When are service-entrance conductors permitted to be spliced?

Service-entrance conductors are permitted to be spliced at any time, including during initial installation and subsequent modifications, as long as proper connection methods are utilized. This aligns with the requirements of the National Electrical Code (NEC), which emphasizes that splices must be made in accordance with manufacturer instructions and meet the necessary standards for safety and reliability.

It is crucial that the splicing methods used ensure adequate protection against electrical hazards and maintain the integrity of the circuit. Properly executed splices will allow for continuity of electrical service without compromising safety. This flexibility in splicing during both installation and maintenance allows electricians to adapt the electrical system as necessary while adhering to code requirements.

While the other options may touch on aspects of safety or qualifications, they do not accurately reflect the NEC's stance on the flexibility provided for splicing service-entrance conductors.
