Electrical Calc Elite vs Panel Planner

Electrical Calc Elite™ is the electrician's code calculator that follows the NEC® edition your inspector enforces. Size wire, check voltage drop, fill conduit and size motor circuits — offline, in seconds. Answers that come from a code table print which one. One purchase, no subscription. Ten editions of the National Electrical Code® are built in — NEC® 2026*, 2023, 2020, 2017, 2014, 2011, 2008, 2005, 2002 and 1999 — and every table, correction factor and code reference follows the one you select. BUILT FOR Electricians, contractors, estimators, engineers, maintenance techs, inspectors, apprentices studying for the exam, and homeowners checking their work. WIRE SIZE AND AMPACITY • Required wire size in AWG or kcmil from amps: copper or aluminum, single-phase or three-phase, 60/75/90°C insulation, at 100% or 125% • Ampacity in raceway or free air, from the NEC® ampacity tables (310.16 and 310.17, or the earlier equivalents) • Ambient temperature correction above or below 30°C, in °C or °F • Adjustment for more than three current-carrying conductors in a raceway • Parallel and derated conductor sizing • Circular mils and kcmil for any wire size VOLTAGE DROP • Volts and percent dropped from one-way length, amps, phase and wire size, with Chapter 9 Table 8 resistance corrected to 60, 75 or 90°C • Wire size for a long run, flagged VD WIRE SIZE when the drop, not the ampacity table, set it • Longest one-way run a wire size will carry inside your limit: 3% by default, or any limit you set • 1- or 3-phase, copper or aluminum, feet or meters; wire resistance per 1000 ft on its own key CONDUIT SIZING AND FILL • 12 conduit types: EMT, ENT, FMC, IMC, LFNA, LFNB, LFMC, RMC, PVC schedule 40 and 80, Type A and Type EB • Trade size for a mix of THW/THHW, XHH/XHHW or THHN/THWN conductors • Fill percentage, cross-sectional area and area remaining, from the Chapter 9 tables, with the correct 1-, 2- and over-2-wire fill limits • Maximum conductors of a given size a conduit will take MOTORS • Full-load current for 1-phase, 3-phase, synchronous and DC motors, from NEC® Tables 430.247, 430.248 and 430.250 • Horsepower from amps, and full-load amps from horsepower • Maximum fuse and breaker size from Table 430.52 (430.52(C)(1) in 2023 and 2026) — single-element or dual-element fuse, inverse-time or instantaneous-trip breaker, across seven motor types • Motor overload protection per 430.32(A)(1) • NEMA starter size, per NEMA ICS 2 GROUNDING • Equipment grounding conductor size, per 250.122 • Grounding electrode conductor size, per 250.66 POWER, MATH AND CONVERSIONS • Convert between amps, watts, volts, VA, kVA, kW, power factor %, efficiency % and DC resistance • Ohm's Law: enter any two of ohms, volts or amps to get the third • Kirchhoff's Law • Parallel resistance • BTU ↔ kilowatt-hours • Doubles as a standard calculator, with Store and Recall memory keys CODE REFERENCES YOU CAN CHECK Wire size, fuse, breaker, overload and grounding answers print the table or section they came from, numbered as your selected edition numbers it. Fuse and breaker cards show the percentage of full-load current used and the current it was applied to. HELP BUILT IN Hold any function key to open the manual at that key's own section. A Help key opens it from the front, with worked keystroke examples. A Getting Started guide and the full manual are included. WORKS OFFLINE Every calculation runs on the device. No account, no sign-in, no ads, and no waiting on a signal in a basement or a mechanical room.

Plan, visualize, and manage your home's electrical system — right from your iPhone. Circuit Breaker Panel is an interactive residential electrical panel simulator that lets you map out every circuit in your home, track real-time current loads, and plan new circuits before you ever call an electrician. BUILD YOUR PANEL Install single-pole (120V) and double-pole (240V) breakers in any configuration. Choose from 15A, 20A, 30A, 40A, 50A, and 60A ratings. Support for 24, 30, and 40-slot panels with 100A, 150A, 200A, and 400A main breakers. ADD YOUR DEVICES Populate each circuit with the real appliances and devices in your home. Choose from 20 common presets — refrigerator, HVAC, EV charger, dryer, and more — or enter any custom wattage. Toggle devices on and off to simulate real-world usage scenarios. LIVE LOAD CALCULATIONS Current draw is calculated automatically for every circuit (Amps = Watts ÷ Voltage). Watch each breaker's load bar update in real time as you switch devices on and off. COLOR-CODED SAFETY STATUS Know at a glance which circuits are safe and which are at risk: Green glow — circuit is within safe range (under 70% load) Yellow glow — load is climbing, approaching capacity (70–90%) Red pulsing glow — circuit is overloaded, breaker would trip (over 90%) SAVE UP TO 10 PANELS Save and restore up to 10 complete panel configurations. Perfect for planning a renovation, comparing layouts, or managing panels across multiple properties. DESIGNED FOR CLARITY A realistic panel enclosure with a center bus bar, physical breaker switches, and load bars on every circuit give you an intuitive feel for your home's electrical system — no electrical engineering degree required. FULLY OFFLINE & PRIVATE No account. No internet connection. No data collection of any kind. Your panel configurations are stored only on your device.
