Our house plan called for four lighting circuits, eight outlet circuits and two circuits for our two split air conditioning units. aluminum or copper-clad aluminum. GROUNDING. Our switches are Panasonic and Anam. It should have been 32mm or 1¼”. 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. We feel we were right in the first place in thinking that single pole breakers are a good (and more economical) choice to the 230 volt two wire systems. Most Philippine houses are not wired with three-prong, grounded outlets. Electrical standards and approved codes of practice. To run the main feed into the attic we used 1″ galvanized pipe. The quality of electrical parts on offer is generally poor. Where the voltage exceeds 35,000 volts between conductors that enter a building, they shall terminate in a metal-enclosed switchgear compartment or a vault conforming to the requirements of 4.50.3.1 through 4.50.3.8. The house can look pretty massacred before the thick finishing coat covers all construction sins. The buses on the plug-in panel boxes have a zig-zag type of arrangement which works well if your two buses are hot and you have separate neutral and ground busses – such as in the U.S. or in Manila or other Philippine cities. We did all of the outlet wiring ourselves using outlets made for stranded wire, so we are confident there are no problems with these. This box uses GE-style plug-in breakers. If power consumption exceeds the allowable load supply that it carries, a circuit breaker absorbs the excess amount of energy depending upon its kilo ampere interrupting capacity (KAIC). If there are any electrical engineers out there, they could calculate the difference in resistance losses between the larger and smaller service drops. CLASSIFICATION/NAME OF MATERIALS . You may look up at the utility feed wires leading from the meter or pole to your house — or a neighbor’s house. Cable trays used to support service-entrance conductors shall contain only service-entrance conductors. Exception No. 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. Service-entrance conductors shall be installed by one of the wiring methods covered in 3.0.2.7 and 3.0.2.20. This is a Design Guide according to the provisions of the Philippine Electrical Code. The meter-to-house wire is referred to as “duplex cable”. (9) Fusible disconnect switch or circuit breaker as deemed necessary. Brilliant! However, if you have a 230v two wire supply, you will use one of the buses as a load bus and the other as a neutral bus. 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 capacity of the circuit will be reduced. (d) All Others. Individual meter socket enclosures shall not be considered service equipment. Energized parts shall be enclosed so that they will not be exposed to accidental contact or shall be guarded as in 2.30.5.1(b). In such cases, the service disconnecting means shall be permitted to be electrically operated by a readily accessible, remote-control device. The grounded conductor shall not be less than the minimum size as required by 2.50.2.5(c). (a) Location. Service cables shall be equipped with a raintight service head. The reason that one of the power wires is named “neutral” is because it is connected directly to the building ground connection at the circuit breaker panel. For the purpose of this section, disconnecting means used solely for power monitoring equipment, transient voltage surge suppressors, or the control circuit of the ground-fault protection system or power-operable service disconnecting means, installed as part of the listed equipment, shall not be considered a service disconnecting means. The one or more additional service disconnecting means for fire pumps, emergency systems, legally required standby, or optional standby services permitted by 2.30.1.2 shall be installed remote from the one to six service disconnecting means for normal service to minimize the possibility of simultaneous interruption of supply. Ground-fault protection of equipment shall be provided for solidly grounded wye electrical services of more than 150 volts to ground but not exceeding 600 volts phase-to-phase for each service disconnect rated 1000 amperes or more. Visitors must keep in mind that the Philippines uses the same style of wall outlets as you see in America, but that the outlet is supplying 240 V, not 120 V. Plugging a 120 V appliance into a 240 V outlet will generally destroy the appliance. November 13, 2020 July 9, 2020 by ... Wiring Devices: 1-gang Switch, 10A, 240V: set Service conductors supplying a building or other structure shall not pass through the interior of another building or other structure. (b) Not in Grounded Conductor. 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. Our electricians used them but cut off strands of wire so that they would fit into the switches. However there are some big differences in materials and techniques between the USA, Europe, the U.K. and the Philippines. In a multiple-occupancy building, each occupant shall have access to the occupant’s service disconnecting means. This page was last edited on 22 February 2020, at 11:05. Drip loops shall be formed on individual conductors. It is responsible for the load that supplies power in our homes. We decided to use single-pole breakers. Pursuant to the provisions of Article 165, Chapter II, Book IV of the Labor Code of the Philippines, as amended, and its Implementing Rules and Regulations, Rule 1210 of the Occupational Safety & Health Standards, as amended, it is hereby certified that the electrical wiring works, inspected and tested by … High and low voltage distribution schematic diagrams.! As of June, 2016, the all-time peak … We chose plug-in because that’s what we were familiar with in the U.S. As we will see, that was a mistake. We had to pay for the duplex wire extending from the meter to our house. Service-entrance conductors installed above ground shall be protected against physical damage as specified in 2.30.4.11(a) or (b). cause the service disconnect to open all ungrounded conductors of the faulted circuit. GFI protection in mandatory in much of the world but is expensive and not often seen in the Philippines, despite the fact that electrical shocks and electrocution are a common events here. Since bare feet on tile are a pleasure of Philippine retirement, this is best avoided. Wiring and Protection/Article 2.25 - Outside Branch Circuits And Feeders, PEC:Philippine Electrical Code 2009 Part 1/Chapter 2. Foreigners from places other than the U.S. may have an easier time but, even if their appliances are made for 230v use, have to investigate the compatibility of 50 cycle appliances when used on 60 cycle Philippine circuits. 2: High-impedance shunt circuits, surge arresters, surge-protective capacitors, and instrument transformers (current and voltage) shall be permitted to be connected and installed on the supply side of the service disconnecting means as permitted in 2.30.6.13. would be supplied in the U.S. All small and large appliances sold in the Philippines are designed to use 240 VAC, 60C. We did install battery operated emergency lights to illuminate our front porch and garage during power outages. Perhaps, after being burned (literally!) Anam is a mid-priced Korean brand which seems to be of very good quality. Multiconductor cable shall not be smaller than 8.0 mm 2 (3.2 mm dia.). It’s easy to do before the concrete is poured and very difficult afterwards. The Panasonic outlets are much better and much more expensive. Any information, interpretation and/or annotation presented herein are based on personal opinion of the authors and does not represent the official interpretation of the Philippine Electrical Code. The Philippine electricians we have met have been quite professional. Actuator lever – used to manually trip and reset the circuit breaker. Exception No. (c) Accessible to Licensed electrical practitioner or non licensed electrical practitioner under the supervision of a licensed electrical practitioner Only. Single-pole circuit breakers, grouped in accordance with 2.30.6.2(b), shall be considered as one protective device. Additional installations of ground-fault protective equipment may be needed on feeders and branch circuits where maximum continuity of electrical service is necessary. Sometimes you’ll get a two prong plug with a separate ground wire that the homeowner is left to connect — or not. OUR RECOMMENDATION: We live in an area where electricians are called on to install both 230 volt two-wire systems and 240 volt three-wire systems. Panasonic Wide Series – OK with solid or stranded wire, These Meiji outlets also worked well with stranded wire. Romex-type (NM) cable (several conductors enclosed in a integral plastic sheath) is available, but not generally used.
