5. Arahan Operasi
The ABB PowerMark Plus panel serves as the central distribution point for your home's electrical circuits. Individual circuit breakers within the panel protect specific circuits from overcurrents and short circuits.
5.1 Understanding Circuit Breakers
Each circuit breaker controls a specific circuit in your home. When an overload or short circuit occurs, the breaker will "trip" (move to the OFF or middle position) to interrupt the flow of electricity and prevent damage or fire.
5.2 Menetapkan Semula Pemutus Litar Tersandung
- Identify the Tripped Breaker: Locate the breaker that is in the OFF or middle position.
- MATI: Firmly push the breaker handle completely to the OFF position.
- HIDUPKAN: Firmly push the breaker handle completely to the ON position.
- If the breaker immediately trips again, there may be an electrical fault or overload on the circuit. Do not attempt to reset it repeatedly. Consult a qualified electrician.
It is advisable to label each circuit breaker clearly to identify which areas or appliances they control.
