A New Innovation to Wall Socket Design

Safety at home has always been the clamour of all Electrical Engineers. It is observed that wall socket failure accounts for about 25% Electrical shocks in Nigeria hence the National Electrical code has recommended the use of GFCI sockets in our today’s home.

GFCI Socket
GFCI is the acronym for Ground Fault Circuit Interrupters, it is designed to guard people against electric shock by monitoring electrical current and cutting power when the outlets detects an inbalance or excess current flow through an unintended path.  GFCI are highly sensitive and possess a fast response time than circuit breakers or fuses, it is designed to respond before electricity can affect your heart  beat i.e 1/30th of a second. The greatest advantage of this is that it can work in sockets that aren’t properly earthed, but we always advise that all outlets should be earthed properly.

Where GFCI’s Should be Used.
According to the National Code, GFCI outlets should be used in moist or wet locations of the home to protect people from being shocked. E.g Bars, Spa, Pools, Kitchen, Bathrooms, Laundry e.t.c

How to Recognise GFCI
GFCI outlets are easily recognized by the “Test” and “Reset” buttons on the socket outlet face. These buttons enables you to test regularly that your GFCI are functioning properly and to required standard. Testing your GFCI is actually fast and easy, simply press the Test button and ensure that the electrical flow has been cut off either using an electrical bulb or a small appliance, then you press the reset button to restore power.

GFCI has been in existence, but not yet widely accepted, you could contact DELWIT ( to assist with the implementation of this technology to safe guard you and the people around you.
