Why Electrical Safety Should Be a Priority
Electrical faults are one of the leading causes of house and building fires in Zimbabwe. Whether you own a home in Borrowdale or run a business in the Harare CBD, understanding basic electrical safety can protect your property, your family, your employees, and your investment.
With ZESA power surges being a common occurrence, taking proactive steps is more important than ever.
Electrical Hazards in Zimbabwean Properties
Several factors make electrical safety particularly important in Zimbabwe:
- Power surges — Voltage fluctuations from the grid can damage appliances and wiring
- Ageing infrastructure — Many homes and commercial buildings have wiring that's 20–40 years old
- Overloaded circuits — Adding more appliances over time without upgrading the electrical panel
- Illegal connections — Bypassing meters or making DIY modifications creates serious fire risks
- Water ingress — Poorly sealed outdoor connections can short-circuit during the rainy season
Essential Safety Tips for Homeowners
1. Install Surge Protectors
ZESA power surges can destroy fridges, TVs, and other expensive appliances in seconds. Invest in:
- Whole-house surge protectors — Installed at your distribution board
- Point-of-use surge strips — For individual appliances and electronics
2. Test Your Earth Leakage (RCD/ELCB) Monthly
Your earth leakage device is your last line of defence against electrocution. Press the test button on your distribution board monthly. If it doesn't trip, call an electrician immediately.
3. Never Overload Extension Cords
Plugging a heater, kettle, and microwave into the same extension lead is a recipe for disaster. High-wattage appliances should always be plugged directly into wall sockets.
4. Replace Damaged Cables Immediately
Frayed, cracked, or exposed wiring is extremely dangerous. Don't tape over damaged cables — replace them. This applies to both fixed wiring and appliance cords.
5. Keep Water Away from Electricity
Never use electrical appliances with wet hands. Ensure bathroom and kitchen outlets have proper waterproof covers. Outdoor plug points should be IP-rated for weather resistance.
Essential Safety Tips for Businesses
1. Schedule Annual Electrical Inspections
Commercial properties should have their electrical systems inspected annually by a qualified electrician. This isn't just good practice — it may be required by your insurance policy.
2. Install Commercial-Grade Surge Protection
Businesses with servers, POS systems, and industrial equipment need proper surge protection. A single power surge can destroy thousands of dollars worth of equipment and cause days of downtime.
3. Maintain Proper Emergency Lighting
All commercial buildings should have emergency lighting that activates during power cuts. This is both a safety requirement and a legal obligation for businesses with public access.
4. Ensure Compliance with Electrical Codes
Zimbabwean electrical standards require:
- Proper circuit breaker sizing for commercial loads
- Three-phase power distribution for larger operations
- Dedicated circuits for high-draw equipment
- Proper earthing of all metal structures and equipment
5. Train Staff on Electrical Safety
Every employee should know:
- Where the main switch/distribution board is located
- How to safely switch off power in an emergency
- Never to attempt electrical repairs themselves
- To report any sparking, burning smells, or flickering lights immediately
When to Call a Professional Electrician
Don't attempt DIY electrical work. Call a professional if you notice:
- Frequently tripping breakers — This indicates overloaded circuits or a fault
- Flickering or dimming lights — Could signal loose connections or overloaded wiring
- Burning smell near outlets — This is an emergency. Switch off at the DB board and call immediately
- Warm or discoloured switch plates — Indicates overheating behind the wall
- Sparking when plugging in appliances — Could be a wiring fault in the outlet
- Buzzing sounds from the distribution board — Loose connections or failing breakers
Upgrading Your Electrical System
If your property was built before 2000, your electrical system may need an upgrade. Modern electrical demands — from solar inverters to EV chargers to commercial kitchen equipment — often exceed what older wiring was designed for.
A qualified electrician can assess your system and recommend upgrades to your:
- Distribution board (from old fuse boards to modern MCB/RCD boards)
- Wiring gauge (thicker cables for higher loads)
- Earthing system (proper earth rods and bonding)
- Circuit layout (dedicated circuits for heavy appliances)
