About Wire Connections
The quick connectors which accompany most outdoor low voltage fixtures are designed such that moisture gets in the wire. First thing we do on a repair is remove the connectors, strip the wire back 1 1/2 inches. Twist a solid connection and use outdoor wire nuts. If the wire is in an area where connections are challenged, then take time to tape it well. You will be surprised how a really good connections can affect bulb life. Even LEDs.

Wire Connections Make the Difference
Landscape light wire sits in moisture. Quick connects do not last. The connection area receives moisture, connection becomes poor. The new mechanical wire strippers allow the following connection be easy and fast. If it seems like over kill; at least you know your connections are strong and will last.



Remove quick connector


Cutting off the crimp connector.

This connector came on the fixture. It uses piercing the landscape wire to hit the coper braid in the wire. it relies on a thin tooth to enter the wire where the copper connector is. Overall a connection is made.

The hand strip and hand twist is many times more robust and reliable.

Strip twist, and tape or water proof wire nut connectors. Best to strip at least 1 1/2 inch. Twist the wires neat and tight as possible. Tape real well. With wire nuts, snip the twisted copper to length.




New style wire stripper makes the work of stripping heavy wire easier.
The unit works well on larger wire, but presents issues when attempting to strip stranded wire 22 gauge and smaller.
Most fixtures connection wire is a little thin for this size stripper.

Twist wire clockwise.

Twist individually before connecting with another wire.

Twisted together, this make for a tough connection. Wire laid out in garden areas gets some abuse from general landscape maintenance.

Using wire nuts, snip twisted connection to length for wire nut. Use the hand stripped, hand twisted connections for a robust install. Wire nuts don't twist the wire properly by them self. The procedure shown here will save lots of maintenance time in future.

Best light output from your installation of outdoor lighting, depends on strong and reliable connections.

Your low voltage landscape wire lays in the ground, where moisture collects.
Far better than the quick connects; better connection that will hold up over time.
