Philippine Electrical Code – Objectionable Current

What is Objectionable Current?

The term "objectionable current" in the context of the Philippine Electrical Code (PEC) refers to the presence of current flow on grounding conductors or grounding paths that are not intended to carry current during normal operation. The PEC addresses objectionable current in Article 2.50.1.6, which highlights the need to minimize or eliminate such currents because...

Philippine Electrical Code – General Requirements for Grounding and Bonding

Performance-based requirements establish overall objectives without prescribing specific methods to achieve them. The opening paragraph of Section 2.50.1.4 explains that the performance objectives outlined in 2.50.1.4(A) for grounded systems and 2.50.1.4(B) for ungrounded systems can be met by adhering to the detailed prescriptive requirements set forth in Article 2.50 - Grounding and Bonding. Section 2.50.1.4 does not dictate specific rules...

Philippine Electrical Code – Separately Derived System

The PEC has defined a Separately Derived System as an electrical source, other than a service, having no direct connection(s) to circuit conductors of any other electrical source other than those established by grounding and bonding connections.

Examples

Examples of separately derived systems include generators, batteries, converter windings, transformers, and solar photovoltaic systems, provided they have no direct electrical connection...
