Apakah perbezaan paling ketara antara RCCB Type A dan RCCB type AC selain dari perbezaan kos..
Dimanakah peralatan RCCB type A boleh digunapakai dengan mengambil kira kos dan operasi yang optimum.

Best answer
Type AC RCCB is designed to trip with sinusoidal residual currents which occur suddenly or slowly rise in magnitude. Type AC RCCB is only designed for use with linear loads that produce sinusoidal residual currents at 50Hz.

Type A: Certain devices during faults can be the source of non-sinusoidal earth leakage currents (DC components) due to the electronic components e.g.: diodes, thyristors. The type A RCCB is designed to ensure that under this conditions the RCCB operates on sinusoidal residual current and also with pulsating direct current which occur suddenly or slowly rise in magnitude.

Kebanyakan lampu sekarang menggunakan LED. Adakah Type A RCCB lebih sesuai digunakan? dan jika type AC RCCB digunakan adakah menjadi kesalahan?

Type A lebih sesuai digunakan kerana lampu LED adalah non-linear load. Tidak menjadi kesalahan kerana tiada ketetapan lagi oleh Suruhanjaya Tenaga.
