Junction boxes are used to connect cables and wires for a active network in the field of Electrical Engineering, Control & Instrumentation and for Telecommunication applications.
MS power coated, Stainless Steel and Thermoplastics Junction Boxes are popular.
Cable/ wire size is important for selection of proper terminal blocks/connectors and the size of Junction Box varies with the cable/wire size and quantity.
In the event of thermoplastics Polyster material is good as its non flamable,
Polystyrene melts in the event of temperature rise beyond 70 degree Centigrade.
Polystyrene is good low cost material for low voltage or for telecommunication application.
ABS and PC can also me used for the area zone 2 and 22 or less.
For zone1 classifications Polyester or die cast Aluminium, steel is used.
MS enclosures are good for normal industrial and domestic applications and Stainless Steel enclosures are used for clean room area.
For telecommunication and CI applications 2.5 sq mm multiple terminal blocks are used.
