RVParkCalc Version History

Current release

Version 1.0.0

July 2026

Single Distribution Panel Park for one panel and its RV-site distribution.
Multi-Panel Park for a low-voltage MDP and multiple distribution panels.
Large MDP & Transformer Park for a 480Y/277V MDP, park-owned transformers, and downstream panels.

Direct-fed single- or dual-sided physical pedestals with one panel-to-pedestal supply.
Ordered one-source continuing-radial runs with one or two separately counted sites at each pedestal, downstream demand by segment, cumulative voltage drop, and a uniform run conductor arrangement.
One row per physical Park Equipment or Other Load branch, with migration of former schema-4 quantities into separate schema-5 rows.
First-class 120/240V single-phase and 208Y/120V three-phase workflows, including 50A two-pole RV-site phase assignments on three-phase systems.

Seven steps: Project, Distribution, RV Site Distribution, Park Equipment, Other Loads, Results, and One-Line.
Service, feeder, panel, transformer, transformer-secondary, pedestal, site-assignment, Park Equipment, and Other Load results and schedules as applicable to the selected mode.
Automatic primary-phase balancing for applicable single-phase transformers and explicit integral or remote first-secondary-main topology.
Remote transformer-secondary segments through 25 ft with 10 ft / 25 ft rule identification, supply-side bonding-jumper planning, and source-OCPD continuity.
Supported-method conductor, full-size neutral, EGC, raceway-fill, and phase-loading planning, including Chapter 9 Table 9 raceway impedance and joint 3% terminal / 5% complete-path voltage-drop coordination.
Required protective-feature scheduling by One-Line tag, including modeled GFPE and arc-energy-reduction thresholds.
Service grounding-electrode-conductor and main-bonding-jumper planning, plus transformer grounding and bonding results for applicable large-park configurations.
Tagged source-to-load one-lines, schema-versioned .rvp project files, local draft recovery, and coordinated branded PDF reports.

Setup and Portable builds for Windows 10 or Windows 11, 64-bit.
One 365-day term beginning at the original Gumroad purchase timestamp, with no automatic renewal.
Online activation and periodic validation, normally every 30 days, with up to three device activations unless the purchased quantity grants more.
Encrypted local activation record; project-file and report contents are not sent as part of Gumroad validation.
