Color of grounding strip in distribution box
The mandatory colors for power wiring in the National Electrical Code (NEC) are Green, Bare, or Green/Yellow (a yellow stripe or band on green) for the protective ground (PG), and White (or alternatively Gray) for the neutral wire. They make it easy to identify immediately which wires are live, neutral, or grounded (avoiding costly mistakes and hazardous accidents). Color codes are used in electrical wiring and resistors in electronics, safety signals road. These color codes are used for electrical distribution systems, and while some are mandatory, others are optional. National Electrical Code (NEC) Section 250. The basic rules are: Wire-type equipment. The IEC 60446 standard, “Basic and Safety Principles for Man-Machine Interface, Marking, and Identification,” establishes global guidelines for identifying electrical equipment terminals, conductors, and wiring colors. Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used.

Standard for Distribution Box Rails
DIN rail is a standardized metal rail used for mounting industrial control equipment inside equipment racks and enclosures. Defined by standards such as IEC 60715 and EN 50022, the most common type is the 35mm “Top Hat” rail (TS35). DIN rails are designed for securely attaching electrical and industrial control products - such as circuit breakers, terminal blocks, power supplies. Global Standard: DIN rail is the universal industry standard (IEC 60715) for mounting electrical components in control panels, ensuring cross-brand compatibility. Aluminum and stainless steel rails are also available. It is usually made from steel or aluminum and, thus, has the specified measurement set by the Deutchs Institut fur Normung (DIN), enabling it to be compatible. Steel DIN Rails are indispensable installation components in electrical equipment due to their standardized design.
