Plan RV park electrical distribution—from the service or MDP to each physical RV-site hookup.
Coordinate RV-site demand, physical pedestal routes, park equipment, other calculated loads, service and feeder results, schedules, tagged one-lines, and branded PDF reports in one project.
Built around the real workflow
RV-park projects rarely stop at one demand total. Site equipment, physical pedestal routes, feeder distances, transformer-secondary topology, voltage drop, park equipment, phase loading, schedules, and one-lines have to stay coordinated as the design changes.
RVParkCalc keeps those inputs and outputs in one local Windows project so revisions move through the calculation package instead of being re-entered across separate spreadsheets and drawings.
50-second product walkthrough
Current v1.0.0 application screens show the seven-step workflow, physical RV-site topology, distribution modes, results, and tagged one-lines.
Three project modes
Start with one distribution panel, organize a low-voltage MDP and multiple panels, or carry a 480/277V MDP through park transformers.
Single Distribution Panel Park
Enter the service, panel, direct-fed pedestals or continuing radial runs, dedicated equipment, other loads, distances, wiring methods, and conductor assumptions.
Multi-Panel Park
Configure the low-voltage MDP, add park panels, assign their RV sites and branches, and calculate the upstream distribution from the same project.
Large MDP & Transformer Park
Build a 480/277V MDP, add park transformers, and retain downstream RV-site, equipment, feeder, and panel calculations.
Actual v1.0.0 screens
Every image below comes from the current RVParkCalc v1.0.0 application, not a concept mockup.
One organized path
The app keeps source data, physical routes, downstream branches, calculations, schedules, and diagrams tied to the selected project mode.
Record project metadata, select the RV-site calculation basis, and set the distribution mode.
Add the service, MDP, panels, and transformers that establish the equipment hierarchy.
Enter direct-fed pedestals or ordered continuing radial segments from the serving panel outward.
Enter each dedicated physical branch with its load basis, source, phase, conductors, and OCPD review.
Bring already-calculated VA into the serving equipment and phase that carries the branch.
Start with calculation status and applied notes, then inspect protective features, demand, sizing, grounding, phase loading, feeders, sites, and schedules.
Review the tagged one-line, retain the .rvp project, and export the coordinated PDF report.
See the finished work
The v1.0.0 sample PDF shows one direct-fed RV site on a single panel, a clear calculation status with no automated action items, coordinated schedules, a tagged one-line, and the report assumptions.
Who it is for
Develop and revise RV-park calculation packages without rebuilding separate schedules and one-lines by hand.
Organize the calculation basis, distribution hierarchy, phase loading, feeders, and report information in one project.
Document proposed or existing distribution for review with qualified electrical professionals, utilities, and project stakeholders.
Important: RVParkCalc is a preliminary planning and calculation aid. It does not replace engineering judgment or produce sealed, permit-ready, or construction-ready documents. All inputs, assumptions, equipment selections, code application, and outputs require independent project-specific review.

Questions before purchase
More installation and activation details are available on the support page.
Version 1.0.0 provides single-panel, multi-panel, and large MDP/transformer workflows; physical direct-fed and continuing-radial pedestal topology; Park Equipment and Other Loads; 120/240V and 208Y/120V systems; transformer-primary phase balancing; integral or remote first-secondary-main topology; Chapter 9 raceway voltage-drop modeling; coordinated 3% terminal and 5% complete-path planning; schedules; one-lines; saved projects; and PDF reports.
No. RVParkCalc is a preliminary planning and calculation aid. It does not exercise engineering judgment or create sealed construction documents. Final inputs, assumptions, equipment selections, code application, and outputs must be independently reviewed for the specific project and jurisdiction.
Project calculations and files are local desktop operations. Internet access is required for first activation and periodic license validation, normally every 30 days.
Setup installs RVParkCalc for normal Windows use. Portable runs directly from its folder without a conventional installation. Both contain the same v1.0.0 application and use the same license.
The term begins at the original Gumroad purchase timestamp. Delayed activation, reinstalling, deactivating, or changing devices does not restart or extend it.
The app provides 2023 and 2026 RV-site calculation bases. Confirm the edition adopted for the project, current official text, errata, TIAs, local amendments, utility requirements, and AHJ direction before relying on any result.
