Attach the wire to each light fixture.
How to connect multiple low voltage wires to transformer. On one side often called input there is usually a white wire and a black wire to connect to the main power or line voltage coming from your home. Attach the two black wires from the transformer to the 120 VAC power supply wires. If you have a multi-tap transformer all you have to do is change to a higher tap at the transformer and the voltage will increase to the lamp.
In parallel the currents add at the same voltage. With your two 6 kV 30 mA outputs in series you would get 12 kV at 30 mA. The wire also needs to be rated for use inside a wall and being buried in insulation.
The other big voltage drop killer is that we typically tap into an existing outlet and the homeowner adds something to that circuit thus causing voltage drop. Measure the voltage at the first light using a voltmeter. Secondary phase-and-ground voltage with three coupling capacitor voltage transformers CCVTs connected phase-to-ground.
Many low voltage light fixtures use quick connectors to make this process simple. Twist together the kit wiring with the new wiring one lead to one lead to make a continuous length of wire. Tie these two terminals together with a jumper and tighten with the screwdriver.
You should have four bare and separated leads. Connect the 10-gauge main wires to the transformer by stripping off 34 in. A step-down transformer reduces the 110-120VAC line voltage down to 16-20-24 low-voltage for doorbell component compatibility.
For small control transformers there will. Hi I have a question about adding in more low voltage landscape wire to light up the other side of the house crossing my garage. I plan on slicing in.
