Pluggable terminal connectors for easy and reliable wire connections. But there are a few common mistakes people make when using them. Understanding these blunders can help prevent you from running into issues and keep your connections secure.
Don’t overtighten screws
One error is tightening the screws that secure the wires too much. If it’s screwed on too snugly, it might damage the internal wire. This can result in a poor connection, and sparks that can ignite a
In order to avoid doing so, only attach the screws enough that they hold the wire in place. When you make contact, you should feel the wire reach the inside part of the connector, but there’s no need to apply a lot of force. If you’re having difficulty tightening, see if the wire is prepped properly.
Don't Mix Wire Sizes
Another error is combining wires of different gauges in a single connection. Each connector is for a specific size of wire, and mixing them can result in bad connections. It may not connect with smaller wires, which may cause trouble.
To circumvent this, pair the wire size to the appropriate connector. Many din rail terminal connectors list on their label what sizes they can handle. If you want to join different sizes, simply connect with the appropriate conductor.
Prepare Wires Properly
In some cases, the wires are not prepared before they are inserted into the connector. When wires are not prepared in advance, they may not make good contact, which can be dangerous.
Before inserting wires, strip off enough insulation to expose the wire inside. Clean and straighten the wire, and then tighten it into the pluggable terminal block connector.
Match Connectors to Wire Size
Another common blunder is to use an improper connector inappropriate to the size of wire. If the plug doesn’t fit the wire, it’s going to give you trouble.
Avoid this by checking the label on the connector to ensure it’s the right size for your wire. If you don’t know what to use, ask someone who does. The right pluggable terminal connector will help keep everything safe.
Double-Check Connections
Finally, a lot of people forget to double-check their connections before plugging in the power. It is a good idea to look at each connection to ensure that the wires are tight and properly connected.
Flow Through is connected, but don't power it up until you've checked the links. Lightly tug on the leads to determine if they are tight. If there are any wires that feel shaky or look worn, power down and re-check.
