Solder your wires before you put on the gel filled connectors.
Does polarity matter in landscape lighting. Polarity must be strictly maintained at each connection and at the transformer otherwise a. You can easily insert the wires when the transformer is on the ground. You would be shocked at how many designers skip this critical step Their design of the wiring plan ASSUMES a voltage output from the transformer.
Low voltage wire does not have polarity it does not matter which of the two wire connects to the Common Terminal and which to the Voltage Terminal as long as one wire goes to each. If you use 12V AC to power up LED lights you will see a comparatively dimmer glow. Well not quite.
Low voltage landscape cable runs on 12v and will not shock you and the wire does not have polarity it does not matter which wire connects to which. It is easier to see and insert the wires into their terminals when the transformer is lying on the ground. And in this section we gathered the info to let you know which one is best for you.
When you screw a light bulb into a socket the electricity is intended to flow into the light bulb from the button on the bottom of the socket. In regards to the importance of polarity of AC. I recently purchased 15 LED landscape lights the recommended 300 watt transformer and 150 ft of 12g wire.
There are major differences in outcomes when you accomplish your landscape lighting with 12V AC and 12V DC individually. However with lamps polarity is important. For low voltage lighting it doesnt matter- just forget about it--Tom Gauldin Raleigh NC.
Does polarity matter with LED lights. If you are installing a hub system connect your cable run to the hub and your fixtures wires to the hub wires. Another method that is not recommended is the loop or lollipop which is basically a daisy chain with the wire run from the last fixture looped back to the first fixture or transformer tap.
