Electrical Drafting Blog

Plain, practical guides for contractors, installers and project managers who need plan sets that pass review the first time: what goes on each sheet, why AHJs send sets back, and how clean as-builts close out a job.

Guides from the drafting bench

These guides come straight from daily drafting work: building solar permit sets sheet by sheet, answering AHJ correction comments, and turning field redlines into clean record files. Each guide sticks to what a contractor can check, send or fix in real project work. No theory for its own sake, and no sales talk dressed up as advice.

Start with the solar permit set walk-through if you submit PV work. Read the AHJ rejection guide if correction cycles keep eating your schedule. And keep the as-built guide for closeout season, when owners and general contractors ask for final files and the field markups are still in a job folder somewhere.
