Three-wire socket with three-wire plug how ah?
Zero, just fire and zero can be separated, because the electrical plug on the two holes, you do not have a fixed interpolation, not casually inserted, as long as the socket fire and zero can be separated
FireWire and the zero line can only be separated from the next, not allowed to zero right fire
Yellow is the line of fire is blue line is mixed with the ground line, the general use of electricity without electricity, especially in rural areas
As long as the ground connection, the remaining two one for the FireWire another line for the zero line, how can access
