Unless there is no commercial power at the radar site and the radar runs on generator 24/7.
If the replacement of the generator includes replacement of the transfer switch between line and generator power then they would have to remove power from the load to replace the transfer switch. The transfer switch carries the supply current to the load whether on generator or line supply and therefore is energised when the load is energised.
