Which kitchen faucet needs to be grounded?

A kitchen faucet in most cases does not need to be grounded only a faucet with the nickel finish, this finish is also called stainless steel-LOOK, Nickel-Mat and Platinum-Mat. Pit corrosion can occur on the faucet (often the spout / neck of the faucet). The nickel finish has a protective layer that prevents corrosion from developing on the faucet. Once the protective layer is damaged, it is possible when an electric charge from running water passes through the faucet pit corrosion can occur. In this case, you should place an additional ground wire at the faucet.
