GFCI Receptacles and Breakers

GFCI Receptacles and Breakers

The GFCI receptacle is one of the best inventions that have been made when it comes to electrical devices. The GFCI receptacle has been designed for one purpose, and that is to protect you and your family from electrical shock.

The GFCI can interrupt household circuits when there is a difference between the current in the hot and the neutral wires. When the GFCI detects the difference in current, the GFCI will automatically cut off. GFCI receptacles and GFCI breakers are very sensitive. A typical circuit breaker is designed to cut off at 15 or 20 amperes. However, someone can be electrocuted with 100 milliamps. 100 milliamps is a tiny number; it's a small fraction of 1.

We have been asked many times, “can less than one amp hurt or kill me?” The answer is yes. That is why it’s so important to have GFCI installed.

There are two types of GFCI protection.

  1. The GFCI receptacle
  2. The GFCI breaker

GFCI Receptacle Installation

Both GFCI circuit breaker and GFCI receptacle will detect a few milliamps and trip the breaker to remove a potential shock hazard. Not only can the GFCI protect you from electrical shock it can save your life.

It’s important to know where GFCI’s should be installed around your home and business. That is where John's Electric can help you today. GFCIs are required in your kitchen, bathrooms, garages and all outdoor outlets? There are certain rules that must be followed when it comes to GFCI breakers and outlets.

When it comes to GFCI’s, here is what is important.

  2. Was the GFCI installed correctly?

Amazing new technology powers wearable devices with our own sweat.

Tuesday, September 26, 2017

A team of engineers from the University of California, San Diego has developed remarkable stretchable power cells that take energy from your own sweat and power electronics, like LEDs and even Bluetooth radios!
For a field that has been struggling to come up with devices that are powerful enough and stretchable enough, these epidermal biofuel cells are a major breakthrough. The breakthrough was achieved thanks to a combination of extremely clever chemistry, highly advanced materials and electronic interfaces. This combination let them build a highly stretchable, electronic foundation using lithography and screen-printing to manufacture 3D carbon nanotube-based cathode and anode arrays.
The biofuel cells are equipped with an enzyme that oxidizes the lactic acid present in human sweat to generate current. This turns the sweat into a source of power. Because the concentration of lactic acid in a person's sweat gets diluted over time, the team is exploring a way to store the energy produced while the concentration of lactate is high enough and then release it gradually.So future work is needed before this technology can be considered a full success.
