Answer / sagar

NO.
Because
MCB is used for over current protection.
you require 64A MCB for protection.
now if you will use 2 MCB of 32 A , then both the MCB will give protection for 32 A and will trip at 32 A.
so , you can't use the 32 A MCB in place of 64A MCB

Answer / hemant

if u connect 2 mcb's in series then it share load up to 32
amp only not for 64amp. if u used this two mcb then u must
to divided load in to two section like 32/32 amp. after
then u can connect load to out going terminals of mcbs.

Answer / nur.asidik
