How to do a basic Emergency Electrician safety check and quick fixes

Quick answer (read this first)

• First, determine if the power issue is widespread (whole house) or localized to a single room or appliance.
• ALWAYS switch off the main power supply (from your DB box) before touching any electrical components.
• Locate and safely check your circuit breakers or fuse box for tripped breakers or blown fuses.
• Only attempt simple fixes like resetting breakers; never touch exposed wires or undertake complex repairs.

Safety first

• Always turn off the main power supply (from your main circuit breaker or WAPDA/KESC main) before inspecting anything.
• Use insulated tools (screwdriver, pliers) and wear rubber-soled shoes for personal insulation.
• Never touch exposed wires, wet surfaces, or areas with burning smells or smoke.
• Do not overload electrical sockets or use damaged extension cords.
• Keep children and pets away from the work area.

Tools you may need

• Voltage tester (test pen)
• Flashlight or headlamp
• Insulated screwdriver set
• Rubber-soled shoes
• Spare fuses (if your home uses a fuse box and you know the correct rating)

Step-by-step

Step 1

1. Identify the Problem Area: Determine if the power outage affects a single appliance, one room, or your entire home. This helps narrow down the potential cause.

Step 2

2. Safety First: Disconnect Power: BEFORE touching anything, locate your main distribution board (DB box) and switch OFF the main circuit breaker. Confirm power is off using your test pen if unsure.

Step 3

3. Check Main Breaker/Fuse: Inspect the main circuit breaker in your DB box. If it’s in the ‘OFF’ or central position, it has likely tripped. For older homes with fuse boxes, visually check the main fuse.

Step 4

4. Inspect Branch Circuit Breakers/Fuses: Carefully examine individual circuit breakers. If any are tripped, switch them fully ‘OFF’ then back ‘ON’. For fuse boxes, check for blown fuses (darkened glass or broken filament) in the affected area’s circuit. Replace only if you have the correct rating spare and are confident.

Step 5

5. Examine Plugs and Cords: With the power still off (or off to the affected circuit), unplug appliances from the affected area. Look for any loose connections, burn marks, frayed wires, or damaged plugs on appliances and extension cords. Replace or repair damaged cords/plugs if it’s a simple, safe fix, or discard.

Step 6

6. Visual Inspection of Outlets/Switches: From a safe distance, visually check wall outlets and light switches in the problematic area for signs of burning, melting, sparks, or unusual odors. DO NOT touch any damaged components.

Step 7

7. Restore Power and Test: Once checks are complete and minor issues (like a tripped breaker or loose plug) are addressed, switch the main power back ON. Carefully test the affected outlets or lights. If the issue persists or a breaker trips immediately, turn power off again.

Common mistakes

• Forgetting to turn off the main power supply before touching electrical components.
• Using incorrect fuse ratings or bypassing circuit breakers.
• Overloading electrical sockets with too many devices.
• Attempting complex wiring or repairs without proper knowledge or tools.
• Ignoring burning smells, sparks, or buzzing sounds from electrical fittings.

When to call a professional

• Circuit breakers trip repeatedly after resetting.
• You smell burning or see smoke from outlets, switches, or the DB box.
• There are sparks, buzzing, or crackling sounds from electrical fittings.
• You have no power to the entire house or multiple areas, and the main breaker isn’t tripped.
• There are exposed, frayed, or damaged wires anywhere in your home.
• You are unsure about the cause of an electrical issue or feel uncomfortable performing the checks.
