According to code, how are service entrance conductors spliced or tapped?

Service entrance conductors must be spliced or tapped using reliable mechanical connections, which can include methods such as clamping or bolting. This is required to ensure that the connections provide a secure and electrically conductive path while also allowing for sufficient mechanical strength to withstand potential stresses.

Mechanical connections are preferred in this context because they facilitate testing and maintenance, and they help ensure that connections can safely carry the expected load without the risks associated with other methods, such as soldering, which might not provide the necessary mechanical strength or reliability in high-current situations.

Connector types and methods are also vital to maintain safety and efficacy in electrical systems, as outlined in the National Electrical Code, to prevent issues such as overheating or failure due to poor contact. Therefore, splicing or tapping with connectors that are clamp or bolted provides both electrical continuity and mechanical integrity in service entrance systems, conforming to industry standards and practices.
