Role ground - ground Ground, also known as lightning line refers to the current into the earth wire; electrical equipment when the leakage current through the ground into the earth. Ground symbol is E (Earth); ground wire can be divided into two circuit ground. According to our current standards, GB2681 in the third circuit according to the wire color flag, the general should be yellow phase -A phase, B-phase green, C phase red. Zero line - light blue, green and yellow ground wire is, if it is a three-phase socket, the left is the zero line, intermediate (above) is the ground, the right is the line of fire. The role of ground - ground symbol in modern grounding concept, for line engineers, the meaning of the term is usually 'line voltage reference point'; For system designers, it is often the cabinet or rack; to electrical engineer, it is connected to the earth green safety ground or meaning. A more general definition of a "return to their ground is a current source of low impedance path." Here we will introduce some common ground symbol. Maintenance: Before using portable short-circuit ground wire, should confirm a priori power outage, make sure no voltage on the device after. First grounding clamp is connected to the grounding grid or flat iron, then stick with the ground operation will lead each class end line and tighten the wires on the device. When removing the short-circuit ground wire, just above the opposite order. Installation of a short-circuit ground wire from it and live equipment, taking into account the impact of the grounding wire pendulum, the safety distance should be no less than the value of the new regulations, "electrical safety work order." And use non-wrapping method is shorted to ground without clamp. If the suspension point ground, apply grounding clamp or special rod for its ground connection; if no fixed ground available; you can use a temporary grounding point, grounding buried depth should not be less than 0.6m. Portable short-circuit ground wire should be properly kept. Before each use, should carefully check whether it is intact, no to bare copper wire, nut is not loose, shall be used.
