Same series 2 lights on 2 separate switch.

Hello,

Working on installing light fixtures in my basement bedroom.
-Power source goes into first switch
-from that switch I have one line running to the ceiling light and the other line runs to another switch across the room for a different light.
- when the switches are ON I tested the black hot wire and both light boxes had power.
-once I install the fixtures and turn on the power it trips the breaker.

Please help.

Are you installing 3 way switches? Did you run 14/3 cable to switches? Post pictures of what you have done.

At the first switch do you have:
  • Power in black and power to switch #2 black to a black pigtail.
  • Black pigtail to one side of the switch.
  • Black to light #1 to other side of switch
  • All whites connected only to each other
  • Grounds per code.

At switch #2:
  • All whites connected only to each other.
  • Black power in to one side of the switch.
  • Black out to light to other side of the switch.
  • Grounds per code.

Welcome to the forums.

If both lines sitting there with nothing connected are fine and only become shorted with the light fixtures attached..... you have a shorted light fixture. Using the switches, or attaching one fixture at a time, you can determine which fixture is bad.

Yes that is now I wired it. 14-2 wire. From the breaker the series contains 4 outlets that continues into the switch box from that switch box I have one line that goes to the light box and the other line goes to another switch in the closet and ends with closet light. Like I mentioned before before the fixtures are installed i have hot power running to both fixtures but when I install the fixtures it trips the breaker. I tried different fixtures and switches and still tripped breaker. Really confused what I'm doing wrong. Must be grounded somewhere I don't notice.

At the fixtures you should have a white, black and a ground wire. It should be as basic as white to white, black to black and ground to ground.

That shouldn't create any shorts.
