Philippine Electrical Code Quiz

What is the primary purpose of the Philippine Electrical Code (PEC)?

• To promote energy efficiency

• To ensure safety for individuals and property through guidelines for electrical systems

• To regulate the cost of electricity

• To provide aesthetic standards for electrical installations

Answer explanation

Safety Regulations: The PEC aims to ensure safety for individuals and property by providing guidelines for electrical design, wiring, equipment selection, grounding, and protection against electrical hazards.

Which settings does the PEC apply to?

• Only residential installations

• Only commercial installations

• Residential, commercial, and industrial installations

• Only public buildings

Answer explanation

Wide Applicability: It applies to various settings, including residential, commercial, and industrial installations, covering everything from public buildings to temporary substations.

What is one of the key features of the PEC?

• Guidelines for aesthetic design

• Standards for grounding and bonding electrical systems

• Regulations on energy consumption

• Specifications for building materials

Answer explanation

Key Features

1. General Requirements: This section outlines the scope, definitions, and principles for electrical installations.

   • Wiring Methods: Guidelines for selecting and installing wiring systems, including cable types and conductors.

   • Grounding and Bonding: Standards for grounding electrical systems to prevent electrical shock and ensure system reliability.

   • Overcurrent Protection: Specifies requirements for protective devices like circuit breakers to prevent overloads

What is required before any electrical installation can commence according to the PEC?

• Environmental clearance

• Electrical permit and inspections

• Zoning approval

• Fire safety inspection

Answer explanation

Mandatory Compliance: Adherence to the PEC is legally required for all electrical installations in the Philippines. This includes obtaining necessary permits and conducting inspections during installation.

Who must oversee all electrical works to ensure compliance with the PEC?

• Unlicensed electricians

• Licensed electrical engineers or registered practitioners

• Local government officials

• Property owners

Answer explanation

Professional Oversight: Licensed electrical engineers or registered practitioners must oversee all electrical works to ensure compliance with the code.

What is a significant consequence of non-compliance with the PEC?

• Increased energy bills

• Legal consequences and potential impact on insurance coverage

• Mandatory training for workers

• Reduced property value

Answer explanation

Legal and Insurance Implications: Non-compliance can result in legal consequences and may affect insurance coverage in case of accidents related to electrical installations.

The PEC is primarily based on which international standard?

• International Organization for Standardization (ISO)

• National Electrical Code (NEC) of the United States

• European Union Electrical Standards

Answer explanation

The PEC is primarily based on the National Electrical Code (NEC) of the United States. However, it includes modifications tailored to local conditions in the Philippines.

What does the PEC specify regarding overcurrent protection?

• It is optional based on installation type.

• Requirements for protective devices like circuit breakers to prevent overloads.

• Only fuses are allowed as protective devices.

• No protection is needed in residential areas.

Why is compliance with the PEC important for accident prevention?

• It ensures that all materials used are aesthetically pleasing.

• It helps reduce the risk of electrical accidents, such as fires and electrocutions.

• It allows for faster construction timelines.

• It mandates the use of renewable energy sources.

Answer explanation

Accident Prevention: Following the PEC helps reduce the risk of electrical accidents, such as fires and electrocutions, by enforcing strict safety standards.

How often is the PEC updated?

• Every year

• Regularly, to incorporate technological advancements

• Once every decade

• It has not been updated since its inception.

Answer explanation

The PEC is regularly updated to incorporate technological advancements.
