CONSUMER TIPS

 

• Electrical installation in your home

The electricity supply into your home comes through the JVVNL meter. Which is sealed, and should never be touched by anyone other than JVVNL staff.
Any electrical installations from your JVVNL meter into your home (as opposed to those from the electricity network into your meter) are your responsibility. All repair work to electrical installations should be only be carried out by a registered electrical contractor.Learn how to turn off the electricity in your home in case of emergencies.

• Your Distribution Board (Miniature Circuit Breaker Board/Fuse Board)

Your distribution board is the central point of your home's electrical system. It also is the point at which your electrical wiring divides to provide individual circuits for the various applications throughout your home. e.g. Lighting, socket outlets, immersion heater etc.

• What is an MCB/ a Fuse?

MCBs (Miniature Circuit Breakers) and fuses are safety devices which cut off the flow of electricity to a circuit if a fault occurs. They can be found in your distribution board and come in a variety of strengths to protect the different circuits around your home. Always install MCBs of appropriate ratings.
An MCB can be reset when a fault occurs in a circuit, but a blown fuse must be replaced with one of similar strength. To reset an MCB simply reset the item to the 'ON' position.
The 'strength' of MCBs and fuses are measured in Amps and are found stamped or printed on them.

• Residual Current Devices (RCDs)/ELCB

RCDs guard against serious electric shock in the event of an electrical fault. They detect 'leaking' electricity from a circuit (which can occur when a cable is damaged for example) and respond by disconnecting the electricity supply from the circuit. Appliances which come into contact of water e.g. desert cooler, washing machine, mixer, etc. are more susceptible to earth leakages and therefore present greater risk of electrocution.
Most modern homes have an RCD fitted in their distribution/ fuse board, but older homes may need to install one. RCDs are also available to fit at a socket outlet as a plug- in item. Plugs which incorporate an RCD should be used for tools and outdoor equipment if there is no RCD fitted at the distribution board.

It is crucial to check whether your RCD is working correctly. To perform this check press the test button marked 'T' or 'Test' on your RCD fitted at the distribution/ fuse board, all RCDs have one.
If it is working correctly, the power to all socket circuits will immediately switch off. If the RCD fails to trip have it replaced immediately by a registered electrical contractor.
Remember reset the RCD after testing to restore power!
