If your power keeps cutting and you are forever walking to the DB board to flip a switch back on, you are not alone. It is one of the most common calls we get from homeowners across Cape Town. The good news is that a tripping breaker is doing its job, it is protecting you. The question is what is making it trip.
What a tripping breaker is telling you
A breaker trips when it detects more current than it is rated for, or when it senses a leak to earth. Both are safety responses. Resetting it over and over without finding the cause is like silencing a smoke alarm without checking for fire.
The common causes
1. An overloaded circuit
Too many appliances on one circuit draw more current than the wiring is rated for. This is especially common in older Cape Town homes wired for a lighter era, long before every room had multiple devices, a kettle and a heater.
2. A faulty appliance
Sometimes it is not the wiring at all, it is a single appliance with a fault leaking to earth. A quick test: unplug everything on the affected circuit, reset the breaker, then plug items back one at a time until it trips. The last one is your culprit.
3. Earth leakage
The earth leakage unit trips when current is escaping where it should not, often due to moisture or damaged wiring. In Cape Town's wet winter months, water ingress is a frequent trigger.
4. A worn or faulty breaker
Breakers wear out. An aged breaker can trip for no clear reason, or worse, fail to trip when it should. That second case is the dangerous one and needs professional attention.
Safety first: if you smell burning, see scorch marks, or the board is warm to the touch, do not keep resetting it. Switch off at the main and call an electrician.
What you can safely check yourself
- Unplug appliances on the affected circuit and reset once
- Note whether it trips instantly or after a while
- Check if it is one circuit or the whole board
- Look for any recently added high-draw appliance
When to call an electrician
If the board trips the moment you reset it, if it is the earth leakage that keeps going, or if you cannot isolate the cause, it is time for a professional. We trace the actual fault rather than guessing, and fix it once. For a persistent tripping problem in Cape Town, get in touch and we will diagnose it properly.
