Emergency Power Outage at Midnight — A 10-Step Homeowner Checklist

Introduction

Midnight. The aircond stops, the fridge hum dies, your phone battery is the only light. What do you do in the next 10 minutes? Panic wastes time; this checklist does not.

Use it in order — steps 1 - 6 are safe for any homeowner, steps 7 - 10 are when you call a 24-hour electrician.

First 60 Seconds

1. Do not touch the DB in the dark
2. Unplug expensive appliances (PC, TV, router) — voltage spike often happens on restoration
3. Turn off the iron, kettle, heater — anything left switched on

The 10-Step Checklist

Step 1: Look outside

Are your neighbours lights also off? Street lights off? Same block dark? If yes, it is probably a TNB-wide outage.

Step 2: Check MyTNB app

Open the MyTNB app — the home screen will show current outages in your area, usually updated within 15 minutes.

Step 3: Single house outage? Check the DB

If only your house is dark, walk to the DB with a torch. Look for a tripped main switch, RCCB, or MCB.

Step 4: Try to reset the main switch (once)

Flip it fully OFF then back ON. If it holds, the issue was a temporary surge. If it trips again, do not reset a second time.

Step 5: Sniff for burning

Fire can happen silently. A hint of burnt plastic in the air = do not reset anything, and call 24-hour help immediately.

Step 6: Check for tripped RCCB

The RCCB is usually bigger than MCBs, with a test button. If it is down, something downstream is leaking current.

Step 7: Unplug everything then reset

Unplug every appliance on the circuit, reset the RCCB, then plug them back one by one. The one that trips the RCCB is faulty.

Step 8: Burning smell from a wall or socket

Treat this as a fire risk. Cut the main switch, open windows, and call a 24-hour electrician now.

Step 9: Water in the DB

Rain leaking into an exterior DB is a genuine emergency. Do not touch the box. Do not use anything in the house. Call help.

Step 10: Still unresolved

If steps 1 - 9 do not restore power, the fault is upstream of safe DIY territory. A licensed 24-hour electrician can diagnose in under an hour.

When Is It a TNB Problem?

• Whole street is dark
• Street lights are off
• MyTNB app confirms it
• You hear transformer noise from the substation

In that case, wait. Electricians cannot restore TNB supply — only TNB can.

Staying Safe Until Help Arrives

• Keep the fridge and freezer closed — food lasts 4 hours easily
• Use torchlights, not candles (fire risk with children at home)
• Close rooms with aircond so the cool air lasts longer
• Keep your phone on low-power mode
