wire as well as an unsheathed copper wire for ground. Service-entrance conductors entering or on the exterior of buildings or other structures shall be insulated. Except for table lamps, all lighting is recessed, no ceiling fixtures or chandeliers except in the bathrooms. Fortunately, grounded outlets are readily available and that’s what we used. Panel Box wired using double pole breakers, one pole load, one pole neutral. B. LEGEND AND SYMBOLS. (d) Grounding Connection. This neutral to ground bonding is a must. Our electrical engineer originally proposed a 125 amp panel box for our house. Exception: A grounded conductor shall be permitted to be uninsulated as follows: Service-lateral conductors shall have sufficient ampacity to carry the current for the load as calculated in accordance with Article 2.20 and shall have adequate mechanical strength. At the bottom of each electrical pole is (or should be) a ground rod which is connected to the transformer and to the line serving your house. 2.30.4.1 Number of Service-Entrance Conductor Sets. The GE double pole breakers we used cost P400  each – after negotiation. Exception: Where it is impracticable to locate the service head or gooseneck above the point of attachment, the service head or gooseneck location shall be permitted not farther than 600 mm from the point of attachment. Wiring and Protection/Article 2.25 - Outside Branch Circuits And Feeders, PEC:Philippine Electrical Code 2009 Part 1/Chapter 2. (b) Service Cable Equipped with Raintight Service Head or Gooseneck. We only had one load wire. READ PAPER. Basically, the house is built without much regard to electrical or plumbing runs. The assumption that the two halves of DP breakers can serve as SP breakers proved to be very wrong. Since the panel box only came with a load and neutral buses, we added a ground (earth) bus. Commercial buildings in Iloilo almost always use Panasonic outlets and switches. Wiring and Protection/Article 2.10 - Branch Circuits, PEC:Philippine Electrical Code 2009 Part 1/Chapter 2. Wiring and Protection/Article 2.40 - Overcurrent Protection, PEC:Philippine Electrical Code 2009 Part 1/Chapter 2. We chose plug-in because that’s what we were familiar with in the U.S.  As we will see, that was a mistake. Therefore, we do not recommend bringing breakers from the U.S. This is an expensive option, possibly more expensive than buying new 230v appliances. Mark Anthony Dusal. We took out the link we had installed connecting the two panel box bus bars and bought new double-pole breakers. This was just a photo to show the Meiji receptacle. The quality of grounding of the neutral wire can be uncertain due to improper earthing at the pole or in the residence. Most outlets have only a load wire and a neutral wire. There are 17 electrical standards suppliers, mainly located in Asia. 2.30.4.4 Wiring Methods for 600 Volts, Nominal, or Less. Service conductors installed as open conductors or multiconductor cable without an overall outer jacket shall have a clearance of not less than 900 mm from windows that are designed to be opened, doors, porches, balconies, ladders, stairs, fire escapes, or similar locations. Wiring is in flexible plastic conduit. Normally, utility power flows through the DPDT switch to the panel box. It also allows us to put the switch in a neutral position where no power from either source is flowing to the panel box. Above is a snapshot of a generator switch which uses a separate circuit and breaker for circuits which are energized when the generator is running. Here is when we got into trouble. NFPA 78, Guide on Electrical Inspections. Because the capacity of the generator is limited, less than what’s available from the utility company, we check to see that high consumption circuits (mostly air conditioning) are not on when we start the generator. 3:06 AM. Plug in breaker showing panel box copper bus bars. Wage rates are negotiable and far more reasonable than in your home country. FPN No. Academic year. Below is a plug made with brass-plated steel prongs rather than brass. A 12-3 Romex will have a black (hot), red (hot), white (neutral), and bare copper. We ran a separate #14 AWG ground wire to each outlet. Loads shall be determined in accordance with Article 2.20. From the point of view of the equipment or the power source, the source and return wires are constantly being interchanged. We were happy to tear out and replace the old 6AWG wire which had several splices with heavier cable all connected with crimp connectors. We cut the links on the handles and wired up our panel box. Also indicates the status of the circuit breaker (On or Off/tripped). After the generator is running, we have used one of our air conditioners powered by the generator without a problem. NECA 120-2018 Standard for Installing Armored Cable (Type AC) and Type Metal-Clad (MC) Cable This standard covers the identification, selection and installation of Type AC and Type MC cables, which are used for electrical wiring for residential, commercial and industrial occupancies. Cable overcrowded in conduit can overheat. Installation..... 70–231 III. We have a ground (earth) provided by the homeowner. 