Hi, sorry this is not home use but industrial, but don't know where to ask. hope I can find some answer here. if I have a equipment that need to hook up to a supply, should I use a 20A isolator or 32A isolator? my equipment is a 230V single phase. when do I use a 20A when to use a 32A? thank you

Hi Yoong, so is it alright if i plug in my 20A appliance into this 13A wall socket? will it cause anything? Thank you

Hi yoongf, should be 32A SP MCB? or 20A MCB? from the pic, it should be 32A MCB for P4 to P6? am i right? since it is a 32A MCB, then why there is a 13A S/S/O in ring circuit at the PP1 to PP 10? what does it mean? Thank you

Hi all. if my HDB home is fitted with a 40 amps main switch, and i plug in a 20A electrical appliance into a wall socket, will it cause any failure or trip? so if i plug into P4 is it ok, since P4, P5 & P6 is 32A MCB, it should not trip right? Thank you
