Field Notes

Practical workflows for documenting existing electrical facilities, collecting arc flash study data, and getting the one-line done before you leave the site. Written by a licensed PE. Need to draw one right now? Try the free one-line diagram tool.

• How to document an existing electrical facility that has no drawings

  A practical field workflow for walking a building that lost (or never had) its one-line and coming back with a complete as-built capture in one site visit.

• What data you actually need for an arc flash study: a field checklist

  Every input IEEE 1584 needs, broken down by equipment type. The specific things people miss on the first site visit and end up driving back for.

• Photo-first vs clipboard: a better field data collection workflow for electrical systems

  Why capturing structured data per piece of equipment in the field beats the old clipboard-and-camera approach, and how to run the workflow without a purpose-built tool.
