Calculate
The math on the page, NEC defaults pre-loaded.
Plan
Lay out the job before you pull a single conductor.
Reference
Code answers with the article cited, every time.
Useful beats subscription-only.
We use them ourselves.
Every tool here is one we wired up because the napkin math kept costing us time. The only difference between our copy and yours is we left the signup gate off.
Trust, not seats.
Tools that should be standard infrastructure shouldn't cost $200/month. We'd rather earn your call when something needs a licensed electrician than charge you to use a calculator.
Built by a licensed master.
Every default value, every NEC reference, every permit field is set by Michael Malfettone (NJ Master #17130). Not a software company in San Francisco guessing at the code.
These tools are calculation aids. Final installation and code compliance are the responsibility of the licensed electrician of record and the local AHJ.
We’re still your neighbors.
Free tools handle the math. Real licensed work — panel upgrades, EV chargers, generators, rewires — that’s a phone call.
