How do you secure anode to the tank?

• A. Wire
• B. Bolt
• C. Clamp
• D. Tape

Answer: (A)

In a corrosion-protection setup, the sacrificial anode must be electrically bonded to the tank so the protective current can flow between them. A bonding conductor provides a continuous, low-resistance path that remains secure in outdoor and rugged conditions. A bonding wire is the standard method because it can be routed to the anode and tank, withstand weather, and be inspected or replaced as needed. Other methods like a bolt or clamp can loosen or fail to maintain a reliable electrical connection, and tape cannot conduct electricity, so it would prevent the protective current from flowing. That’s why using a wire to connect the anode to the tank is the correct approach.
