If you have lost a TV, decoder or inverter to a summer storm or a load-shedding spike, you already know the Highveld is hard on electronics. Here is how proper surge protection actually shields your home.
Two threats, one solution
Johannesburg sits in one of the most lightning-dense regions on earth, and load-shedding adds a second hazard: a voltage spike the moment grid power returns. Both send a surge through your wiring that can fry anything plugged in — TVs, computers, inverters, fridges, gate motors and pool controllers.
How whole-home surge protection works
A surge arrestor is fitted at your distribution board and diverts excess voltage safely to earth before it reaches your circuits. It is the first and most important layer, protecting everything downstream from a single spike.
Layer it for sensitive electronics
Add plug-level surge protectors for the expensive, sensitive items — entertainment units, computers, the inverter. The DB-board arrestor handles the big hit; the plug protectors mop up what gets through.
The load-shedding connection
That switch-on spike when power returns is one of the most common causes of appliance failure during load-shedding — which is exactly why surge protection is no longer optional on the Highveld. See our surge protection service.
Cheap insurance
A whole-home arrestor is a modest one-off cost — far less than replacing a TV, fridge and inverter after one strike. Get your home protected before the next storm season.
