Few yrs back I was asked to give a training to company providing Ex installations. Since that time we do yearly follow up mainly focusing on one topic: Ex glanding.

Why is it that problematic?

- all are Ex, but not the same

- many do JB in Ex d, but consider it Ex e

- it is only a gland

- ...

There are many possible replies...

What is important here? Choose the gland based on protection method of housing. That is the most simple way of going ahead. But if you choose one level higher - see pic - than consider min. requirements of the selected Ex gland.
