How to Bend Conduit

Use a hand bender to mark, align, and bend EMT conduit precisely. Apply steady pressure for clean 90°, offset, or saddle bends. This ensures proper routing and code compliance in electrical installations. How to bend conduit Use a hand bender to mark, align, and bend EMT conduit precisely. Apply steady pressure for clean 90°, offset, or saddle bends. This ensures proper routing and code compliance in electrical installations. Using the right tools and techniques, you can achieve precise bends—including 90-degree angles, offsets, and saddles—to navigate obstacles and fit conduit into tight spaces. This guide walks you through the process…

Data Logger Explained

Data logger for electrical engineering applications, enabling data acquisition from sensors, high-resolution measurement, time-series recording, telemetry, calibration, and IoT monitoring for power quality, energy metering, equipment diagnostics, and load profiling. Data Logger Overview and Best Practices A data logger (or sometimes called a "datalogger") is a specialized electronic device that measures and records specific data over a certain period of time or in relation to its location either with a built-in instrument or sensor or via external instruments and sensors.Datalogging is a term used to describe using a device to collect data through a sensor. That way, the data can be analyzed and saved…

Surge Protection for Electrical Panel: Why Placement Matters

Surge protection for an electrical panel controls how transient voltages enter and spread through branch circuits inside the panel, limiting internal equipment damage when external or switching surges reach the distribution point, rather than assuming upstream protection is sufficient. It is not about whether a surge device is installed, but whether it is positioned where surge energy actually enters and is redistributed within a system. Panels act as electrical crossroads. When surge protection is misunderstood as a general safeguard rather than a boundary control, sensitive branch circuits remain exposed even in buildings that appear “protected.” This is why surge damage…

Automatic Transfer Switch

An automatic transfer switch (ATS) seamlessly shifts electrical load from the utility to a backup generator during power outages. It ensures continuous power, improves safety, and protects sensitive equipment from unexpected power loss or fluctuations. How an Automatic Transfer Switch Works Emergency Generator Standby Power Training Power Quality Analysis Training Request a Free Emergency Generator Training Quotation Technical Depth: Controllers and Monitoring Logic Modern automatic transfer switches rely on intelligent control systems to ensure seamless and safe operation during power outages. These controllers are the "brains" of the automatic transfer switch, constantly monitoring utility and generator power for…

Arc Flash PPE Category: What Each Level Requires and How to Select the Right One

Arc flash PPE category is an incident energy threshold defined by NFPA 70E and CSA Z462. Each of the four categories sets a minimum arc rating in cal/cm2 required to prevent second-degree burns at a specific exposure level. The category a task falls into determines whether a worker's protective system can survive what the system is capable of releasing, and assigning the wrong one produces consequences that are physical before they are regulatory. Arc Flash PPE Category: Why the Classification? A Category 2 suit worn on a Category 4 task does not provide partial protection. It fails at the…

Electrical Power Transformers Explained

Electrical power transformers are electrical devices commonly used in engineering that transforms both the voltage and the current of the electricity flowing through it. It is made up of a coil wrapped around an electromagnet that transfers the electricity. Unlike distribution transformers, power transformers are designed to operate at 100% efficiency (distribution transformers operate at a maximum efficiency of only 60-70%). Another main difference between distribution and electrical power transformers is that power transformers are meant to handle high voltages, whereas distribution transformers are meant to handle lower voltages. Power transformers transfer power to distribution transformers, so that the distribution transformers…
