Surge protection is one of those things that only feels essential after you’ve lost a TV or a laptop to a spike – but it’s cheap insurance against a genuinely common problem in South Africa’s grid conditions.
What causes power surges here
Load shedding switch-on and switch-off events, lightning strikes during Cape Town’s winter storms, and general grid instability all cause voltage spikes that plug-in electronics aren’t designed to absorb repeatedly.
Whole-property vs plug-in protection
A surge protection device installed at the DB board protects the property’s wiring and every connected circuit from a single point. Plug-in surge strips protect individual devices at the socket, but don’t protect the wiring itself or anything not plugged into that specific strip. The two work best combined – DB-level protection as the first line of defence, plug-in strips for particularly sensitive individual devices.
Is it worth it for homes vs businesses?
For homes with solar, inverters, or significant electronics investment, DB-level protection is a sensible one-time cost. For businesses running servers, POS systems or other critical equipment, it’s closer to essential given what a single surge event could cost in downtime or replaced equipment.
Frequently asked questions
How much does whole-property surge protection cost?
It depends on property size and the DB board’s configuration – we provide a fixed quote after a brief assessment.
Does surge protection prevent all electrical damage?
It significantly reduces surge-related damage risk but isn’t a substitute for other safety measures like earth leakage protection – the two address different risks.
