What standard must all electrical wiring for an on-site sewage disposal system comply with?

All electrical wiring for an on-site sewage disposal system must comply with the National Electrical Code (NEC). The NEC sets the foundational standards and safety requirements for the installation and maintenance of electrical systems and wiring in residential and commercial buildings, including those that serve sewage disposal systems. Compliance with this code ensures that the wiring is safe from fire hazards and electrical shocks, which is particularly important in potentially damp locations where sewage systems are located. The NEC is recognized at the national level and provides guidelines that help protect both the operation of the sewage system and the safety of individuals who may come into contact with it.

While the other codes mentioned may govern various aspects of building safety and standards, they do not specifically address the requirements for electrical installations in the same comprehensive manner as the National Electrical Code does. This specialized focus on electrical safety specifically marks the NEC as the appropriate standard for this scenario.
