Wiring diagrams for longer run lengths
To power more than one roll of tape, we recommend using one of the following methods of wiring:
1) Run two power leads to feed into the controller (RGB/TW) or power supply (Single Color).
2) Power the run length from both ends.
3) Split the power feed and splice it to both runs from the middle. For more than two runs of tape, repeat the process.
For reference, this link gives a voltage drop table for 12V and 24V installations.
