Phase segregated terminal boxes to eliminate phase to phase faults. In the event of a fault developing between phase and earth in one of the glass reinforced plastic terminal enclosure, the rapid buildup of pressure will cause the enclosure to fracture across the rear wall, thus releasing hot gases and flame into the steel phase segregated compartment.
If the fault level is low, fault products will be contained within the compartment.
If the fault level is high & excessive, then the Bakelite relief disc will fail and the fault product will pass into the motor interior where it will rapidly cool and disperse by venting into the machine space phase to phase fault are thus eliminated.

Fault Characteristics 
The amount of energy released during a fault in a terminal boa is a direct function of the fault current, the arc voltage, the number phases. involved, and the time duration. 

The fault current is determined by the design of the terminal box. Unit transformers, reactor, and neutral earthing impedances are sometimes used to limit the fault level at any particular point of the system, but they have to be designed as part of the system if stable operation is to be obtained.


The duration of a fault depends upon the type of switching and protective gear used HV • HFC terminal boxes are designed and tested to withstand a full-rated. 


Fault for 250 milli seconds and on therefore be used with normal circuit breakers and relays. Conductor sizes and joints are suitably proportioned and secured to carry fault current resulting from failure inside the mushier without damage or danger.


Construction:
The phase segregated terminal box comprises a " fabricated steel casing welded to a heavy gauge back and t plate. The outer steel case encloses an inner fabricated steel shell and steel barriers extending from top to bottom of the inner shell. The terminal box thus has three distinct segregated phase compartments, each completely shrouded by steel walls which are solidly connected to earth. The presence of the inner skin prevents an internal arc from 'flame-cutting' a hole in the outer casing and thus allowing hot gases to discharge into the atmosphere with consequent danger to personnel. As an additional safeguard the terminal is enclosed within a glass reinforced plastic moulded type enclosure. Cables from the motor interior and the intermediate the enclosure- Neoprene/cork gasket. prevent the ingress of dirt or moisture. Each compartment is fitted with a desiccator unit which provides a visual indication of moisture within the box in any phase. The desiccator unit can be removed while the motor is running.
