Dear Sir / Madam,
Actually we requied 64 A MCB,
But i have 32 A MCB = 2 No's
this two i have to make series connection and we usw any
place?
isit possible or not......
Answer Posted / 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
