Just what the title states. The house, located in India, uses old-fangled kitkat fuses. The typical domestic supply here in this part of the world is 250V AC at 50cps. I am in the middle of replacing the fuses with Miniature Circuit Breakers.
MCB appear to receive the line wire from the top connector, the bottom connector being the protected device/s. Is this universal/standard? Does the protected device connect to the top, or bottom of the MCB?
