Power Bench
A full electrical workbench in your browser.
Build circuits by placing components on an advanced electrical training board, drawing conductors, and creating a live schematic as you work. Energize the completed system, use electrical test instruments to take measurements, introduce common faults, and practice systematic troubleshooting. Circuit behavior, schematic conditions, and instrument readings update in real time based on the actual circuit you built.
Build
Build electrical systems from the ground up.
Start with a blank workspace. Place the components, draw the conductors, make the connections, and build the circuit yourself. From basic electrical fundamentals to three-phase power and motor controls, TradeBuilt™ gives you an open workspace to put electrical theory into practice.
- Build AC and DC, single-phase, split-phase, and three-phase systems
- Work with power sources, transformers, wiring, grounding, protection, switches, relays, contactors, controls, motors, loads, receptacles, and more
- Build everything from basic series and parallel circuits to transformer systems, motor controls, switching logic, and multi-phase circuits
- Build control circuits with plug-in ice cube relays and on-delay and off-delay timing relays
- Mark up drawings with text labels, comments, arrows, highlights, and wire numbers
- Switch between Visual and Schematic views to read the same circuit as the real hardware or as ANSI schematic symbols
- Energize what you build and see the system respond to the connections you made
Simulate
A simulation engine built to understand the circuit, not just animate it.
Behind every connection is a live electrical solver calculating how the system you built actually behaves. Change the wiring, source, load, control, operating condition, or fault and the electrical conditions change with it.
- Voltage, current, resistance, power, impedance, reactance, power factor, and phase relationships are calculated from the circuit
- Build and explore AC and DC systems including single-phase, split-phase, wye, delta, and high-leg delta power
- Transformers respond to turns ratio, loading, taps, grounding, faults, and reflected impedance
- Motors respond to starting current, phase sequence, and locked-rotor conditions, with simplified phase-loss and reduced-voltage behavior
- Switches and pushbuttons are operated by hand, while relay, contactor, and timer coils operate their contacts and interlocks from the control circuit you wire
- Breakers, fuses, and GFCIs respond to the electrical conditions they actually see
- Turn on Component Data to see live readings on every part while the circuit runs
- Follow electron flow at the solved current’s direction and speed, and use Energized Colors to identify conductors carrying voltage
- Adjust each source’s available fault current to see voltage sag under load and source-limited current during a short
- Connect the equipment grounding conductor from frame to earth ground so frame faults trip protection instead of leaving the frame energized
- Watch lamps and heating elements glow in proportion to the power they receive
Measure
Real instruments. Readings from the circuit you actually built.
Testing is part of the learning process. Take instruments out of the virtual tool bag, place them on the circuit, and use the measurements to understand what is happening. The readings aren’t predetermined, they come directly from the circuit being solved.
- Measure AC and DC voltage, AC current, resistance, and capacitance with the digital multimeter
- Clamp a conductor to measure current and capture motor inrush
- Check energized conductors and equipment with the non-contact voltage tester
- Test receptacle wiring and GFCI operation with the plug-in receptacle tester
- Measure resistance through all paths between the probes, including parallel paths, and see O.L. when no path exists
- Get a warning to connect the meter in series when measuring across a component on the current range
- Use the technician’s notepad to write down readings and complete checklists
- Change the circuit and the measurements change with it
Troubleshoot
Break it on purpose. Find it with a meter.
Turn a working circuit into a troubleshooting problem. Introduce faults directly into components, energize the system, observe what changed, take measurements, isolate the problem, and diagnose the fault from the circuit’s behavior.
- Create open, shorted, loose, and high-resistance conditions
- Troubleshoot ground faults, winding faults, weak capacitors, locked rotors, and failed coils
- Diagnose welded, stuck, open, and high-resistance switching contacts
- Create transformer primary, secondary, and grounding faults
- Find loose terminations that pass continuity tests by measuring their voltage drop under load
- Watch overloaded motor windings smoke and burn with missing, oversized, or failed protection, while correct protection opens first
- Watch protection respond to the electrical conditions created by the fault
