DExtend the length of a circuit with twist-on connectors if in an enclosure and wrapped securely with insulating tape.
AI Explanation
The correct answer is C) Connect a flexible cord or cable to a fitting with so that tension is not transmitted to joints or terminal screws. This is correct because the electrical engineering regulations in the CFR (Code of Federal Regulations) require that connections in electrical systems are made in a way that prevents strain or tension from being transmitted to the connection points. Allowing tension on the connection can lead to loosening and potential failure of the circuit. Option C properly addresses this requirement, while the other options either do not fully meet the regulations or involve techniques that are not permitted.