2: This added protective equipment at the service equipment may make it necessary to review the overall wiring system for proper selective overcurrent protection coordination. Where individual open conductors enter a building or other structure, they shall enter through roof bushings or through the wall in an upward slant through individual, noncombustible, nonabsorbent insulating tubes. Our theory is that a thin layer of grease from the kitchen went up through the recessed fixtures and coated the wires. Bachelor of science in Electronics and Communication Engineering (BSECE) Uploaded by. This type of panel box is really engineered for use with the 120-240v three wire type of system but can be used with the 230v three wire systems too. copper or 14 mm2 aluminum or copper-clad aluminum. Underground service-lateral conductors shall be protected against damage in accordance with 300.5. Generally, outlets have one wider slot and one narrow slot so that plugs can only be plugged in in one way. Actuator lever – used to manually trip and reset the circuit breaker. The Philippine Distribution Code (PDC) 2017 Edition is the result of several years of technical review, analysis, and coordination work among the members and technical » Learn More If you have two wires you probably have a single 230 volt load wire and a single combined neutral/ground wire. That day the Code became available as a PDF document through the. Most breakers are designed so they can still trip even if the lever is held or locked in the “on” position. A building or other structure served shall be supplied by only one service unless permitted in 2.30.1.2(a) through (d). Our outdoor security lights can also be controlled by this Panasonic timer switch which is wired into our panel box. 120 VAC cannot be supplied by this type of system unless the property owner, at his own expense and with the cooperation of the utility company, installs his own transformer at the utility pole, a transformer having a secondary winding which can supply 120 VAC. Take the information here as hypothesis, not gospel. (c) Performance Testing. Anam is a mid-priced Korean brand which seems to be of very good quality. Exception: Type SE cable shall be permitted to be formed in a gooseneck and taped with a self-sealing weather-resistant thermoplastic. For our purposes let’s call the three wire urban systems as “three wire 120/240V systems” and the two wire systems as “two wire 230V systems”. The ground-fault protection system shall operate to 2.30.7.3 Locked Service Overcurrent Devices. Exception No. One advantage of the rebar ground being in the attic is that it is protected from the corrosion or damage risk outdoor ground rods are prone to. Here’s what we’ve learned. The Panasonic outlets grip the prongs of the plugs so strongly that we have pulled the outlets out of the wall when trying to remove a plug. In the meantime, keep in mind that ordinary circuit breakers are not intended to protect humans from many of the most common types of shock hazards. Power from the generator (when running) comes in at the bottom. would be supplied in the U.S. All small and large appliances sold in the Philippines are designed to use 240 VAC, 60C. The counter staff at these places can be quite knowledgeable. Unlike in the US which uses 110V for standard appliances, the standard voltage level for residential use in the Philippines is 230V according to the PEC. (c) Remote Control. University. Service heads shall have conductors of different potential brought out through separately bushed openings. Calibration screw – allows the manufacturer to precisely adjust the trip current of the device after assembly. ... electrical wiring color code philippines electrical wiring color code standards philippines. Consider, for example, that (depending on the design of the breaker)  a 30 A breaker will take one hour to trip at a current of 40 A. FPN: See 4.8.3.7(a) for service equipment in panelboards, and see 4.30.8.4 for service equipment in motor control centers. The utility feed cables on the right are from the pole, one black load wire and one un-insulated neutral wire. Two or three single-pole switches or breakers, capable of individual operation, shall be permitted on multiwire circuits, one pole for each ungrounded conductor, as one multipole disconnect, provided they are equipped with handle ties or a master handle to disconnect all conductors of the service with no more than six operations of the hand. The Panasonic housing and contact are quite a bit heavier. Exception No. Spare or unused raceways shall also be sealed. 5: Overload protection for 120/240-volt, 3-wire, single-phase dwelling services shall be permitted in accordance with the requirements of 3.10.1.15(b)(6). This brings us to a discussion about panel boxes. Cables that are not approved for mounting in contact with a building or other structure shall be mounted on insulating supports installed at intervals not exceeding 4 500 mm and in a manner that maintains a clearance of not less than 50 mm from the surface over which they pass. The conductors shall not be smaller than 8.0 mm2 (3.2 mm dia.) 2.30.4.10 Protection Against Physical Damage — Underground. See Section 2.25.2.8. This is sometimes referred to as “free trip” or “positive trip” operation. 4: A two-family dwelling or a multifamily dwelling shall be permitted to have one set of service-entrance conductors installed to supply the circuits covered in 2.10.2.7. Exception: An isolating switch shall not be required where the circuit breaker or switch is mounted on removable truck panels or metal- enclosed switchgear units where both of the following conditions apply: (b) Fuses as Isolating Switch. Where the service overcurrent devices are locked or sealed or are not readily accessible to the occupant, branch-circuit overcurrent devices shall be installed on the load side, shall be mounted in a readily accessible location, and shall be of lower ampere rating than the service overcurrent device. It shows how the electrical wires are interconnected and can also show where fixtures and components may be connected to the system. Our switches are Panasonic and Anam. (b) Single-Pole Units. 2.30.1.3 One Building or Other Structure Not to Be Supplied Through Another. He probably did this because he was designing for a foreigner who would have hot water and air conditioning throughout and every conceivable electrical appliance and gadget. Whats people lookup in this blog: Philippine Electrical Code Wire … The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States.It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association.
