Surge Protection Is A Must
Follow Safety in Electrical Instalation Shocks
An Arcing Fault is the flow of current through the air between phase conductors or phase conductors and neutral or ground. Concentrated radiant energy is released at the point of arcing an a small amount of time resulting in Extremely High Temperature.
