I wouldn't agree that it's no greater. See this for example: IET Forums - Cable Trunking IP4X or IPXXD (BS 7671 Regulation 521.10.1) - https://---------------/forums/forum/messageview.cfm?catid=205&threadid=104323No greater than IPX2 or IPX4.
In fact IPXXB is 0.5mm smaller than IPX2.
I just didn’t realise the XXB/D related to internal access to live parts.
