WireTutor is an interactive circuit simulator built for electrician apprentices. Drag components, connect wires with correct UK colours, and get instant safety feedback — before you ever touch a real cable.
WireTutor combines a realistic wiring environment with the kind of safety logic your college assessor would apply — so you learn the right habits from day one.
Place 11 UK electrical components — from MCBs to RCBOs — onto a canvas and connect them with colour-coded wires. Brown for live, blue for neutral, green-yellow for earth.
Not just "does the bulb light up?" — WireTutor checks if the live conductor is switched, detects short circuits, neutral switching, missing earth, and more.
Follow step-by-step exercises for one-way lighting, two-way lighting, radial socket, and ring final circuits. Each exercise checks your work against real UK wiring rules.
Toggle switches on and off and watch lamps respond in real time — but only when the circuit is correctly and safely wired. Unsafe circuits won't light up.
Every fault is explained in simple English, the way a good instructor would. "The switch is on the neutral conductor — this is unsafe. The switch must always interrupt the live."
WireTutor flags faults you'd fail an inspection for: earth used as current-carrying conductor, live connected directly to neutral, missing protective conductor, and more.
Three steps from blank canvas to a verified safe circuit
Pick from 11 real UK electrical components — supply, MCB, RCBO, switches, lamps, sockets, junction boxes, and more. Drop them anywhere on the grid.
Click a terminal to start a wire, click another to connect. Choose the correct UK wire colour: brown (live), blue (neutral), or green-yellow (earth).
Hit "Test Circuit" to get instant feedback. WireTutor tells you if the circuit is correct, incomplete, or unsafe — and explains exactly why in plain English.
