The element <groundingType> is used for electrical functional items (grounding points). It indicates the grounding type or bonding segregation, which is necessary to perform the appropriate ground tests after installation. The grounding type is specified according to the current type, the voltage and the system essentiality (eg, current return for 230V DC power supply in non-essential system 2). The bonding segregation is specified according to signal type and system essentiality (eg, bonding point for wire linked to essential system 1).
