Comparative Criteria for Connectors
Ease of Use
Understanding how to operate these connectors is straightforward. All connectors work with both solid core and stranded wires, so there's no concern about conductor type. They feature information on allowed cross-sections, voltage, and current. Most provide details on how much insulation to remove, though a couple lack this information and have poorly performing levers, resulting in a point deduction for them. Otherwise, the connectors offer comprehensive information, meriting them the highest marks in this category.
Extra Features
Test points are available on most connectors, allowing easier troubleshooting of electrical systems. Additionally, many connectors can be secured using screws, either via housings designed with extra holes or separate adapters. Connectors with these features earn additional points, as they enhance convenience and reliability.
Size and Form Factor
Connectors mimicking the size of the Wago 221 are seen as excellent choices due to their compact form. Others that are slightly bulkier resemble older versions of Wago connectors. This earns them a good rating but not the top score.
Price Point Analysis
The price per piece reveals the ViD connector to be the winner. Interestingly, genuine 2, 3, or 5 pole Wago connectors are cheaper than most knock-offs. Calculating cost per connection point shows ViD and Wago as top choices, resulting in ViD receiving the highest score, while others receive lower ratings.
Pull Test Results
During pull tests, most connectors required 20 to 30 kg of force for wire removal, which was rated as good. Notably, two connectors demonstrated exceptional gripping power deserving of the highest score. Conversely, one connector performed poorly, allowing wires to be removed by hand, warranting a lower score.
Resistance and Safety Tests
High resistance in a connector can lead to power loss, deformation, sparks, and potentially fires. Resistance was measured by assessing the voltage drop at 20A through the connector. By performing calculations to isolate connector resistance, results were plotted, highlighting which connectors maintained safer resistance levels.
Mechanical Lever Mechanism
When it comes to various Wago Knock-Offs, the predominant feature they share is the mechanical lever mechanism. This mechanism secures an electrical conductor by pushing it onto a bus bar, ensuring a firm connection. The action typically involves a spring principle, which allows flexibility for different wire types, like solid core and stranded wires.
Among the connectors evaluated, most utilized this lever system, though one unique model replaced it with a slider mechanism. This particular slider design required an additional tool, which comes included with the connectors. Despite these variations in design, each connector was tested for its ease of use and intuitiveness, not requiring you to exert more force than necessary for operation.
A consistent advantage across these connectors is their reusability due to the spring mechanism. You can repeatedly use them without losing their gripping efficiency. In testing, the old criteria list—such as fast usage or flammability—was revised, acknowledging their consistent performance in these aspects. Instead, new evaluation categories, like additional features and certifications, are prioritized.
Connectors often display essential information directly on their surfaces, such as the permitted cross section, applied voltage, and current. Most also detail the required amount of wire insulation removal, though a couple lacked this guidance, affecting their ratings. As you utilize these connectors, this transparency makes the process straightforward and efficient. Most models presented superb usability, which earned them top scores in functionality.
Another critical feature to consider is the testing access point, which facilitates troubleshooting electrical circuits.
