Philippine Electrical Code Wire Size Table - As utilized in article 3.10, electric ducts shall include any of the electric conduits diagnosed in bankruptcy 3 as appropriate for use underground; different raceways spherical in cross phase, indexed for underground use, and embedded in earth or concrete.
Exception no. 2: conductors in sizes smaller than 50 mm 2 will be authorised to be run in parallel to supply control strength to indicating units, contactors, relays, solenoids, and comparable manipulate devices, supplied all of the following follow:.

This article covers general requirements for conductors and their kind designations, insulations, markings, mechanical strengths, ampacity scores, and uses. Those necessities do not apply to conductors that shape an fundamental a part of system, including motors, motor controllers, and similar gadget, or to conductors mainly furnished for some place else on this code.
(four) adjoining load-carrying conductors — adjoining conductors have the twin impact of raising the ambient temperature and impeding warmth dissipation. Fpn no. 2: conductors hooked up in conduit exposed to direct daylight in close proximity to rooftops have been shown, underneath certain conditions, to enjoy a temperature upward push of 17°c (30°f) above ambient temperature on which the ampacity is primarily based. The following conductors and cables shall be durably marked on the surface. The dimensions in mm 2 or mm diameter will be repeated at durations now not exceeding 600 mm. All different markings will be repeated at intervals not exceeding 1 000 mm. The allowable ampacity tables, the ampacity tables of article 3.10 and the ampacity tables of annex b, the correction elements at the lowest of these tables, and the notes to the tables provide steering for coordinating conductor sizes, sorts, allowable ampacities, ampacities, ambient temperatures, and range of related conductors.
