I am looking at installing a new camera system in a Class 1 Div 2 area.
The ethernet switches will be installed in a Type Z purged cabinet. The other end of the cable will be in an explosion proof camera enclosure.
The conduit will cross several Hazloc boundaries so we are using seal offs at both enclosures.
Is it necessary to split out the ethernet cable in the seal off or can the fact that both ends are inside enclosures be used to prevent that?
Thank you in advance for your opinions.
