Wago Connector

What is a Wago Connector?

A Wago connector (named after the brand WAGO Connector, but now a generic term for lever-nut style connectors) is a wire joining device that electrically connects multiple wires together. Unlike traditional wire nuts that twist wires together, Wago connectors use spring-loaded clamps for quick, secure connections. In Elecplanner, the Wago connector component electrically joins multiple wires, determining the dominant electrical state and propagating it to all connected terminals. It’s perfect for splitting power lines, joining neutral wires, or creating common connection points.

When to Use Wago Connectors

Common Applications

• Joining neutrals: Connect neutral wires from multiple devices to a common neutral
• Splitting power: Distribute one power source to multiple destinations
• Creating junction points: Make accessible connection points in your circuit
• Wire consolidation: Combine multiple wires into one connection
• Testing points: Create convenient access points for circuit testing

Advantages Over Other Methods

• Cleaner than wire nuts: More compact and organized
• Easier to modify: Add or remove wires without affecting others
• Visual clarity: Clear representation of wire connections
• Professional appearance: Matches real-world installation practices
• Flexible: Configurable number of terminals

Adding a Wago Connector to Your Canvas

Step 1: Open the Component Library

1. Click the Components button in the sidebar
2. Open the Connections or Wiring category
3. Find the Wago Connector component

Step 2: Place on Canvas

1. Click and hold the Wago Connector icon
2. Drag it onto your canvas
3. Release to place it at the desired location
4. The connector will appear with 3 terminals by default

💡 Tip: Place Wago connectors at logical junction points in your circuit, such as where power splits to multiple devices or where multiple neutrals come together.

Moving and Positioning Wago Connectors

Moving a Wago Connector

1. Click and hold on the Wago connector
2. Drag it to a new location on your canvas
3. Release to place it
4. Connected wires will automatically adjust to follow the connector

Strategic Placement

• Near devices: Place close to devices that need connections
• At junction points: Where circuits branch or combine
• Accessible locations: Where you’d actually install a connector
• Logical grouping: Group connectors by function (all neutrals, all grounds, etc.)
• Inside junction boxes: Often placed conceptually within junction box components

Understanding Wago Terminals

Configurable Terminals

The Wago connector has a configurable number of terminals:

• Default: 3 terminals (T0, T1, T2)
• Adjustable: Can be increased or decreased based on your needs
• Labels: Each terminal is labeled (T0, T1, T2, … Tn)
• Tooltips: Hover over terminals to see their labels

How It Works Electrically

All terminals are electrically connected together inside the Wago connector.

The connector:

1. Examines the electrical state of all connected wires
2. Determines the dominant state based on priority rules
3. Propagates that dominant state to all terminals
4. Creates electrical continuity between all connected wires

State Priority (Highest to Lowest)

When multiple wires with different electrical states are connected:

1. HIGH (Highest priority) - Takes precedence over all other states
2. LOW - Takes precedence over GROUND and FLOATING
3. GROUND - Takes precedence over FLOATING
4. FLOATING (Lowest priority) - Default when no other states are present

Example:

• T0 connected to HIGH wire
• T1 connected to LOW wire
• T2 connected to FLOATING wire
• Result: All terminals become HIGH (highest priority)

Example 2:

• T0 connected to LOW wire
• T1 connected to GROUND wire
• T2 not connected
• Result: All terminals become LOW (higher priority than GROUND)

Editing Wago Connector Properties

Opening the Properties Panel

1. Click on the Wago connector to select it
2. The properties panel appears on the right side of the screen
3. Or double-click the connector to open properties

Configuring the Number of Terminals

The Number of entries property determines how many wires can connect to the Wago.

To change the number of terminals:

1. In the properties panel, find Number of entries
2. Enter the desired number (typically 2-8)
3. The connector will update to show the new number of terminals

💡 Choosing the Right Number:

• 2 terminals: Simple wire joining (two wires become one)
• 3 terminals: Most common - one input, two outputs (or vice versa)
• 4 terminals: Multiple device connections to one source
• 5+ terminals: Complex junction points, many-to-many connections

Best Practice: Use exactly the number of terminals you need. Don’t add extras - it makes your diagram harder to understand.

Labeling the Connector

Always label your Wago connectors to indicate their purpose:

• “Neutral Common” for joined neutrals
• “Living Room Power Split” for power distribution
• “Kitchen Ground” for ground connections
• “Phase Junction” for hot wire distribution

Clear labels make your electrical plan much easier to understand!

Wiring with Wago Connectors

Basic Wire Connection

Connecting wires to a Wago connector:

1. Select the Wire tool from the toolbar (or press W)
2. Click on a source terminal (from a device, panel, or another connector)
3. Click on a Wago connector terminal (T0, T1, T2, etc.)
4. Repeat to connect additional wires to other Wago terminals
5. All connected wires are now electrically joined

Reading Wire Flow

Input and Output are flexible - Wago connectors don’t have fixed inputs or outputs. However, for clarity:

Common Convention:

• T0: Typically the “input” or “source”
• T1, T2, T3, etc.: Typically “outputs” or “destinations”

But remember: Electricity flows both ways! The Wago simply joins all wires together.

