Trimble Electrical Designer is a suite for electrical engineers and contractors designing, calculating and validating low-voltage electrical systems. Its tools cover 2D electrical system design, circuit visualization, cable and busbar sizing, voltage-drop checks, fault analysis, selectivity checks, arc-flash calculations and reporting. The suite supports BS 7671, IEC 60364, ADDC & DEWA, NEN 1010 and VDE 100, making it suited to teams working across several regional standards.

Pricing follows a contact-sales model, with three 2D bundles. Base includes ProDesign MR 25, Protect LV MR and SingleCable Pro MR, along with instant access updates and Trimble MEP support. Pro raises the included ProDesign level to MR 100 and adds Protect HV MR while retaining SingleCable Pro MR, updates and support. Pro+ includes ProDesign MR 400, Protect HV MR, SingleCable Pro MR and PowerNet MR, plus the same updates and support. The bundle structure maps the offering to smaller designs, more advanced protection work and complex high-voltage or short-circuit-analysis projects, while buyers engage Trimble for pricing.

The strongest fit is standards-based calculation work where engineers need voltage-drop, line- and earth-fault adiabatic, load, selectivity and arc-flash checks in one suite. Arc-flash calculations follow IEEE 1584-2018 and NFPA 70E, and manufacturer-approved data covers protective devices, cables and busbars. Trimble Assistant adds an AI tool to the workflow. Choose Trimble Electrical Designer when calculation depth, regional standards and formal reports matter most. Teams seeking a wider integration ecosystem or a broader platform beyond focused 2D electrical design should consider alternatives.
