I was asked to install a 100 amp run for a power supply from a 480v 250a panel, there are already three other 100 amp runs supplying the same type of power supply and a 100 amp breaker to a 120-280 transformer for a lighting panel.
They use these power supplies maybe 2 at a time but the potential to use all at the same time is there, would this install be a violation due to the potential load? There is a 600amp switch gear next to the panel should I tell them another 250a 480v panel install is required off the 600a ?? Any input is appreciated, I am somewhat new to commercial installs & calculating panel loads TIA
