PORTABLE GFI SAFETY ELECTRICAL INFORMATION 120V GROUND FAULT INFO: GFI LINE TO LOAD DIAGRAM

PORTABLE GFI SAFETY ELECTRICAL INFORMATION 120V GROUND FAULT INFO

PORTABLE GFI SAFETY ELECTRICAL INFORMATION 120V GROUND FAULT INFO:  This is the information every person working in the industrial industry that has to work with portable lighting products or portable power cords or even portable temporary electrical power distribution products should be make to read and understand.  This information will prevent workers from being injured due to ignorance of electrical safety pre-cautions.  Over a 1000 people a year die of electrical shock.  30 time more people are injured through electrical shock.  Portable, electrically, operated tools account for the second largest number of injuries. The plug or cord at fault in two thirds of the accident.  It is said, it is not the electrical shock that kills most workers, it is the fall, afterwards.  Please read over the safety information provided within this notice.

Description

PORTABLE GFI SAFETY ELECTRICAL INFORMATION 120V GROUND FAULT INFO:  Portable Lighting, Portable GFI Product, Portable Extension Cords and Portable Power Cords along with Portable Job-site Electrical Distribution products.

The following is a list of Electrical Terms and their defined explanations of how they negatively affect, working personnel.

#1:   LEAKAGE CURRENT… One of the most important checks to be sure a tool is safe, is for excessive leakage current.  Leakage current flows from the internal wiring to metal portions of the equipment housing or enclosure of being handled.  The skin offers a barrier to the flow of leakage current.  It is not until voltage exceeds about 48 volts that a hazard exists.  At a common supply voltage of 120 volts, current can easily pass through the skin.  Once the current starts to flow, the skin’s resistance decreases further, allowing an increasing flow of current to pass through the body. Boss hopes this information on PORTABLE GFI SAFETY ELECTRICAL INFORMATION 120V GROUND FAULT INFO is found to be helpful.

#2:   PERCEPTION CURRENT… One milli-amperes ( 1/1000of an ampere- .001 amps ) will be felt by most individuals as a light tingling sensation.  A defective hand drill or floor polisher might allow this amount of current to flow through a person standing on a dry wooden floor.  Not bothered by it, he continues to sue the equipment until he happened to touch a water connection, heating register, metal window sash, or other grounded metal object.  He has now completed the circuit to ground and much larger current will flow through his body.  This can happen when handling, portable explosion proof hand lamps, portable 150w watt LED floodlights that are mounted on potentially partially grounded metal stands that do not have electrically conductive rubber wheels. The information supplied by Boss pertaining to PORTABLE GFI SAFETY ELECTRICAL INFORMATION 120V GROUND FAULT INFO may save a life.

#3:    SHOCK LEVEL… If only five milli-amperes (1/43 of the current required to operate a 25 watt lamp- .005 amp) flows through your body, it will result in a violent muscle reaction throwing you away from the electric tool or equipment being handles.  Portable Job-site electrical distribution products not properly grounded, picking up a portable water proof hand lamp by the metal guard, touching any in-ground metal frame associated with an electrical power device will cause this reaction to working individuals.  This information within PORTABLE GFI SAFETY ELECTRICAL INFORMATION 120V GROUND FAULT INFO is valuable to the rookie and well as the journey-man if nothing more than a simple reminder.

#4:    LET-GO CURRENT…  If the current is much above 10 milli-amperes, the person will lose his ability to release his grip on the electrical power tool-equipment.  While the heart normally can continue to function, fatique sets in, followed by death if no help is available.

#5:    ELECTROCUTION…  At about 100 milli-amperes (less than half that used to by a 25 watt lamp) ventricular fibrillation occurs, the muscle fibers lose control and the heart is not longer able to pump blood.

#6:    SAFETY…  The levels of current for perception, let-go and ventricular fibrillation vary widely from person to person.  The above figures are based on the standard reactions of normal, healthy individuals.  The effect of electrical shock on a child, elderly or sick person is much more severe.  Even very small amounts of electrical current can startle a person, causing him/her to fall from scaffolding, ladders or jump back into a greater hazard.  For this reason, most manufacturers of electrical tools, appliances and motors follow Underwriter’s Laboratories recommended maximum leakage current of 0.5 milli-amperes. The purpose of Boss presenting this PORTABLE GFI SAFETY ELECTRICAL INFORMATION 120V GROUND FAULT INFO is to possibly save a life.

NOTE:  Any tool which is found to have leakage current in excess of 0.5 milli-amperes should be immediately identified with a red tag as unsafe, and repaired by a qualified personnel in accordance with manufacture’s recommendations prior to returning to service.
