| 來電櫃 |
The electric switchboard to direct incoming electricity from supply source to downstream distribution panels, with necessary switching, current protection, and metering function etc. |
| 電容櫃 |
Capacitor bank is utilized for power factor correction. It can progressively compensate the inductive loading (e.g. electric motors) to make the total load appear to be almost resistive. |
| 普通MCCB電錶 |
Meters on Molded Case Circuit Breakers (MCCB) to count the accumulative electric power consumption by each MCCB for different downstream. |
