MCB / RCCB FAQ
What MCB rating do I need for my home?
Standard 2BHK home uses 6A MCB for lighting circuits, 16A for sockets, 25A for AC / geyser, and a 40–63A main incomer. Total DB board is typically 6–8 way.
RCCB vs ELCB — which is better?
RCCB is the modern replacement. Detects earth-leakage as low as 30mA, better sensitivity, meets current IS standards. All new builds should use RCCB.
Do you stock MCCB for factory loads?
Yes. Altech MCCB 40A to 630A, and Anchor by Panasonic MCCB for motor / distribution applications. 1–2 day lead time for higher ratings.
Is the MCB rating printed on the DB board important?
It is the maximum busbar capacity. Do not exceed it. Common ratings: 63A for SPN 6-way, 100A for TPN 8-way.
