What is the NEC requirement for service splices according to Article 230?

The requirement outlined in Article 230 of the National Electrical Code (NEC) specifies that splices in service conductors must be both weatherproof and accessible for maintenance. This ensures that any connections made within the service entrance are protected from environmental factors, which could lead to degradation or failure, and it facilitates easy access for inspection, modification, or repairs as needed.

Weatherproof splices help to prevent moisture ingress, corrosion, and other forms of damage that could compromise the integrity of the electrical system. Accessibility is crucial because it allows for routine maintenance to be performed without disrupting the overall service or needing extensive repairs to access hidden or sealed connections. This emphasis on both safety and usability is fundamental in ensuring that electrical systems remain reliable and compliant with safety standards.

Other options do not meet the standards set by the NEC, as they may suggest neglecting essential safety practices and maintenance considerations that could lead to dangerous conditions in the event of a failure.
