The power tripped at night

Look out the window. If the corridor and the opposite block are dark, it is the supply. SP Group’s 24-hour Electricity Service Centre is 1800 778 8888. Use a torch, not a candle. EMA’s outage advice is to switch appliances off so they are not damaged when power returns, and to call 995 or 999 only for a life-threatening emergency.

If the neighbours have power, unplug the last appliance you used, especially a heater or an iron, and try one reset. If it trips again, or you smell burning, leave it off. The DB page prices the diagnostic and one 30mA device at S$160 to S$280. Do not bridge it to get through the night.

The full half-split method is the RCCB guide. This page is only the first ten minutes.

1. See if the outage is only your flat.
2. Torch, not candle. Switch sensitive appliances off if you can do it safely.
3. One reset after unplugging the suspect appliance. Stop if it trips again or smells hot.
4. Book the DB page in the morning rather than bridging the RCCB.

S$160 to S$280 for the published RCCB or MCB visit. SP Group 1800 778 8888 is not a charged Homey visit.

The power tripped at night stays on the circuit that is already in the board unless the load needs a new way. A like-for-like lamp, a faceplate, or a 30mA device swap is an electrician’s visit. A new circuit, a DB change, or an EV charger is EMA-licensed electrical work and is not a DIY extension lead.

Photograph the DB schedule with the cover on, the symptom (a trip, a dark room, a warm switch), and the appliance nameplate if a hob, oven or heater is involved. Do not reset a breaker that smells of burning. Prices already printed on this page are the bands to use. This note does not add a second rate.

1. Confirm which rooms die, and whether the trip happens in the rain or with one appliance.
2. Isolate before the cover comes off. The test button on a 30mA device is a homeowner check. Opening the board is the electrician.
3. Replace or repair the fitting that matches the fault. Do not bridge a protective device.
4. Label the way, test, and leave the cover on.
5. If the board is full, stop and price a DB upgrade instead of adding a spur to a crowded way.

Access to the board, the length of a new cable, and whether the building requires an LEW test change the visit. A condo may restrict drilling of the riser. An HDB flat still follows SS 638 and the EMA 30mA rule. Landed houses add distance from the intake to the point.

The same task is allowed differently in each housing type. These are permissions and access, not a new price. Board: in an HDB flat, Many HDB boards are 12-way and already full. In a condo, MCST may require the licensed electrician’s form and quiet hours. In a landed house, The intake and the sub-board can be far apart. Measure the run. Protection: in an HDB flat, EMA 30mA protection applies, including pre-1985 flats. In a condo, The same device rule. The management office may ask for notice. In a landed house, Outbuildings and wet outdoor points need the correct enclosure, not an indoor faceplate. New circuits: in an HDB flat, A new cable is electrical work, not a handyman spur. In a condo, The building may ban surface trunking in common corridors. In a landed house, A charger or a workshop circuit is designed, not tapped off a socket.
