QUOTE(13aby @ Aug 22 2024, 09:19 AM) ya will change all to hager , previously i test bought two mcb from 2 different seller . one of it when power off V test 7.xx 😢😢 suspect is fake .... the other one test V is 2.xx perfect .... Which retard teach you testing MCB in off position using voltmeter? If you learn this bullshit from local YouTuber moron then stop watching those crap misinformation. That reading will change due to the effect of capacitance/inductance. Your MCB should have sirim serial sticker or printed on it. |

QUOTE(prophecus @ Aug 22 2024, 09:27 AM) Developers have to comply to wiring regulation by Suruhanjaya Tenaga. 10 mA for water heater and wet area. 30 mA for sockets. 100mA for lighting and AC. Dei. Read back MS1979 COP on the RCDs and ER1994 regulation. Especially the highlighted word.QUOTE(prophecus @ Aug 22 2024, 09:27 AM) in the UK they have moved on to RCBO. No more RCCB as it is included in each circuit. So if there is leakage only individual circuit would trip not the whole house. In Malaysia RCBO is available for Water heater (20A, 10mA trip), the rest not widely available yet or price too expensive. Not economical to use RCBO for every circuit. Even for WH they do not carry the correct size of 20A/10mA. Most of the common RCBO is still 25A/10mA which is incorrect for the 2.5mm cut corner cables commonly installed.
