Ok, i am sure nobody asked this question before here. To cut the story short, i am about to hire a technician to change the entire MCB unit (RCD, MCB, Main Switch, MCB box). My house has the single phase electric power, but i bought the 2 pole main switch (please refer to attached photo).
Can i use it for my single phase power?
Another question is that anybody heard of 1 pole RCD or RCCB? or it's only 2 pole / 4 pole available for residential use?
The 2 pole is for neutral + live. Not for normal house DB. It is for like near to the aircon isolator box. Or near to the motor isolator box. Mostly factory use.Can i use it for my single phase power?

You can separate out by take out the joint black trigger. But some of them joint up internal or a bar across.
RCD and RCCB require 2 pole to function. Live and neutral. 4 pole is for 3phase. Both available for residential use. Depend you using single phase or 3 phase.
