build it.

PickettPanel lets you design and simulate hardwired control circuits — start/stop stations, relay logic, DOL motor starters and VFD drives — directly in your browser. Inject faults and find them with a real, phase-aware multimeter. No software to install.

Built-in circuits

Load a circuit.

Seven built-in presets, fully interactive — press the buttons, watch the current flow, trip the protection. Build from these or start from scratch.

Start/Stop with Seal-In circuit running in PickettPanel — energised cyan wires, green RUN lamp, CR1 picked
Start / Stop with Seal-In

The foundation of hardwired motor control. A CR contact holds the circuit closed after you release the start button.

FUNDAMENTAL
DOL Motor Starter running in PickettPanel — contactor poles energised, 3-phase motor running, overload relay visible
DOL Motor Starter

MCCB, contactor poles and thermal overload feeding a 3-phase motor. Single-phase the motor and watch the overload heat up and trip.

MOTOR CONTROL
VFD Drive circuit in PickettPanel — drive showing RUNNING, motor active, control wiring and fault lamp visible
VFD Drive Circuit

Three-phase supply, drive and motor with 3-wire control. Overload the motor and the drive OC-trips — reset it on DI3, like the real thing.

Who uses PickettPanel

Built for the bench.
Tested in the classroom.

Two audiences. One tool. Different reasons it saves them time.

🎓
Trades Students & Apprentices
City & Guilds · SOLAS · ETCB

Hardwired control circuits appear in every electrical apprenticeship assessment. Most students only get to practise them during lab sessions — limited time, shared equipment, instructor waiting.

PickettPanel gives you unlimited practice time. Build the circuit at home, understand why the seal-in contact works before you wire a real panel.

  • Simulate before the lab session
  • Understand relay logic visually
  • Prep for City & Guilds, SOLAS assessments
  • No electrical hazard while learning

Panel Builders & Technicians
Industrial · Manufacturing · Automation

A wiring error on a commissioned panel costs time, credibility, and sometimes components. Proving the control circuit logic before you wire is faster than tracing faults after.

PickettPanel Lite already exports IEC-style PDF schematics with wire numbers and title blocks. A Pro version with commercial documentation features is in the works.

  • Verify control circuit logic before wiring
  • Wire numbering for documentation
  • IEC-style component symbols
  • Export to PDF for job records

FAQ

Quick answers.

Is PickettPanel free?

Yes — PickettPanel Lite is free and runs entirely in your browser, no sign-up. It includes the full simulator: motor control, VFD drives, fault injection, the multimeter, PLC ladder logic and PDF export. A Pro version with commercial documentation features is planned.

What circuits can I simulate?

Start/stop stations with seal-in, indicator logic, on-delay timers, DOL motor starters with a thermal overload, and VFD drive circuits with a 3-phase motor. Protection trips realistically — fuses on I²t, overloads thermally, MCCBs with thermal + instantaneous elements, and the drive's own electronic overload.

Can I practise electrical fault finding?

Yes. Inject broken wires, welded contacts, open coils, motor winding faults, single phasing or drive faults — or let the random-fault trainer hide one. Then find it with the multimeter: the leads stay attached while you operate the circuit, and it reads continuity, phase-to-neutral (~230V) and line-to-line (~400V) like a real installation.

Does it use proper IEC symbols?

Yes — IEC 60617 conventions throughout, including correct contact forms, overload terminal numbering (1-3-5/2-4-6, 95-96, 97-98) and drive terminals (L1/L2/L3 in, U/V/W out). PDF export produces IEC-style ladder diagrams and field wiring drawings with title blocks.

Who is PickettPanel for?

Electrical apprentices and trades students preparing for practical assessments, instructors who want a live teaching aid for control circuits and fault finding, and panel builders who want to prove control logic before wiring.
