Engineering Series - Managing power spikes / tripped fuses

Hi Residents and owners,

Another in the engineering series for residents and owners living in East Ledang.


A fact of living in Johor is power-outs and spikes in our electricity supply. I am sure all of us have experienced power outages in the last few years. Unfortunately there is little we can do for power outs. For those who travel arriving home after time away (even for a day) discovering the circuit breaker has tripped due to a power spike and finding that all that food in your fridge or freezer has gone off (not to mention if you keep fish and the pump has been off for some time).

Power spikes are common (transient voltage issues) and can be managed to some extent. The circuit breaker by design trips (switches off the power) when earth leakage or power spike is detected for safety. This is a good thing. However if we are not around to turn the power back on, the food in the fridge may waste. We can't guarantee we will always been around to switch the power on.


Lucky the fix is a relatively easy one, perhaps a little expensive (depending how much food could be wasted). Hager makes a plug in device which sits aside the main circuit breaker which in effect resets itself after a power spike. It works like this:

1. A power spike is detected - shut power off.
2. After 10 min timer (delay period) - resets the circuit breaker (turns power back on without intervention)
3. The device will try to reset 3 times in 30 mins. If it detects an actual fault (anything other than a power spike), the power will remain off for safety.
This means if the power trips due to a single spike, the power to the house will come back on without anyone needing to be there.

The Device is around the 700 MYR to purchase and needs to be installed by an electrician (it is very easy installation - 10-15 mins) Hager Auto Reset MZ912 - there are different types depending on the load required.


NOTE: If your electrical system is NOT equipped with Surge Protection Devices, protect equipment from transient as it can damage electrical items. This can be done at the distribution board or at the plug level. (another blog another time....)
