Three separate feeds serving a local university’s library building had reached the end of useful life and needed to be replaced.
Roberts Onsite’s electrical team removed the three feeds powering the seven-storey building and replaced them with one.
We removed the existing distribution which included the motor control centre (MCC), panels, splitters, disconnects, and a 45kVA transformer. We then supplied and installed a 600V distribution panel, a 225kVA 600/120V transformer, and a 120/208V distribution panel.
We supplied and installed an 800A breaker in the main electrical room in a nearby building on campus, which powered the new 600A distribution installed in the library building. Our team installed about 450’ of 3” conduits to house the feeds running between the two buildings.
The oversized MCC and distribution powering the various mechanical pumps, air handling units and branch panels within the library building was removed and replaced with one better suited to the space constraints within the electrical room. The existing loads were connected to the new MCC and distribution panels as required.
