ECN Forum Forums General Topics of the Trade General Discussion Area Ran 14/2 wire on 20 amp circuit

I added a chandelier in a dining room between 2 can lights.I tapped off of the can lights with 14/2 romex to the chandelier. The can lights were ran in 12/2 and the circuit is on a 20 amp breaker. I believe this is against code, should I be worried that the 14/2 could overheat and cause a fire???? Because I'm a bit worried that this could be a real issue.
