Simurelay vs Commercial Electrical 3D Guide

Simurelay is a simulator to help you design electromechanical systems and simulate them. It allows to make many electrical diagrams by using the available basic components such as relays, switches, buttons, contactors, timers, motors...

Commercial Electrical 3D Guide puts you inside a fully wired 3-story commercial office building, rendered in real-time 3D with transparent walls so every electrical system is visible at once. Built for electricians, engineers, inspectors, contractors, and students, this is the most detailed interactive electrical reference available on iPhone and iPad. EXPLORE THE 3D BUILDING Rotate, pinch, and zoom through a complete building model showing power distribution from the utility service entrance to branch circuits on every floor. Toggle X-Ray mode to see through walls and trace every conduit run. Filter by system category to isolate exactly what you need. SYSTEMS COVERED Power Distribution: utility transformer, main switchboard, distribution panels, branch circuit panels, automatic transfer switch, bus duct riser, motor control centers, variable frequency drives Emergency Power: generator, ATS, UPS systems, emergency panels, critical load circuits Lighting and Controls: lighting panels, occupancy sensors, daylight controls, emergency lighting, exit signs Low Voltage: data rooms, telecom closets, fire alarm interface, security connections, grounding and bonding Mechanical: chillers, AHUs, cooling towers, pumps, VAV boxes with all electrical connections shown TAP TO LEARN Tap any component to instantly see its full name, NEC code reference, function description, inspection interval, common failure modes, and AHJ notes. Every component is linked to real code data you can use on the job. BUILDING SECTIONS Six 2D section drawings give you a schematic view of the building: three cut sections (A-A, B-B, C-C) and three elevations (West, East, North), all drawn to scale with every component labeled. Tap any symbol to open the tap-to-learn panel. Tap cut line indicators in the 3D scene to jump straight to the matching section view. LEARNING HUB - 8 MODULES Quiz: NEC code questions covering load calculations, conductor sizing, OCPD ratings, and grounding, with full explanations on every answer.
