How many wires are placed in each hole of the scotch locks?

The correct answer indicates that only one wire is placed in each hole of the scotch locks. Scotch locks, also known as butt connectors or insulation displacement connectors, are designed to create a secure electrical connection between two wires. Each connector is intended to accommodate a single wire in each of its holes to ensure a proper connection without risk of interference from additional wires.

Placing only one wire per hole helps in achieving a solid electrical contact and minimizes the possibility of shorts, which can occur if multiple wires are forced into a single connector. When used correctly, scotch locks facilitate reliable connections for various applications, including telecommunications and other electrical systems, adhering to safety standards and operational efficiency.

While the other choices suggest placing multiple wires in each hole, this practice can compromise the functionality and reliability of the connection. Using more than one wire can lead to inadequate contact, increased resistance, and potential failure of electrical connections.
