Protective Device Selection and Coordination Training Course 1

Overview of the Protective Device Selection and Coordination Training Course

ICTESS’s Protective Device Selection and Coordination Training Course is designed to train specialists in analyzing, selecting, and configuring protective devices for low- and medium-voltage electrical systems. The program covers everything from the fundamentals of time-current curves to advanced techniques for selective coordination between upstream and downstream protective devices.

You’ll learn the selectivity criteria that engineers apply on real-world projects: reading trip curves, selecting circuit breakers and residual-current devices in line with the National Electrical Code (NEC), calculating short-circuit currents, verifying interrupting ratings, and testing methodologies used to validate coordination. The course includes a capstone project in which you’ll apply everything you’ve learned to design a complete protection scheme.

Purpose of the Protective Device Selection and Coordination Training Course

The Protective Device Selection and Coordination Training Course addresses a critical need in the electrical industry: keeping people and equipment safe through protection systems that are properly sized and coordinated. Poor selectivity can trigger nuisance tripping that disrupts service continuity, or worse, protection failures during short circuits that put both the installation and the people working on it at risk.

The course’s purpose is to train professionals who can design protection schemes that achieve full selective coordination between devices. You’ll learn to read manufacturer time-current curves, select the optimal combination of circuit breakers, fuses, and residual-current devices, calculate short-circuit currents at any point in an installation, and confirm that each device operates before the one immediately upstream.

The training also covers professional calculation software used across the industry, and culminates in a capstone project where you’ll develop a full selectivity study for a real installation with multiple levels of protection.

What the Protective Device Selection and Coordination Training Course Prepares You For

The Protective Device Selection and Coordination Training Course prepares you for specialized technical roles at electrical engineering firms, licensed electrical contractors, industrial maintenance departments, and project consultancies. You can work as an electrical design engineer, a protection specialist in industrial facilities, a commissioning technician, or a selectivity and short-circuit study specialist.

The training prepares you to manage protection projects from design through final verification: performing short-circuit studies on distribution systems, sizing protective devices in accordance with the National Electrical Code (NEC), developing one-line diagrams with selective coordination, configuring protective relays, and running test protocols to confirm each device performs correctly.

You’ll also learn to audit existing installations, identify coordination deficiencies, recommend improvements, and prepare selectivity reports that meet AHJ documentation requirements. The hands-on approach lets you apply what you learn directly to real industry projects.

RENEWABLE ENERGY FACULTY

Train for a career the industry actually needs

Importance of the Protective Device Selection and Coordination Training Course

The electrical industry is dealing with increasingly complex installations as renewable energy, storage systems, and non-linear loads become more common. This shift demands professionals who can design protection schemes suited to new network topologies. Coordination failures cause service interruptions with significant economic costs and, in serious cases, put the safety of people and equipment at risk.

A Shortage of Selectivity Specialists: The job market faces a shortage of technicians with deep expertise in protection coordination. Many professionals know the basics of device selection but lack the skills to carry out full selectivity studies, verify compatibility between protection levels, or correctly interpret manufacturer curves.

Increasingly Demanding Codes and Standards: Updates to the National Electrical Code (NEC) and related standards are setting stricter requirements for overcurrent and fault protection. The Authority Having Jurisdiction increasingly requires documented selectivity studies, driving demand for professionals who can prepare this technical documentation.

A Competitive Edge in the Job Market: Specializing in protection coordination sets you apart significantly from generalist profiles. Mastering short-circuit calculations, selectivity techniques, and professional software positions you as a top candidate at engineering firms, contractors, and industrial maintenance departments.

Benefits of the Protective Device Selection and Coordination Training Course

Completing the Protective Device Selection and Coordination Course positions you as a specialist in a critical area with strong demand. Industrial, commercial, and infrastructure installations need technicians who guarantee safety and service continuity through properly coordinated protection systems.

Access to Specialized Technical Roles: You can pursue roles like protection design engineer, commissioning technician, panel maintenance lead, or selectivity consultant. Specializing in protection coordination opens doors to more complex, higher-responsibility projects.

Mastery of Professional Tools: Hands-on experience with industry-standard software sets you apart, as these are essential in engineering firms. Practical command of these platforms shows your ability to develop selectivity studies with professional rigor.

Ability to Ensure Installation Safety: You’ll learn to design protection systems that meet code requirements and protect people and equipment, taking on high-level responsibility for verifying electrical schemes.

Recognized Professional Certificate: The ICTESS professional certificate validates your technical specialization in protective device selection and coordination, strengthening your position in the electrical and industrial job market.

Capstone Project for the Protective Device Selection and Coordination Training Course

The capstone project is the culminating stage of the program and represents the practical integration of every technical skill developed throughout the course. It involves developing a complete selectivity study for a real electrical installation, from network analysis through to final documentation for submission to the Authority Having Jurisdiction (AHJ), applying the professional methods and calculation tools used across the industry.

The project is based on an installation with multiple levels of protection, including a main low-voltage switchboard, secondary panels, and branch circuits. You’ll calculate short-circuit currents at every significant point in the installation, select protective devices in accordance with the National Electrical Code (NEC), verify the interrupting rating of each device, design upstream and downstream coordination using selectivity techniques, and plot overlapping time-current curves to demonstrate correct coordination.

The project also includes verifying ground-fault protection with a vertical selectivity analysis, documenting the complete one-line diagram with technical specifications for each device, and preparing a selectivity report in the professional format required by the authority having jurisdiction. The final documentation must demonstrate your ability to produce rigorous technical studies that ensure safety and service continuity in professional electrical installations.
