Installing a light fixture - what should we do with ground wire?
So a friend asked me to helped her out in their new home. So she had a light fixture she wants to install on the ceiling of the living room. However we don not see any ground wire that can be attached to the fixture's ground wire. This new house they bought is kinda old and the box in the ceiling only has two wires (white and black). The ground wire of the old house' fixture is wrapped around its chain. So what shall we do? Leave the ground wire or we wrap something around it?
