Storms, tree strikes, and grid events can send short power spikes into your home. These spikes can damage fridges, TVs, and lights. A basic powerboard is not enough for every spike.
The three layers
Type 1: Fitted at the main switchboard. Handles large surges from outside the home.
Type 2: Also at the switchboard. Catches most day to day spikes.
Type 3: Plug-in protection or device level. Protects sensitive gear like TVs and PCs.
These three layers work best when used together.
Why LEDs still blow
LEDs have small drivers inside. Small, repeated spikes wear them out. A single cheap powerboard may not catch every spike. Good earthing and the right breakers help reduce stress on drivers.
