Commercial Electrical Designer app analytics for October 13

This app is a visual reference and calculation tool for electrical engineers, designers, electricians, and students working on commercial building projects. Built around a real-world commercial strip mall, this app puts professional electrical illustrations, NEC code look-up, interactive calculators, step-by-step design calculation guides, a project checklist, and an electrical glossary in one place — offline, on iPhone and iPad. BROWSE — ILLUSTRATED DRAWINGS 23 professional illustrations in 8 design categories: Floor Plans & Key Plans — dimensioned tenant layouts and color-coded key plans Electrical Plans — device plans with lighting, receptacles, switches, and panels Wiring Layouts — branch circuit home runs and wiring path diagrams Electrical Symbols & Legend — full device symbol reference Panelboard Schedules — 200A, 208Y/120V, 3-phase schedules for Shops A, B, C, and the Building 2 main distribution panel Panelboard Load Worksheets — conductor sizing tables with OCPD ratings and wire sizes per circuit Feeder Load Calculation Worksheets — NEC Article 220 calculations for each tenant and the building main Conductor & Conduit Sizing Steps — step-by-step sizing sheets for phase, neutral, and grounding conductors Pinch to zoom up to 6× on any illustration. Swipe between images in the same category. Save any illustration to Favorites for fast retrieval. NEC REFERENCE Searchable, expandable code cards for the articles most relevant to commercial design: Article 210 (Branch Circuits), 215 (Feeders), 220 (Calculations), 230 (Services), 240 (Overcurrent Protection), 250 (Grounding and Bonding), 310 (Conductors), and 408 (Panelboards). CALCULATORS Ten interactive calculators covering the full commercial design workflow: Branch Circuit Load, Feeder Load, Voltage Drop, Wire Sizing, Conduit Fill, Panel Load Balance, Demand Factor, Short Circuit Current, Power Factor Correction, and Service Size. DESIGN CALCULATIONS Seven step-by-step calculation modules with NEC references, formulas, and worked examples: Branch Circuit Load Worksheet, Feeder Load Calculation, Phase Conductor Sizing, Neutral Conductor Sizing, Equipment Grounding Conductor, Conduit Fill & Trade Size, and Panelboard Load & Phase Balancing — including a full Building 2 Panel L1 worked example. PROJECT CHECKLIST (NEW IN 1.1) A phase-by-phase checklist covering the full commercial electrical project workflow — Pre-Design, Load Calculations, Conductor Sizing, Panelboard Design, Drawing Set, Permit & Approval, and Final Inspection. Each item includes the applicable NEC reference. Progress is tracked automatically and saved between sessions. ELECTRICAL GLOSSARY (NEW IN 1.1) 55+ NEC and electrical engineering terms with plain-language definitions and code references — alphabetically indexed and fully searchable. Covers key terms including Ampacity, Branch Circuit, Continuous Load, Demand Factor, EGC, Feeder, FLA, GFCI, AFCI, OCPD, Power Factor, Service Entrance, Unit Load, Voltage Drop, and more. FOR iPHONE AND iPAD Fully responsive layout adapts to any screen size and orientation. All content is available offline — no subscription or account required. Ideal for electrical engineering students, practicing engineers, electrical designers, contractors, and inspection professionals working with NEC-based commercial electrical systems.
