Fast answer

Confirm conductor type, conductor cross-section, positions, voltage and current requirement, installation environment and exact-model document scope. Follow the stripping and operating instructions for the selected model, then approve a sample in the intended enclosure or equipment.

1. Identify the conductor type

Solid, stranded and fine-stranded conductors behave differently during insertion and clamping. Ferrules also change the finished conductor geometry. Record the conductor construction and whether a ferrule will be used before selecting the model.

Conductor informationWhat to specifyWhat to verify
ConstructionSolid, stranded or fine-strandedExact model accepts that conductor type
Sizemm² and AWG when availableFalls inside the model’s permitted range
TerminationBare conductor or ferrulePermitted preparation and finished diameter
MaterialNormally copper; state alternatives explicitlyModel documentation and application suitability

2. Choose the number and direction of positions

The number of positions must match the circuit connection plan. Also check whether conductors enter from the same side, opposite sides or another model-specific direction. A compact inline connection and a multi-port junction solve different layout problems even when both have three levers.

3. Review voltage, current and temperature together

Use the circuit requirement and conductor size to review the exact model rating. Do not assume that every connector in the same visual family carries the same voltage, current or temperature value. Consider enclosure temperature, adjacent heat sources and the applicable standard or installation rule for the target market.

Buyer rule: Request the rating row and document reference for the exact ordering code. A family photograph or generic “UL/TUV available” statement is not enough.

4. Check preparation and operation

Stripping length, insertion depth and lever operation are model-specific. Use the marking or instruction for the selected connector. After insertion, inspect the conductor position and perform the sample checks appropriate to the intended application.

  • Strip the conductor to the specified length without damaged strands.
  • Open and close the lever through its intended travel.
  • Insert the conductor fully; no unintended bare copper should remain exposed.
  • Confirm the conductor is held after normal installation handling.
  • Verify the connector fits the enclosure and permits the required bend radius.

5. Match the installation environment

Identify whether the connector will be used in a junction box, luminaire, control panel, equipment assembly or protected outdoor junction. An open lever connector is normally part of a larger installation and should not be treated as a waterproof enclosure unless the exact assembly is designed and documented for that purpose.

6. Confirm certificate and market scope by model

CE, TUV and UL documentation is available for selected WIRIX models. If a customer or project requires one of these documents, provide the exact model, destination market and required standard. Confirm that the applicable declaration, certificate or report covers the model or documented family and the relevant rating. Do not transfer a document claim from a similar housing to an unlisted configuration.

Common selection mistakes

Choosing by appearance

Similar housings can have different conductor ranges, ratings or document coverage.

Ignoring conductor preparation

A fine-stranded conductor, ferrule and solid wire are not interchangeable assumptions.

Using the family rating

Ratings and certifications must be tied to the exact model.

Skipping the enclosure check

Connector size, wire direction and bend radius can prevent a practical installation.

Frequently asked questions

Are all WIRIX models covered by CE, TUV and UL documentation?

No. Document availability and scope vary by model. Confirm the exact ordering code, applicable rating and destination market before relying on a declaration, certificate or report.

Can a lever connector accept solid and stranded wire?

Many lever designs support more than one conductor type, but the exact permitted range and preparation must be confirmed for the selected model.

Does the number of levers equal the number of circuits?

It shows the available conductor positions, but the circuit layout and intended circuit use must still be confirmed.

Is a lever connector waterproof?

Not by default. Use a documented protected connector or a suitable enclosure when moisture protection is required.
