Signal snapshot
Different tools light up different parts of the board.
These are the clearest task-fit signals from the official product pages. They are deliberately narrower than an overall ranking.
S-02ANALYSIS
Engineering numbers
CircuitLab + Multisim Live
SPICE, frequency-domain work, plots and component-level analysis are their natural territory.

Source ledger
Every signal has a paper trail.
We checked product pages, documentation, pricing or subscription pages, classroom material and official repositories. “Not confirmed” means the reviewed public source did not say.
01ElectraSimInstallation-first
ElectraSim starts with the objects and conductor roles learners meet on a real domestic board: protection, switching, sockets, loads, line, neutral and earth. Its simulator makes energised paths and common wiring faults visible without requiring live equipment.
02MechSimulator House WiringDirect wiring rival
MechSimulator is the closest like-for-like browser competitor in this review. Its public page describes consumer units, realistic multicore cables, ring and radial circuits, switch layouts, cable sizing, voltage drop and verification checks.
03UK Electrical SIMDomestic training
UK Electrical SIM is aimed directly at domestic training. Its current public site presents a Domestic SIM with final-testing work, plus off-grid and fault-finding areas marked as in progress or under development.
04CircuitLabEngineering analysis
CircuitLab is the analysis-heavy option in this set. Its official material describes in-browser schematic capture, DC, time-domain and frequency-domain simulation, mixed-mode circuits, configurable plots and presentation-quality exports.
05EveryCircuitAnimated electronics
EveryCircuit focuses on immediacy: animated current and voltage, real-time controls, analog and digital components, and an oscilloscope. It is a strong visual electronics companion, not an installation-wiring trainer.
06Falstad / CircuitJS1Open circuit theory
Falstad makes circuit behaviour legible through moving current dots, voltage colours, switches, scopes and editable examples. It is unusually frictionless for theory exploration, while its interface is not organised around domestic installation practice.
07Tinkercad CircuitsClassroom electronics
Tinkercad Circuits is the natural choice when the lesson is about breadboards, Arduino, micro:bit or code. Its broad education ecosystem is a strength, but consumer-unit protection and live-neutral-earth installation logic are outside its stated focus.
08DCACLabManaged virtual lab
DCACLab combines an electronics workbench with meters, a three-channel oscilloscope, public circuits and explicit classroom assignments. That institutional layer is valuable when a teacher needs workflow and progress, but it adds account and subscription overhead.
09Multisim LiveSPICE and lessons
Multisim Live is worth including because it is a familiar SPICE-and-teaching reference, but its own current banner says the online simulator will shut down on 15 September 2026 as the future moves to desktop Multisim.
METHOD / M-01
How to read this bench
- Primary sources first. Claims come from the providers' own public product, documentation, pricing, classroom or repository pages.
- Task-based signals. A five means “strongly aligned with this job,” not “better software.”
- No silent negatives. An undocumented capability is marked “Not confirmed,” never assumed absent.
- Freshness matters. Prices, limits and availability can change; revisit the linked source before making a purchasing or curriculum decision.
Bench notes
Questions that change the choice.
Short answers for the moments when two tools look similar on a feature list.
Q-01Which simulator is the closest match for practical house wiring?
ElectraSim and MechSimulator are the closest browser matches in this review. UK Electrical SIM is also directly aimed at domestic training, but its current workflow is account-based and several modes are marked as in progress. The right choice depends on whether you value an instant, offline-capable PWA or a broader verification-oriented workbench.
Q-02Why are the scores not an overall ranking?
A SPICE simulator, a breadboard classroom and a domestic wiring trainer solve different problems. The six signals on this page describe fit for a specific task, based on what each provider publishes. They do not measure solver accuracy, speed, or product quality against a common benchmark.
Q-03Is ElectraSim a replacement for CircuitLab or Multisim?
No. ElectraSim is the more direct fit for practical installation wiring, protection and fault reasoning. CircuitLab and Multisim are better aligned with engineering schematics, SPICE-style analysis and plots. Multisim Live is also publishing a September 2026 shutdown notice, so check the current desktop transition before starting a new course around it.
Q-04Can any of these tools certify a real installation?
No. A simulator is an educational or design aid, not proof of compliance or safe isolation. Real work still needs competent design, manufacturer instructions, the applicable regulations, inspection, calibrated testing and professional judgement.
