Many may see an RCBO more for the use of an electrician or professional with the idea of it being a Christmas present as a joke. Think again. Firstly for all that do not know an RCB (or residual circuit breaker) and is a device that may very well save your life. Firstly, in case you get confused, this device is known also as a GFCI in the US and is RCBO in Europe (Residual Circuit Breaker Overload).
The device can also be combined with over current protection to ensure increased safety. This can be in the same device and installed into the service panel as normal.
RCBO’s monitor the electric current between a conductor that is energized and one that is neutral. This means that when there is an imbalance of power the RCBO will disconnect the link to ensure that serious harm is not caused.
A current leakage could be the source of this imbalance and this can be done by an accidental touch of the energized part of the circuit by an unbeknown person who is grounded to the floor.
It’s important to note however that an RCBO’s does not provide protection from an overload of power or a short circuit. This is a very specific but effective tool for protecting you from a potentially lethal shock.
An RCBO can be used to protect you in various situations. Hand held power tools, kitchen utensils such as kettles, frying pans, blenders etc. and even every day products like hair dryers can all be made safer using an RCBO meaning the risk can be greatly minimised should any of these have a power imbalance.
This is a great device for safety and can be even more important when using electrical tools. If you for example are using a cutting tool and you accidentally cut through the wire you could cause serious and potentially fatal injuries to yourself. With an RCBO these potential injuries can be reduced and could very well save your life.
It is very important to note before purchasing an RCBO that you should have a good prior knowledge with electrical wiring and be used to using this kind of equipment. For anyone who does not have this prior knowledge you should hire a professional to complete the installation as there are significant risks.
It also important that you maintain and test your RCBO’s regularly to ensure that it is running smoothly. This is very simple, all you need to do is press the test button (it should be marked with a “T”). This will cause the RCBO to disconnect, as it would in a real emergency situation. This should be done every three months to ensure that your device is working properly.
Staying safe is very important to everyone in your household and an RCBO can be exactly what your home needs to maintain this. If you would like to know more about RCBO’s there are many site’s on the web where you can purchase them as well as get first hand expert advice if you have any doubts or concerns.
