Power injection, just a quick question this time....

It depends on how thick the wire going to the start of the prop is.
If you had a heavy cable going to the prop, you could branch out from there. I did this with the pixel strip on my gutters.
Keep in mind that the single cable (to the prop) has to carry the load for all of the prop, no just the first part.

A lot depends on the total power being drawn and the size of the cables.
I run only 4 wires from my power supply to my mega tree injection points and split off at the bottom of each string, but the cables I run are heavy enough to carry the full load for the total of what is being drawn.
So as an example, I have 4 strings of 75 pixels 5v, theoretically I would draw 4.5 amps per string or 18 amps total on full white.
So I would use 20 amp wire and split it off at each string.
Obviously this is more helpful on yard props such as my spiral trees, where they are only 20 pixels high, so I inject the whole row of them with 1 main wire.
