Why Cape Town Electronics Die During Stage 6
When Eskom cuts and restores power, voltage can spike above 1 000 V for a split-second—plenty to fry TV power boards, fridge compressors, and inverter controllers. Insurers confirm that “surge & lightning” claims have now overtaken burglary claims for Western-Cape households.

Quick Tests You Can Run Tonight
Multiplug Check – if it cost <R100, it’s just a fancy extension cord; replace with a surge-rated model.
DB Board Scan – open the cover: no “SURGE” breaker? Time to add one.
Inverter Isolation – does your inverter feed and grid feed run through a legal double-throw switch? If not, you risk back-feeding Eskom—and voiding warranties.
Warning Signs: Call an Electrician ASAP
Lights brighten then dim when power returns.
You hear a “click-buzz” in the DB board during reconnection.
Metal-clad appliances give a slight shock when touched.
