Resetting a tripping breaker over and over without finding the cause
A breaker that keeps dropping is doing its job; the fault is still there. Repeated forced resets stress the breaker and, in worn boards, can overheat the buswork behind it. Reset once after unplugging the circuit's appliances; if it will not hold, stop and book a diagnosis.
Fixing nuisance trips by fitting a bigger breaker or a less sensitive RCD
Upsizing protection to stop tripping removes the safeguard while leaving the fault. An oversized MCB lets cables run hotter than they are rated for inside walls, and a desensitised RCD stops protecting people from a leaking water heater. Any vendor proposing this as the fix is the wrong vendor.
Treating outdoor electrics like indoor electrics
Indoor-grade junction boxes in flowerbeds, unrated extension cords feeding garden lights and balcony sockets without covers all fail the same way: moisture gets in, the RCD starts tripping, and the search for the wet joint costs more than proper IP-rated fittings would have. Outdoors, specification is the economy.
