How does Article 314 handle splices within boxes?

Article 314 of the National Electrical Code (NEC) addresses the installation of electrical boxes, including the handling of splices within those boxes. The requirement that splices be made in a manner that maintains accessibility and complies with volume requirements is crucial for several reasons.

Accessibility is important because, in the event of a malfunction or need for modification, the splices need to be reachable without extensive work. This requirement ensures that electricians can service the connections without invasive work, promoting safety and functionality.

Complying with volume requirements is equally essential. Each electrical box has specific size limitations based on the number of conductors and fittings it contains. Making splices within these boxes must adhere to these volume calculations to ensure adequate space for heat dissipation and to prevent overcrowding, which can lead to overheating and potential fire hazards.

By mandating these conditions, the code aims to enhance safety, ease of maintenance, and overall reliability of electrical systems. Thus, option B accurately captures the intent of the NEC regarding splices in boxes, reflecting best practices in electrical work.
