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

If the spark is at TNB main fuse you may call TNB helpline to have them sending their guys over to check... Good to take some videos which can show the issue clearly

If it is after the TNB meter then you would need to engage an electrician contractor to come over for troubleshooting,


Until issue is rectified, please be extra careful with your electric usage. If can you might want to access your distribution box and press the "Test" button at the RCCB to ensure it is working

Call Tenaga on 15454 and make a complaint. They will attend quite promptly to it as the incoming fuse belongs to them.

Always remember to take video if u measure the voltage reading, got evidence easy to complain.

i) single phase supply with nominal voltage of 230V, range +10%, -6%; (216.2v - 253v)
ii. Three phase supply with nominal voltage of 400V, range +10%, -6%; (376 - 440v)
iii. Permitted frequency is 50Hz + 1%;

thanks for all of the advice, but i realise only my downlight will flickering..eyeball/ hanging light wont flickering.. is it my downlight problem?

Wiring loose.. those light/dimmer wire they give ciplak cable not much thicker than hair one
so it is not uncommon for them to break loose

If I were you I'd buy a dozen of the clamp-type wago connector like these https://my.element14.com/wago/221-412-ve00-...2pos/dp/2536249
make life easy no need to struggle due to the thin wires falling out from screw terminal block

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
