The company is powered by a dual-circuit 20KV supply system; is it one in use and one as a backup, or can both be used? My understanding is that it’s one in use and one as a backup, as the power supply company probably does not allow both to be used simultaneously, with the backup power source serving only as a supply source for secondary loads.
Yes, so I was wondering if there are any options where everything is enabled; it actually comes down to the issue of charging based on the designed capacity.

It was approved by the power supply authority; they have been operating side by side for seven or eight years now
1. They can operate in parallel, with each circuit carrying part of the load, and a bus coupler is added in between. 2. It is sufficient to ensure that there are two closed circuits between the two incoming circuit breakers and the busbar circuit breaker; this improves the reliability of power supply. 3. There are facilities for shutting off non-firefighting power sources, so when the busbar is closed, only the first and second level loads from another circuit are powered, not all the loads. 4. This involves costs related to high-reliability power supply, and these costs vary from place to place
