Hello,

I was trying to install a light fixture and when I was done connecting the wires, I lifted the fixture towards the ceiling to mount it and there was a spark and caused a black mark on the ceiling. Would that cause the breaker to trip? And should I be concerned about the wiring causing a fire?

What should I do?

No it wouldn't necessarily trip the breaker... it doesn't take much power to cause a spark.

But I would thoroughly check your wiring! It shouldn't have sparked at all. Is the wiring really old?

TURN THE BREAKER OFF.
Then remove the light fixture and check ALL the wiring in the box. Look for burn marks and nicks. Obviously something shorted so there is definitely a damaged wire in there somewhere.

Reno, see the link in my sig line.
