Ops. OK let me clarify.
MDSC0039 2000w = Burn
PC PSU = Burn
PC = OFF
PC power socket = ON
Hope you understand. So my question is, should i use the MDSC0039 1000w instead in the future to avoid the same thing happening?
FYI, mobo is the one to control the PC operation (on/off) but PSU are the one keep supplying the power source to mobo...
if PSU detected signal from mobo, the PSU will supply power to all the hardware thru all the connectors...
what i means here it could be equipment wear and tear as the TNB still feeding the PSU and it still operating on hot standby mode...
same case like TV switched off but TNB still feeding power into its power supply unit for hot standby purpose, even though pour water on TVs PSU and it will short circuit as well even though under standby mode...
so if the equipments short circuited due to wear and tear (out of cal lab's control), it will effected cal-lab operation too...
believe u have the experienced that bad / damaged equipments will tripped the ELCB...
anyway, it still difficult to justify whether cal-lab failed as we have to concerned on equipment wear and tear, improper equipments usage & handling, unstability electric source, used cheap electric components, etc... that the reasons doesn't cover for such incidents increased the probability of damages of equipments which wasn't caused by lightning...
