Multi Stranded Wires for WAGO 221 Connectors
Yes, you can insert multi-stranded wires into a single slot of a WAGO 221 connector, but there are important considerations to ensure a safe and reliable connection:
-
Follow WAGO’s Guidelines: Each slot is typically designed for one wire. However, some WAGO connectors allow multiple fine-stranded wires in one slot, but only if they meet the cross-section limits specified in the datasheet.
-
Check Wire Size Compatibility: The WAGO 221 series supports solid, stranded, and fine-stranded wires with cross-sections ranging from 0.14 mm² to 6 mm² (26–10 AWG). If using multiple stranded wires, their combined cross-section must not exceed the connector’s rated capacity.
-
Pre-Twisting (if necessary): If inserting multiple fine-stranded wires into one slot, you might need to twist them together to ensure a secure grip and avoid loose strands.
-
Consider Using Ferrules: For fine-stranded wires, using ferrules can improve contact reliability, especially when inserting multiple strands into a single slot.
-
Use a Larger Connector if Needed: If connecting multiple conductors in a single slot is not ideal, consider using a larger WAGO connector with more terminals to accommodate individual wires separately.
Consulation :
Multiple wires in a Wago connector is not recommended. The clamp mechanism inside could clamp to one wire firmly and not the other one. This can lead to the lesser clamped wire able to pull out of the connector.
