Which option correctly identifies a bare copper conductor tie?

• A. Aluminum tie, insulated
• B. Copper tie, bare, soft annealed
• C. Aluminum tie, insulated, preformed
• D. Copper tie, bare, hard annealed

Answer: (B)

When tying bare copper conductors, you want a tie made from copper (not aluminum), that is bare (no insulation), and soft annealed so it’s ductile enough to wrap around the conductor without cracking. A copper tie that is bare and soft annealed fits these needs perfectly, providing the necessary pliability to form a secure wrap around the bare copper conductor. The other options fail because they use the wrong material (aluminum), apply insulation to a bare conductor, or use hard annealed copper which is too stiff to form properly.
