Do I have to use a grounding wire for the distribution cabinet door?

Is this wire necessary? The distribution cabinet has been reliably grounded, but the leader repeatedly instructed the distribution cabinet door to be grounded.

I have been busy at work in recent days. I started a production line in the factory before the New Year. So far, there is still a lot of work in electronic control. The leader is very anxious and urges me all day long. electrician Do it quickly, but many equipment has not been fixed yet and cannot be installed even if you want to release the cable.

So in the past few days, I can only find some work in the distribution room. If you see which wires can be connected, try to connect them as much as possible. Today, I am making a grounding wire for the distribution cabinet body. The leader came over and turned around several times. When he saw that the door had not yet made a grounding wire, he repeatedly reminded him that the distribution cabinet door should also have a grounding wire.

We replied that we were connecting the distribution cabinet with a ground wire for reliable grounding. Before the door could be done, we would connect the door ground wire after the distribution cabinet was connected.

So, do you tell me that this wire really has to be connected?

It must be grounded and must be directly on the ground and must not be connected in series.
