What should be checked regarding terminal strips during an aircraft electrical system inspection?

The most critical aspect to check regarding terminal strips during an aircraft electrical system inspection is whether the studs are anchored against rotation. Terminal strips are designed to connect various electrical components, and the studs must be securely fastened to maintain a reliable connection. If the studs were painted, it could interfere with the electrical contact and possibly lead to poor conductivity. Ensuring the studs are properly anchored prevents any movement that could cause loosening, overheating, or ultimately failure in the electrical system.

Painted studs, while perhaps an aesthetic consideration, can lead to significant electrical problems by insulating the connection instead of facilitating it, making it the less suitable choice in an inspection context. Evaluating the integrity and security of the connection at the terminal strip is paramount to ensure the aircraft's electrical system functions properly and safely during operation.
