## Description

Version 2.0: NEC 2023 Article Browser, Residential Inspection Checklist, Wire Sizing Suite, and What's New walkthrough — all new in this update.

ElectricalHouse 3D is an interactive 3D visualization and reference app for electricians, electrical inspectors, students, and homeowners. Explore a fully wired residential house in 3D — tap any component to instantly see its NEC code reference, wire gauge, protection type, and real-world function.
VERSION 2.0 ADDS FOUR MAJOR NEW FEATURES
NEC CODE REFERENCE
Browse the complete NEC 2023 by chapter and article. Search across all articles by keyword, tap any article to see key requirements and code section summaries, and bookmark your most-used references for instant access. Covers Articles 90 through 760 — from definitions and grounding to solar PV and fire alarm wiring.
INSPECTION CHECKLIST
A professional-grade pass/fail inspection checklist covering six categories: Service Entrance, Panel and Breakers, Branch Circuits, GFCI/AFCI Protection, Grounding, and Outlets and Devices. Each item is tied to its NEC section. Mark items pass, fail, or N/A, add notes to failed items, track your live score, and generate a summary report showing all failed items with their code references.
WIRE SIZING SUITE
Four calculators in one tool — Ampacity (NEC Table 310.15, with adjustment factors for bundled conductors), Voltage Drop (single- and three-phase, with NEC 210.19 guidance), Conduit Fill (EMT/IMC/RMC with NEC Chapter 9 limits), and Box Fill (conductor, device, and clamp counting per NEC 314.16). Results update in real time as you adjust inputs.
WHAT'S NEW WALKTHROUGH
A guided first-launch screen introduces every new feature so users know exactly what has been added and where to find it.
