Why do kitchen sinks need to be grounded?

Kitchen sinks need to be grounded primarily for safety reasons. Grounding helps prevent electrical shock by directing any stray electrical currents safely into the ground, reducing the risk of electrocution if there is a fault in electrical appliances or wiring. Additionally, grounding can help protect sensitive electronic devices and appliances connected to the kitchen's electrical system. This is especially important in kitchens where water and electricity can come into contact.
