Answer / k.prakashchandra

In-built protection is for currents exceeding the rated
current of the breaker,which is usually higher than that of
your requirement.Further, you can not alter this unless you
replace the cts.

Answer / k.prakashchandra

In other words ,if the in-built CT does not meet your
requirements ,you have to use external ones.

I find that underground strip-armoiured,4core,LT PVC cables in an earthed power distribution sytem are occasionly found in charred condition-with no trace of it except ash. Is this because of no proper earth connection/continuity (giving rising to high armour resistance)in the joint enroute or because of insufficient capability (again due to high armour resistance)of cable-armour to carry fault current or due to neglected /unprotected overloading of the cable or due to high armour currents caused by power thefts where only phase(s) are unauthorisely tapped & at the point of poer consumption earth terminal is established by burring underground a not so good earthing rod (or using an underground water pipe for the purpose)
