I would like to wire this setup so that the switch operates independent of the receptacle, so my plan is to run 12/2 from the junction box to the switch/recept combo, then 12/2 to the first light, and 12/2 to the second light. The first few went great because they only had one cable coming in (14 gauge black, white, and ground wires) and fit nicely in the junction box. Then came the light closest to the switch which has four cables -- I assume are one power and three feeding other lights (but may be two feeding other lights, one power, and one to the switch).Many wires does not mean it’s not safe, if it is connected properly and the box can handle the amps it is safe.
