Study Notes
IEC Overview
- IEC was established in 1957 primarily to ensure quality training for apprentice electricians.
- The organization provides a structured program for electrical education and certification.
Credentialing
- Post Graduation test involves a written exam and practical skill demonstration as part of obtaining the IEC National Journeyman Credential.
Yearly Curriculum Breakdown
- 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.
Electrical Concepts
- 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.
Circuit Components
- 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.
Conductors in a System
- 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.
Wiring Infrastructure
- Conduits and cables are essential for delivering electricity from the panel to various endpoints such as receptacles, lights, and appliances.
