just moved on to my new house 2 weeks ago, found that current is not stable. when i using the hairblower .. my 12W downlight were flickering but 18w downlight isnt.
they is a spark sound at tnb main fuse when the downlight is flickering, and i ask for electrician to check they said cause of some wiring is loose. that time is more frequent even not using other electrical. but now only when i using blower. do i need ask for tnb person to change the cut off fuse? anyone who is facing this problem?how do u fix it  cry.gif

if it's at the TNB side, just make a report and they will come to fix it foc.

at the same time, you might want to switch off the main mcb and elcb, then check and make sure all the terminals (except the live in from tnb) at the DB is tighten. sometimes the neutral terminal is loosen (most of them are hidden behind, connected to a busbar. might be a bit difficult to reach, so sometimes technician will skip it when checking
