The problem
The tedious part of electrical design shouldn’t take this long.
Drawing the one-line by hand, sizing every breaker and conductor, building schedules cell by cell. Change a single load and it all cascades. It is slow, repetitive, and exactly where mistakes slip in.

FAQ
Frequently asked questions
Does SparkBooksPro replace SKM or ETAP?
No. Those are power-system analysis tools, and you should keep using them. SparkBooksPro automates the production of your one-line, panelboard schedules, and supporting calculations for the construction package.
What files does it produce?
It produces an editable DXF one-line (opens in AutoCAD), Excel panelboard schedules, and a PDF report documenting every calculation.
Can I verify the calculations?
Yes. Every calculation is written out in full in the PDF report, so you can check the math and confirm compliance before you stamp. Calculations follow NEC 2020-2026.
Can I edit the outputs?
Yes. The one-line is a standard DXF you can edit in AutoCAD, and the schedules are standard Excel files.
Do I need to install anything?
No. SparkBooksPro runs in your browser. Your outputs are standard DXF, Excel, and PDF files you download and use in the tools you already have.
From loads to a stamp-ready package.
Your load information is the only input. SparkBooksPro sizes the system, draws the one-line, and documents every calculation. You review and seal.
