In a panel design, solid conductors are often routed:

• A. Through flexible conduits
• B. Directly to terminal blocks
• C. Inside flexible hoses
• D. Wrapped around moving parts

Answer: (B)

When wiring inside a panel, solid conductors are routed directly to terminal blocks because they provide clean, secure terminations without extra hardware. The stiffness of solid wire lets you land it neatly under a screw or clamp and keep the connection stable against vibration and movement. This simplifies routing, inspection, and maintenance, and it avoids the need for ferrules or additional connectors that would be more common with stranded conductors. Routing through flexible conduits or hoses inside the panel would add bulk and complexity, while wrapping around moving parts can cause wear or loosening of connections. Directly terminating solid conductors at terminal blocks is the straightforward, reliable approach for fixed panel wiring.