Using Wago Connectors in Simulation Mode

Simulation Behavior

1. Click the Simulate button in the toolbar (or press S)
2. The Wago connector becomes “active”
3. It automatically determines the dominant electrical state
4. All terminals adopt and propagate that state
5. Wires connected to the Wago reflect the common state

Observing State Propagation

Test the dominant state logic:

1. Connect HIGH and LOW wires to different Wago terminals
2. Run simulation
3. Observe that all terminals become HIGH (highest priority)
4. This demonstrates how the state priority system works

Testing power distribution:

1. Connect power source to T0
2. Connect multiple devices to T1, T2, T3
3. Run simulation
4. All devices receive the same power state
5. Toggle the power source and watch all devices respond

Common Wago Connector Patterns

Pattern 1: Neutral Wire Junction

Device 1 Neutral → Wago T0
Device 2 Neutral → Wago T1
Device 3 Neutral → Wago T2
Main Neutral Bus → Wago T3

Result: All device neutrals connected to panel neutral bus

Very common for joining multiple device neutrals!

Pattern 2: Power Distribution (1-to-Many)

Circuit Breaker Output → Wago T0
Wago T1 → Switch 1
Wago T2 → Switch 2
Wago T3 → Switch 3

Result: One circuit breaker powers three switches

Great for distributing power to multiple circuits!

Pattern 3: Ground Wire Collection

Outlet 1 Ground → Wago T0
Outlet 2 Ground → Wago T1
Outlet 3 Ground → Wago T2
Ground Bus → Wago T3

Result: All outlets share common ground connection

Essential for proper grounding!

Pattern 4: Many-to-One Junction

Device A → Wago T0
Device B → Wago T1
Device C → Wago T2
Single Wire to Destination → Wago T3

Result: Multiple sources combined into one output

Less common, but useful for specific scenarios!

Pattern 5: Series Circuit Simplification

Before (messy):
Source → Device 1 → Device 2 → Device 3 → Destination

After (clean):
Source → Wago T0
Wago T1 → Device 1
Wago T2 → Device 2
Wago T3 → Device 3
Wago T4 → Destination

Result: Cleaner, more organized wiring diagram

Best Practices

Connector Sizing

1. Count connections first: Determine exactly how many wires need to connect
2. Add one for flexibility: Include one extra terminal for future needs (optional)
3. Don’t oversize: Too many unused terminals create confusion
4. Typical range: Most applications use 3-5 terminals

Organization and Labeling

1. Clear labels: Always label what the Wago connects (e.g., “Kitchen Neutrals”)
2. Group by type: Keep neutrals, hots, and grounds separate
3. Logical placement: Position near related devices or in junction boxes
4. Color coordination: Use wire colors consistently (red=hot, blue=neutral, green=ground)

When to Use Wago vs. Alternatives

Use Wago Connector when:

• Multiple wires need to connect at one point
• You want clean, organized junction points
• Future modifications are likely
• Professional appearance is important

Use Direct Wiring when:

• Simple point-to-point connections
• No branching or joining needed
• Very short wire runs

Use Junction Box when:

• You need a physical enclosure
• Multiple Wagos will be grouped together
• Code requires accessible splice points
• Organizing complex wiring scenarios

Placement Strategy

1. Inside junction boxes: Wago connectors are often placed conceptually within junction box components
2. Near devices: Place close to the devices being connected
3. Accessible locations: Where you’d actually be able to install them
4. Avoid crowding: Don’t place too many connectors in one area
5. Clear wire paths: Position to minimize wire crossing and clutter

Troubleshooting

Unexpected Electrical State

Problem: Wago connector shows unexpected state in simulation

Check:

• What states are connected to each terminal?
• Is there a HIGH connection (overrides everything)?
• Are all expected wires actually connected?
• Review the state priority rules (HIGH > LOW > GROUND > FLOATING)

Solution:

• Verify wire connections to each terminal
• Check source devices (breakers, switches) are in expected states
• Remember: HIGH always dominates!

Devices Not Responding

Problem: Devices connected through Wago don’t work

Check:

• Is power actually reaching the Wago T0 (or input terminal)?
• Are all output terminals actually wired to devices?
• Is the circuit breaker ON?
• Is the complete circuit path established?

Solution:

• Trace wires from source → Wago → device → neutral → ground
• Verify no breaks in the circuit
• Check that all necessary terminals are connected

Wago Won’t Accept More Wires

Problem: Need to connect more wires than available terminals

Solution:

• Increase the “Number of entries” in properties
• Or use multiple Wagos (one for some connections, another for others)
• Or cascade Wagos (connect Wago output to another Wago input)

Unclear Wire Organization

Problem: Too many Wagos or confusing connections

Solution:

• Label every Wago clearly
• Use consistent terminal numbering (T0 = input, others = outputs)
• Group related Wagos together visually
• Consider using junction boxes to contain multiple Wagos
• Reduce complexity by consolidating connections

Advanced Techniques

Cascading Wagos

Connect multiple Wagos for complex distributions:

Main Power → Wago A (T0)
Wago A (T1) → Device 1
Wago A (T2) → Device 2
Wago A (T3) → Wago B (T0)
Wago B (T1) → Device 3
Wago B (T2) → Device 4

This creates a hierarchical distribution tree!

Wago + Junction Box Combination

Professional approach:

1. Place a Junction Box on your canvas
2. Position multiple Wago Connectors inside (conceptually)
3. Group related Wagos:
   • One for all hot wires
   • One for all neutrals
   • One for all grounds
4. This represents a real-world splice box with multiple connections

Color-Coded Wire Management

Maintain visual clarity:

1. Red wires → Hot/Phase Wagos
2. Blue wires → Neutral Wagos
3. Green wires → Ground Wagos
4. Never mix wire types in one Wago
5. Label Wagos by color/purpose

Star vs. Daisy-Chain Topology

Star Topology (using Wagos):

• Central Wago with all devices radiating out
• Easy to add/remove devices
• Each device has independent connection
• Preferred for professional installations

Daisy-Chain (not using Wagos):

• Devices connected in series
• Simpler for few devices
• One break affects all downstream
• Traditional residential wiring
