Rigwise vs BaseCalc Electric Calculator

Rigwise is the rigging calculator built for the field — fast, correct, fully offline, and a one-time purchase. No subscription. No account. No internet required. Your data never leaves your phone. Built for crane riggers, signal persons, ironworkers, and anyone who plans a lift. THE CALCULATORS (always free) • Sling Tension — see how the load in each leg climbs as the sling angle drops. Enter the angle, or just the sling length and height. Clear red warning below 30°. • Working Load Limit — vertical, choker, and basket hitches, with the angle and D/d reduction factors applied. • Center of Gravity — find how much each pick point actually carries when the load is off-center. • Crane Capacity % — check your load against the chart capacity, with a warning when you're over. Every result shows a plain-language safety state, glove-readable, in light or dark. RIGWISE PRO — the studio (one-time purchase, yours forever) • Gear inventory — log your slings, shackles, chains, and hooks with their tagged WLL. • Inspection tracking — Rigwise flags gear that's overdue for inspection before you grab it. • Lift Plans — save a named lift; Rigwise re-computes the numbers from your inputs so a saved plan is never a stale, hand-typed figure. • Field-ready export — share a clean lift-plan summary with your crew. WHY RIGWISE • Works 100% offline — job sites don't have signal. • One-time purchase — the tools you paid for keep working, forever. • Private by design — no account, no tracking, nothing collected. • Correct — the math is deterministic and exhaustively tested against standard rigging practice. SAFETY Rigwise is a calculation aid. Always verify every result against the manufacturer's tag, the load chart, and a qualified person. It is not a substitute for an engineered lift plan or professional judgment. Rigging is inherently hazardous; you are solely responsible for the safety of any lift.

BaseCalc Electric Calculator is an NEC-aware electrician calculator for job-site field math, worksheets, materials, and saved calculation history. Run voltage drop, wire size, conduit fill, service load, breaker, grounding, EV charger, generator, and other electrical calculator checks on site, then save the result for the job. 18 CALCULATORS FOR DAILY FIELD WORK • Ohm's Law — solve voltage, current, resistance, and power from any two known values. • Voltage Drop — single-phase or three-phase, copper or aluminum, with a 3% target check. • Wire Size — minimum conductor sizing based on NEC 310.16 ampacity with temperature and conductor-count adjustment. • Conduit Fill — fill percentage for EMT, PVC, RMC, IMC, FMC, and LFNC. • Conduit Size — auto-recommend the first raceway size that passes fill. • Box Fill — required box volume per NEC 314.16. • Conduit Bend — fast offset bend mark calculations. • Bend Layout — rolling offsets, 3-point saddles, and 4-point saddle layout guidance. • Service Load — dwelling service/load sizing guide based on NEC 220 concepts. • Breaker + Wire — continuous-load OCPD and conductor guidance. • Grounding — EGC and GEC starting-point sizing. • Motor Circuit — FLC, conductor ampacity, overload, and short-circuit/ground-fault guides. • Pull Box — straight, angle, and U-pull box dimension guide. • Derating — temperature correction and current-carrying conductor adjustment. • EV Charger — branch circuit and service-load check. • Generator — backup generator kW and output-current target. • Transformer — kVA to full-load amperage. • Power — kW, kVA, current, voltage, and power factor relationships. EVERY RESULT IS EXPLAINED • Clear pass/fail or sizing messages. • The governing limit, final answer, and calculation breakdown. • Saved local history so you keep a job-site record. DEVICE-LOCAL FOR THE FIELD • Works offline by default. • No BaseCalc account or cloud sync. • Job contact, worksheet, setting, and calculation data is stored in local app storage, protected by your device security. • There is no BaseCalc cloud option. • Device backups, when available on your operating system, remain under your device-account settings. • Dark and light themes with a high-contrast job-site interface. BaseCalc Electric is a professional reference tool. Always verify against the current National Electrical Code and your local amendments. The authority having jurisdiction has the final say.
