Likewise, people ask, are wire connectors color coded?
Twist-on wire connectors are commonly color-coded to indicate the connector size and, hence, their capacity.
Should you twist wires before wire nut?
With the exception of stranded wire, which we'll talk about below, it's important to make sure the ends of all wires are lined up before twisting on the wire nut connector. You don't have to twist the wires together before you screw on the connector.
