## What is Zavalafy?

Zavalafy is the job-site calculator built for electricians, contractors, and experienced homeowners who need NEC-backed math done right. Stop flipping through codebooks or second-guessing hand calculations. Every tool in Zavalafy runs on NEC formulas with article references built in. You don't just get an answer, you get a defensible one.

CALCULATE IN SECONDS:

Wire Sizing ~ enter your load, material, temp rating, and conduit count. Get the correct AWG with derating applied per NEC 310.15.

Conduit Fill ~ add conductors by gauge, pick your conduit type and trade size. Zavalafy checks the 40% fill rule (NEC Ch. 9, Table 1) and flags violations instantly.

Voltage Drop ~ one-way distance, load, conductor size and material. Instant % drop with a pass/fail against the 3% recommendation.

Load Calc ~ build a complete load schedule, flag continuous loads, and get total VA and demand amps checked against your panel's 80% rule.

ORGANIZE BY JOB:

Every calculation, panel schedule, checklist, and material list lives under a job. Set one active and everything saves to it automatically. No folders, no filing; just work.

BUILD PANEL SCHEDULES:

Add circuits, watch load totals update live, and get brand-specific compatibility warnings. Export a clean PDF panel schedule in one tap.

TRACK INSPECTIONS:

Create checklists for rough, trim, or final inspection. Mark each item Pass, Fail, or flag it with notes and photos. Export a sign-off PDF when you're done.

MATERIALS, AUTO-BUILT:

Choose which calculations to pull into your material list. Add custom line items, adjust quantities, and compare prices across up to three suppliers. One tap searches Home Depot, Lowe's, or Ace Hardware.
