Hair Dryer Keeps Tripping the DB Box? How to Fix Your Salon Wiring
Boss, imagine this: Saturday afternoon, full house. Your stylist turns on the hair dryer, and suddenly—PAK! The whole shop blackout. The AC dies, customers sitting in the dark with wet hair. Super paiseh, right? You rush to check the DB box while apologizing non-stop.
This is not bad luck. This is a wiring problem. After 22 years in the salon supply business, I’m telling you straight: if your wiring is cincai, your business is at risk.
Why Your Hair Dryer Always Trip the Power?
Professional dryers easily pull over 1500W to 2200W. When 3 stations turn on their dryers, plus the aircon, digital perm machine, and water heater, the current shoots up. The DB box cannot tahan, so it trips.
Also, normal house plug points are not made for salon use. You plug and unplug 50 times a day, very fast it becomes loose, overheats, and causes a short circuit.
Salon Cable Size Guide (Rule of Thumb)
| Area | Cable Size | Reason |
|---|---|---|
| Styling Station Plugs | 4mm – 6mm | Heavy hair dryer usage |
| Chemical / Perm Area | 4mm (Must) | Digital perm machine eats power |
| Aircon | 4mm (Single) / 6mm (Multiple) | Depends on horsepower |
⚠️ Note: This is an industry guideline. Always hire a wireman with a proper Suruhanjaya Tenaga license to confirm your shop’s actual TNB capacity.
Boss, Don’t Save Money Here
Electrical wiring is an “invisible” investment. Customers cannot see it, but it runs your whole shop. One blackout drives away customers; a melted wire might burn down the shop. Buy SIRIM-certified industrial plug points, separate your lighting and power socket looping, and get it done right the first time.
