How many years is the service life of a junction box
Standard materials typically have a service life of approximately five years in ordinary indoor or light industrial environments. In humid, salt spray, or high-temperature environments, the aging rate of materials may accelerate, thus affecting the long-term reliability of. Estimated useful life (EUL) represents the anticipated operational lifespan of a system or component before replacement or major repair is expected. It is also referred to as useful life (UL) or life expectancy. EUL for building systems and components reflects design and manufacturing standards. The service life and durability of a weatherproof enclosure box depends on many factors, including the environment in which it is used, the quality of materials, the quality of design, and the maintenance. Generally speaking, weather proof junction box has a longer service life and superior. On average, a home electrical panel can last between 25 to 40 years. The components, like a circuit breaker have a limited performance (10,000 mechanical operations, 10,000 load current and 50 maximum short circuit operations). After that the breaker can be replaced.

Is it okay to connect two pigtail cables without a junction box
Is it safe to splice electrical wires without a junction box? No, it is not safe to splice electrical wires without a junction box. Here are the key exceptions: Luminaires and Raceways: Splices for Chapter 3 installations (basic wiring methods) can sometimes be made within luminaires or in raceways, provided there's sufficient volume. Wire-splicing and pigtailing within a loadcenter cabinet (panel enclosure) is expressly permitted by NEC 312. 8 (A), and is quite safe (provided the splices are made up properly, of course): (A) Splices, Taps, and Feed-Through Conductors. The wiring space of enclosures for switches or overcurrent. Is it a code violation to unscrew the wire nuts and simply add an additional pigtail to the junction? If not, what is the appropriate way to do this? Thank you for your time and expertise!!! I think you would be fine. Just remember load on that circuit if you are running lots of stuff.
