220V DC Hazard in Busbar System – Wiener
The grounding of the DC system should include two conditions: the one-point grounding of the DC system and the two-point grounding of the DC system.
In the DC system, the positive and negative poles of DC are insulated from the ground, and they do not cause any harm when generating a ground current because there is no path to constitute a grounding current, but the ground of one pole is long.

The role of plug-in busway – Wiener
Generally speaking, plug-in busway is mainly used for power transmission. We know that all conductors will have losses, and the losses caused by the flow of electricity through conductors are larger and some are smaller. For example, compared with the aluminum wire with the same wire diameter and the copper wire, the loss of aluminum is larger, and the loss of copper is smaller. That is, the conductivity ...
