IEC Manual Review Flashcards

IEC was established in 1957 primarily to ensure quality training for apprentice electricians.
The organization provides a structured program for electrical education and certification.

Post Graduation test involves a written exam and practical skill demonstration as part of obtaining the IEC National Journeyman Credential.

1st Year: Focuses on navigating the code book, understanding its organization, and locating information efficiently.
2nd Year: Delves deeper into the code book to interpret codes effectively.
3rd & 4th Years: Covers advanced topics like motor controls and basic circuit design, emphasizing series and parallel wiring.

Voltage represents the electromotive force or potential difference, measured in volts; likened to pressure in how electricity flows through conductors.
Ampacity is the maximum electric current (in amps) that can traverse a wire; larger conductor sizes correspond to higher ampacity.
Wattage quantifies the power (in watts) required by a device, calculated as a product of amps and volts; represented as "P", "W", or "VA".
Resistance denotes the opposition to electric current flow, measured in ohms; higher resistance correlates with lower current.

Circuits typically originate from a panel, serving as the main control point for electricity distribution.
Circuit breakers automatically interrupt a circuit when current exceeds preset limits, protecting wires from overcurrent conditions.

Ungrounded conductor (Hot) is part of a circuit that provides power but is not grounded, essential for supplying electricity to devices.
Grounded conductor (Neutral) returns current to the panel, completing the circuit and is connected to ground for safety.
Grounding conductor links equipment to ground electrodes, ensuring safe disconnection of circuits during faults to avert hazardous situations.
