Note: This may ruin the silicone seal some developers put on the switches n sockets - but without actual On a sidenote, generally the better brands for DB box components will be (top tier) ABB/Hager/Schneider, (midrange) local brands, (recommend to change) elcheapo China brands .. whilst all are also SIRIM certified.. but there are quality differences. Personally I use top tier stuff like ABB for my own home although I don't make much money to afford a nice landed, but peace of mind when sleeping is important.

My rumaweep came with some elcheapo China brand, I deleted whole DB box and installed a proper one with top tier components.
