50*4 hot dip galvanized flat steel can be used as grounding. How many square feet can be used instead of ground wire?
GB is not 50*4, but 4*40; International Electrotechnical union IEC is 3*25 can also, and if it is small houses, GB only 6mm diameter of it. It can be seen that the size of flat steel is mainly due to the consideration of mechanical strength and more than the consideration of electrical performance
In general, our project has no discretion to select the ground wire specification of 16mm. Europe is 25mm2
The national standard is considered from an electrical angle. The size of the ground wire is defined as the same diameter of the ground wire and the phase line;
You say flat steel grounding, and later said mountain laying, should be interpreted as the lead of the earth pole, grounding project called "zone"
