If you start to get close to the transformers capacity you may notice a drop in brightness of your lights.
Landscape lighting cable length. Total watts on low voltage wire length of wire run in feet wire size constant listed in chart below VOLTAGE DROP. WATTS WIRE RUN LENGTH CONSTANT VOLTAGE DROP. Over 200 watts you should use a 12 gauge sized wire.
-In trench below minimum 2 thick concrete - 6 inches. Use heavier gauge cable. 40 x 125.
4 7 watt lights x 125 35 watts. Use this voltage drop equation to figure out how many volts your wire will lose over a distance. Keep in mind that wattage requirements are bare minimum.
-Under a building - In raceway only. Enter the desired footage in the QTY box. Landscape Lighting Cable is sunlight-resistant suitable for direct burial and for use at temperatures between -20C and 60C.
Step 1 - Input the voltage of your existing or new power transformer11 12 13 14 15 16 17 18 19 20 21 22 23 or 24 volts Step 2 - Input the total length of your wire from the transformer to each branch circuit Step 3 - Plug in the total wattage of your individual branch circuits Step 4 - Select a drop multiplier. 4 track section may be easily cut to desired length. From table 430-150 they draw 40 amps 14 amps and 3 amps respectively.
Please call for longer put ups. Cable length is 100 inches which can satisfy your long-distance installation requirements for lighting equipment HIGHLY EFFICIENT. Voltage Drop Equation For Landscape Lighting.
