Compare Wiring Atlas vs. ZapSketch

Wiring Atlas serves as a comprehensive job management tool tailored for electrical contractors, beginning with a detailed map of each building that includes rooms, levels, panels, circuits, outlets, lights, and EV chargers. Each project is meticulously organized using this map, allowing for the documentation of the scope, inclusions, omissions, as well as tracking change orders along with their financial and schedule implications. Clients receive a detailed approval report that clearly indicates the location of each item, awaiting their signature, while your team is equipped with a job sheet that outlines numbered tasks, their respective rooms, and the corresponding circuits. Upon completion of the work, sign-offs are recorded, ensuring that the job's history remains associated with the building for future reference. Additionally, you can manage customer contacts and follow-ups, invite your team members with appropriate access levels, and easily export your records. The software is designed to operate seamlessly in a web browser and is compatible with tablets for on-site use. The service is available for free to one user managing up to three buildings, while the Pro version is offered at $39 monthly for up to three users, and the Team version can be accessed for $79 monthly, accommodating up to 15 users. This tiered pricing model allows flexibility for contractors depending on their team size and project needs.

ZapSketch is an online tool designed specifically for electricians, electrical contractors, and estimators to facilitate the planning of electrical home runs. It allows users to import floor-plan PDFs, draw walls on a blank canvas, or start from a quick sketch, enabling them to place panels, junction boxes, and devices while routing circuits and raceways efficiently. As users modify their layouts, the application automatically measures run lengths and offers insights on preliminary conductor sizing, ampacity, voltage drop, and conduit fill based on the NEC 2023 standards. Users can also access circuit schedules and export their marked-up plan PDFs along with raceway pull schedules for purposes such as estimating, review, and transitioning to the field; however, some export options and unmarked reports necessitate a Pro subscription. Additionally, there are free standalone calculators available for voltage drop, wire sizing, and conduit fill. While ZapSketch serves as a valuable preliminary planning tool, it is essential to note that it should not replace thorough code reviews, engineering judgment, or the verification of actual project conditions. This tool enhances workflow efficiency and supports better project management for electrical professionals.
