Additional Information

The Use of Multiple Adaptors in a Single Entry for Ex Equipment

The IEC 60079-1 standard allows the use of threaded adaptors and reducers for direct entry into Flameproof type ‘d’ enclosures. In future, the female connection threads of the adaptors and/or reducers will be limited to metric or NPT only. When using thread adaptors and reducers or reducer bushings, only one is permitted for any single cable entry of Flameproof type ‘d’ (Ex d) equipment.
