Safety is an essential attribute we secure in our home. And one major aspect of home safety revolves around electricity and our appliances. If you are familiar with fuses or circuit breakers, you might think that there is no better way of current protection. Thanks to residual-current devices or RCDs (aka residual-current circuit breakers or RCCBs), they provide a whole new innovative level of electrical protection for us.
The Ground Fault Circuit Interrupter (GFCI)
RCDs and RCCBs are other names used in the United States and Canada. In our country, these are commonly known as the GFCIs or Ground Fault Circuit Interrupters. Some people still call them ALCIs or Appliance Leakage Current Interrupters. These devices are basically electrical wiring devices that disconnect the circuits connected to them once a substantial change or leakage current is detected. What this means is that you are sure that only regulated and correct amounts of current are flowing to your connected appliances, therefore protecting them and you against even small minute amperes of current for maximum safety and protection.
How do GFCIs Work?
It is important to note the GFCI’s operation so that we may be convinced of its importance and eventually decide to purchase it. A good bird’s eye view of these devices is that they have 3 mention-worthy parts, which are the live wire, neutral wire, and a differential transformer. First off, once a circuit or appliance is connected to a GFCI’s live wire, the current flowing through the live wire will have a return flow via the neutral wire. Then, a differential transformer will come into play by detecting a current change between the live and neutral wire, if any; and even a few amperes of 5-30 milliamperes of change or leak in current will cause the GFCI to open up its connections within as quickly as 1/30 of a second with the connected appliance and the outlet to prevent possible electrical hazards. This means that we are sure that even the smallest amount of currents will safely go to Earth ground instead of landing on our appliances or worse to our own bodies.
GFCI and the National Electric Code
The National Electric Code is the electrical safety standards body of the United States, and we formerly adopted it as our own standard. But soon after, our government decided to finally have our very own Philippine Electric Code (PEC) to better suit the requirements of our country. The PEC contains vast amounts of electrical standards and safety procedures, and one of them is the inclusion of the GFCI, that each Filipino household should install this electrical technology for safety.
The primary reason for having a GFCI is to ensure that a ground fault will NOT be absorbed by a human being. This is because even 5ma can lead to shock and injuries as per the Occupational Safety and Health Administration or OSHA. GFCIs can dissipate even 5ma as we have mentioned so anything above that threshold will also be eliminated. Not to mention that all our appliances too will be surge protected, thus eliminating chances of fires caused by current leaks. Even small leakage currents can lead to death so no wonder the PEC required us to have GFCIs.
If you are looking for maximum electrical safety via using GFCIs, then look no further as Meiji has 2 GFCI models to choose from! The GF-250 (220V) and the LG-20 (110V), both of which are UL and CSA certified for that safety and quality assurance.
Both models are very convenient to use as they can be installed as ordinary wall outlets, so that you can EASILY plug-in your appliances without hassle. They are in duplex form with a load capacity of 20 amperes which are enough to plug in 2 apparatuses at the same time. They are also made of high quality polycarbonate glossy white materials that are cost efficienct and bring aesthetics to your home!
So if you are looking to protect you and your family, look no further and get Meiji GFCIs, install them around the house and for sure you can have that peace of mind that no electrical hazards will threaten you and your home!
