It usually happens suddenly.
You turn on your washing machine or start cooking with your induction cooktop, then everything goes dark. Your main switch trips again.
If you’re living in an HDB flat, condo, or landed home in Singapore, this is a very common issue, especially during humid weather or in older electrical systems.
But here’s the truth: most homeowners don’t know:
RCCB tripping is NOT about overload, it’s about electrical leakage.
And ignoring it can be dangerous. MM Engineering offers emergency electrical services in Singapore.

Its job:
This is the #1 cause we see.
Moisture & Water Seepage (Very Common in SG)
Singapore’s humidity + rain = hidden danger.
High-risk areas:

Small leakages add up → RCCB trips
Very common in:
Needs testing or replacement
If it trips → you found the faulty device
Still trips = appliance problem
No trip = wiring/socket issue
Look for:
