Part 3 - Safety Guidelines for Electrical Installations in Residential Premises
3.7 - Proper Use and Maintenance of Electrical Installations
| 3.7.1 |
Arrange for immediate inspection and repair by a registered electrical contractor if the safety of an electrical installation is in doubt (e.g. current leakage or frequent tripping). |
 |
| 3.7.2 |
 |
Avoid touching any socket outlet or switch with wet hands. |
| 3.7.3 |
Each socket outlet should only be inserted with one adaptor or one extension unit to prevent circuit overload. |
| 3.7.4 |
To ensure safety, arrange a registered electrical contractor to inspect and test an electrical installation periodically even though its approved loading does not exceed 100A. |
| 3.7.5 |
When a blackout occurs, major electrical appliances should be switched off to prevent, when power supply is resumed, the occurrence of momentary circuit overload and hence a blackout again. |
