Practical Electrical Controls and Safety for Industrial Equipment

By the end of this course, you will be able to:

• Interpret common electrical systems (AC/DC, single‑phase and three‑phase) used in industrial and machine environments
• Assess electrical hazards and apply practical strategies to reduce shock, arc flash, and fire risk
• Evaluate electrical control panels, enclosures, and components for compliance, safety, and workmanship
• Verify machine wiring, grounding, and cable routing against design and regulatory requirements
• Perform structured electrical inspections during fabrication, installation, and field assembly

Description

Electrical systems are foundational to modern machines and industrial equipment, yet many engineers and technical professionals are required to review, install, or inspect them without formal training in how they function or how failures occur. Gaps in understanding can lead to safety risks, compliance issues, unplanned downtime, and costly rework.

This course provides a practical introduction to electrical fundamentals alongside a structured approach to machine‑level electrical inspection. Participants will develop an applied understanding of voltage, current, protection devices, power distribution, and common industrial components, with a strong emphasis on electrical safety and hazard prevention.

Through real‑world examples and inspection‑focused guidance, the course equips professionals to evaluate control panels, machine wiring, labelling, and field installations with confidence. The result is improved decision‑making, safer designs, and higher‑quality electrical installations across industrial projects.

Who This Course Is For

This course is designed for:

• Engineers and engineering technologists working with industrial or automated equipment
• Mechanical, industrial, and systems engineers interacting with electrical designs
• Technical professionals involved in machine design, commissioning, or inspection
• Project engineers responsible for safety, compliance, or quality assurance
• Early‑career to experienced practitioners seeking practical electrical inspection skills

Basic Definitions

• AC current and DC current
• Voltage and Amperage
• Ohm’s Law
• Single-phase, three-phase, or Two-phase?
• Use examples – ex. What we use at home when we say 110V, 208V, what does that mean?
• Usual Voltage of circuits
• Transformers? What are they, and how do they work?
• What happens with a fuse blows? How do we avoid this in design?
• What happens during a power glitch? How do we design to minimize?
• What’s a circuit breaker?
• What is a bus bar?
• What does a typical panel look like? How does it draw power? Make sure it’s cooled; things to keep in mind.
• GFCIs, AFCIs
• What’s the reset and test button on an electrical outlet on the wall?

Electrical Dangers & How to Avoid
