Fault current from transformer; working distance → simplified incident energy and PPE category suggestion.
mAh, voltage, and load → hours of use
Total pull tension and bend radius → sidewall bearing pressure
Organize code sections for a project and quickly highlight matches (does not contain code text)
Mixed sizes, THHN/XHHW, ambient & bundling correction, max fill, conduit recommendation.
Labor rate, material cost, overhead, profit margin → price to charge. Quote comparison mode.
Power, usage hours, and rate → kWh and cost per day, month, and year
Whole-home loads, startup surge, fuel type, transfer switch, runtime. Residential & light commercial.
Simple lumen method: room area, target illuminance, and fixture lumens → number of luminaires
Connected loads and demand factor → service load and estimated service current (approximate)
Up to three line items → extended cost and total (quick estimating aid)
V = I × R — enter any two to find the third and power
Build a panel schedule: breakers, phases, neutral load, AFCI/GFCI. Print or copy.
Single- or three-phase: voltage, current, power factor → kW, kVA, and kVAR
Size capacitors to improve power factor and reduce demand.
Residential & small commercial: demand factors, continuous vs non-continuous, EV, generator interlock, 200A/400A recomme…
Find three-phase power, current, and power factor.
Size transformers for load and voltage for power distribution.
Approximate voltage drop and % for a copper run
Multi-segment runs, Cu/Al, temperature, parallel conductors, motor surge, cost comparison, optimize for <3%.
Suggest minimum AWG for a circuit based on length, current, and allowed voltage drop
