Load Shedding & Your Home: Electrical Safety, Backup Power & Post-Outage Checks

Beyond the inconvenience, load shedding carries real electrical risks. Here's what to check after every outage, and how to think about backup power.

Load shedding has changed how South African homes use and protect their electrical systems. Beyond the inconvenience, repeated power cuts and restorations carry real electrical risks worth understanding.

Why load shedding is hard on your home's electrics

The surge that can occur when power is restored after an outage is one of the most common causes of appliance and geyser element damage we see. Repeated switching also puts extra wear on DB boards and breakers that weren't necessarily designed for that frequency of cycling. See our related guide on DB board tripping if this is a recurring issue for you.

What to check after every extended outage

Knowing when an outage is expected — via the official Eskom load shedding schedule for your area — helps you plan ahead, but the checks below matter regardless of whether the outage was scheduled or not.

• Listen for anything unusual from your geyser — knocking, hissing, or no hot water at all.
• Check that sensitive electronics (routers, TVs, appliances with digital displays) powered back on normally.
• Watch for a breaker that trips again shortly after being reset — that's a sign of an underlying fault, not a one-off.
• If you smell burning or see a warm plug point, treat it as urgent and switch off that circuit immediately.

Backup power options — a realistic comparison

• Surge protection — the cheapest and most overlooked layer; a decent surge protector at the DB board protects everything downstream.
• Inverter and battery systems — cover essential circuits (lights, WiFi, some plugs) through an outage without the noise or fuel needs of a generator.
• Generators — more power available, but require fuel, ventilation, and safe installation to avoid carbon monoxide risk.

Installing backup power safely

Backup power systems need to be installed correctly to avoid backfeeding power into municipal lines — a genuine safety hazard for utility workers, and something municipalities take seriously. This isn't a DIY installation for anyone without electrical training. See our house wiring and electrical installation guide for what a proper installation should include.

When a load-shedding-related fault becomes an emergency

A tripped breaker that resets normally usually isn't urgent. A burning smell, visible sparking, or a breaker that won't reset at all should be treated as an emergency call-out — see our guide on what counts as an emergency for the same logic applied to plumbing.
