In modern society such as Singapore densely populated by high rise building, we are vulnerable to electrical failure within our home even though the government have given us good stable power supply throughout the year. Most common power failure we are going to discuss is to teach consumer on how to temporary restore power in 15 minutes before engaging a qualified elctrician to inspect and resolve any problems. With the invention of the ELCB or RCCB which has given good safety to consumers but have also created a problem of inevitable power tripping. The function and how it works can be easily googled and here we are only to teach the 15 minutes power restoration procedure only for HDB flat residents: *** Please take note for precaution that your hands are dry and you wear a dry rubber slipper while attempting to DIY restore power and that no doubts the STEPS are perfectly SAFE PROCUDURES according to PUB regulation, I am not responsible for any unfortunate incidents that may result from this DIY advise and all actions are purely by your personal decision, responsibilties and liabilities.*** 1. Always have a good working torch light ready in the house place at the Electrical DB panel incase the blackout is at night. 2. When power trip, do not panic and if during the day it would be easier and if at night just use the torch light. 3. Go to DB panel open the DB Cover and shine see the Breaker switches must all be UP and if any 1 or 2 switches is down do not push up immediately. 4. Take a breath and recall or ask anyone in the family what was the last action that cause the trip, or is it just trip by itself. 5. If anyone can recall the action, then just use the torch light if at night and go see what was it and have it turn off and if there is a plug top just unplug it. 6. Then go back to DB to push back up the 1 breaker switch especially the 1 with the reset button follow by the other individual breakers within a row. 7. However if there are NO BREAKER Switches down then just push down every Breaker switches and similary repeat Step 4 and 5 8. Once all the Breaker switches are down and step 5 taken then go outside look for the Electrical Meter and find the external incoming supply breaker. 9. If anyone breaker is down and you have switch off all breaker in your house by pushing down, it will be very safe to just Push Up the Tripped Breaker. 10. Once restored power outside, go back inside DB to 1st push up the Main MCB which is 40A or 63A follow by the RCCB which have the reset button. 11. Finally start pushing 1 by 1 starting from the breaker label showing 6A or 10A which is for the lights. 12. If at any moment you push up and cause the RCCB to trip again, do not panic just leave the Breaker DOWN and reset the RCCB again. 13. Continue until all breakers are up position except for those that trip and call us or your regular electricain to attend to the Breaker that is down. 14. You may DIY to go find which part of the house do not have power and see if you could find anything that cause the trip, just unplug or switch off. 15. The above are for Power Trip by RCCB only, due to either carelessness on multi adapter, hair dryer, ironer, kettle, oven, dryer or the lightinings, etc.
