The three-phase, four-wire system does not have a ground wire. The so-called three-phase four-wire means three-phase wires and a working neutral wire. The term ground wire is not accurate. It is now called the protected neutral line, also called the PE line. Essentially, working on the neutral line is equivalent to protecting the neutral line. They are all connected to the earth. However, the grounding resistance of the two is different and, as mentioned above, the working neutral line participates in the work being done (380 to 220 V). So it works, but it can cause an electric shock.
