Commercial Electrical Inspection Video Overview
Get a step-by-step look at how to inspect electrical equipment in commercial buildings, including multi-building properties. This video traces power from the utility-side to the service entrance equipment and downstream components. It also demonstrates how to apply the International Standards of Practice for Inspecting Commercial Properties (ComSOP) to guide your process and stay organized.
What’s Covered
- Applying consistent electrical inspection and safety procedures
- Inspecting service entrance equipment, meter enclosures, and disconnects
- Reading electrical equipment labels
- Determining system voltage and amperage ratings
- Evaluating clearance and access around electrical equipment
- Assessing overcurrent protection at main panels and subpanels
- Recognizing when building-side transformers are in use
- Understanding multi-building layouts, power distribution, and CT panel splits
Why Consistent Inspection Procedures Matter
During the electrical portion of a commercial property inspection, it’s important to follow a consistent process. When you develop a process that works for you, it can apply to a single building or a property with multiple buildings.
Starting at the utility-side and working downstream helps you document key components and understand how power is distributed throughout the system. Utilize your preliminary walk-through to begin understanding how power is distributed and managed across the property or an individual building.
The electrical for commercial buildings can vary widely in layout and power setup, but your scope remains performing a visual inspection and documenting an inventory of the system’s equipment.
