Circuit Diagram

Live → MCB → Switch → Bulb → Neutral

Steps

1. 1 Place a Live (L) terminal and a Neutral (N) terminal on the canvas.
2. 2 Place an MCB to the right of the Live terminal.
3. 3 Place a Single-way Switch to the right of the MCB.
4. 4 Place a Bulb (E27) to the right of the Switch.
5. 5 Wire: Live → MCB → Switch → Bulb → Neutral.
6. 6 Press Run. Toggle the Switch to turn the bulb on and off.

Components Needed

Circuit Diagram

Live → MCB → Switch → Junction Box → Bulb A
                                        → Bulb B → Neutral

Steps

1. 1 Build the single-lamp circuit from Circuit 1.
2. 2 Add a Junction Box after the Switch.
3. 3 Place a second Bulb below the first.
4. 4 Wire the Junction Box output to both bulbs.
5. 5 Connect both Bulb Neutral ports back to the Neutral terminal.
6. 6 Press Run — both bulbs light at full brightness.
7. 7 Disconnect one bulb wire — the other stays on. That's parallel wiring.

Components Needed

Circuit Diagram

Live → MCB → SW1 COM
SW1 L1 ——→ SW2 L1 (strapping)
SW1 L2 ——→ SW2 L2 (strapping)
SW2 COM → Bulb → Neutral

Steps

1. 1 Place Live, Neutral, MCB, and a Bulb.
2. 2 Place two Two-way Switches between the MCB and the Bulb.
3. 3 Wire MCB → Switch 1 COM port.
4. 4 Wire Switch 1 L1 → Switch 2 L1 (first strapping wire).
5. 5 Wire Switch 1 L2 → Switch 2 L2 (second strapping wire).
6. 6 Wire Switch 2 COM → Bulb.
7. 7 Wire Bulb Neutral → Neutral terminal.
8. 8 Press Run. Toggle either switch — the bulb responds from both locations.

Components Needed

Circuit Diagram

Live → MCB → RCD (L-in→L-out) → Socket (L)
Neutral → RCD (N-in→N-out) → Socket (N)
Earth → Socket (E)

Steps

1. 1 Place Live, Neutral, and Earth terminals.
2. 2 Place an MCB and wire Live → MCB.
3. 3 Place an RCD. Wire MCB output → RCD L-in. Wire Neutral → RCD N-in.
4. 4 Place a 3-Pin Socket.
5. 5 Wire RCD L-out → Socket L.
6. 6 Wire RCD N-out → Socket N.
7. 7 Wire Earth terminal → Socket E.
8. 8 Press Run — the socket is live and protected by both the MCB and RCD.

Components Needed

Circuit Diagram

Live → MCB → Timer Switch → Bulb → Neutral

Steps

1. 1 Place Live, Neutral, MCB, a Timer Switch, and a Bulb.
2. 2 Wire: Live → MCB → Timer Switch (L-in) → Timer Switch (L-out) → Bulb → Neutral.
3. 3 Press Run. The circuit is live.
4. 4 Click the Timer Switch to simulate it reaching its ON trigger time — the bulb activates.
5. 5 Click again to simulate the OFF time — the bulb goes dark.

Components Needed

Circuit Diagram

Live → MCB → Dimmer Switch → Bulb → Neutral

Steps

1. 1 Place Live, Neutral, MCB, a Dimmer Switch, and a Bulb.
2. 2 Wire: Live → MCB → Dimmer (L-in) → Dimmer (L-out) → Bulb → Neutral.
3. 3 Press Run — the bulb is powered through the dimmer.
4. 4 Toggle the Dimmer to see the controlled state.

Components Needed

Circuit Diagram

Live → MCB → Push Button → Bell → Neutral

Steps

1. 1 Place Live, Neutral, MCB, a Push Button, and a Bell/Buzzer.
2. 2 Wire: Live → MCB → Push Button (L-in → L-out) → Bell (L) → Neutral (N).
3. 3 Press Run.
4. 4 Click and hold the Push Button — the Bell activates.
5. 5 Release the button — the Bell stops. That's a momentary circuit.

Components Needed

Circuit Diagram

Live → DB (L-in) → L1 → MCB1 → Switch → Bulb
                    → L2 → MCB2 → 3-Pin Socket
                    → L3 → MCB3 → Motor
Neutral → DB (N-in) → N1/N2 → (all returns)

Steps

1. 1 Place a Live terminal, Neutral terminal, and a Distribution Board.
2. 2 Wire: Live → DB L-in. Wire: Neutral → DB N-in.
3. 3 Circuit 1 (Lighting): DB L1 → MCB1 → Switch → Bulb → DB N1.
4. 4 Circuit 2 (Sockets): DB L2 → MCB2 → 3-Pin Socket (L) → DB N1.
5. 5 Circuit 3 (Motor): DB L3 → MCB3 → Motor (L) → DB N2.
6. 6 Press Run — all three circuits operate independently.
7. 7 Trip MCB2 — only the socket goes dead. Lighting and motor stay running.
