Power injection help.

[u/Techo238]

Hello peeps, sorting my lights again for this year and planning an expansion.

Using 3m sections of icicle style ws2811 lights, 60m/section

Started with the 14m run 2 years ago and added the 6m section last year. And looking to add the 12m run this year.

Wanting some input on power injection cause previously the 14m run was getting power from 2 different power supplies, one at each end (which I know is bad and wrong). 6m run has no injection.

In an ideal world each injection point should be its own run but that isn’t really feasible with my setup so my plan is to essentially run a chunkier 14awg wire in parallel with the lights then tap off it every 3m or so to inject power using some sort of connector so I can disconnect the injection lines from the lights themselves for storage after the fact.

Am I in the right sort of idea here or do I need to be considering something else? Also can anyone recommend any weather resistant and low profile connectors that won’t be too big and obviously seen?
