Equipment Inside Class II Div 2

[dasarmin]

A NEMA 9 Class II Div 2 Group F & G Enclosure is to be installed.
The enclosure will be used to house a PC/TS (HMI) which will have the same rating. But what about equipment to be installed inside the enclosure; for instance a Network Switch or Black Box Port Expander or other black box devices? Will all equipment, even inside the enclosure have to have the same hazardous certification as the enclosure?

No, the enclosure is suitable to protect both the internal equipment and location. Make sure the equipment can handle the poor ventilation though.
