the incomer MCCB rating is 100A. there is a requirement for Ammeter and voltmeter. The CT for the ammeter used has to be 20VA as per the client requirement. i have used a CT 150/1A 20VA CT. even 100/1A CT is available but it is of long delivery, bigger in dimension & expensive than 150/1A CT. CT type is RT (indoor type in Air). make is ITL (UK). my question is whether this kinda connection breaches any international standards ? Please Explain me how I can explain my client technically that it is acceptable to use 150/1A CT instead of 100/1A CT.
