One strand of the copper wire in the new chandelier I bought was snapped. Just one! Is it still going to work??

We have no idea, return it and get a new fixture.

One strand, or one conductor?
What does "snapped" mean? Completely broken/cut?

I agree with TK. Return it.
Big box stores will take anything back, even if you broke it.

One strand out of the bundle of the copper/ground wire snapped. If this will still work, I would rather not go through the hassle of shipping it back since it was purchased from NY. Thanks

Now that we know it is only one strand, it will work fine.
