Bonded clamps are used for support when installing which type of tubing?

• A. Metal tubing
• B. Wiring
• C. Both metal tubing and wiring
• D. Neither

Answer: (A)

Bonded clamps are used where metal tubing carries the electrical ground, because they provide a reliable bonding path along the run while also offering mechanical support. Metal tubing (such as conduit or metal piping) forms part of the grounding path, so attaching a bonded clamp and tying it into the grounding conductor keeps the entire system at the same ground potential. Wiring, on the other hand, is insulated and does not rely on the tubing for grounding, so bonding clamps aren’t used for supporting wiring.
