What quota should be applied to the cable trays for low-voltage electrical systems
Key Rule: The sum of cross-sectional areas of cables must not exceed 40% for power cables and 50% for control cables of the tray's usable area. Key Focus: Safe Working Load (SWL) and thermal management. Cable tray types, fill rules for single-conductor and multiconductor cables, ampacity derating, separation requirements, and when to use tray vs conduit. Tray fill limits must be calculated properly. Firestop systems are required at penetrations. It emphasizes ensuring the tray can. The primary rulebook used in the safe use of cable trays is NEC Article 392.

Where should the grounding of a residential electrical distribution box be connected
The ground goes at your main panel. In your case, the main panel is the big (but not so big, more below) panel inside. If it were actually a panel then it would likely (but not always) need to have the. Correct grounding of services depends upon understanding the definition and role of the grounded conductor. The neutral conductor is typically the grounded conductor connected to the system's neutral point, carrying current under normal operation. The primary purposes of grounding are to stabilize the system's voltage during normal operation and to provide a path for high-voltage events like lightning strikes or line surges to be. Proper grounding is the non-negotiable foundation of electrical safety.
