Isolation of uninterruptible power supply systems or standby generators

Control Measure Knowledge

If an uninterruptible power supply system is providing back-up to a whole building, there should be a cut-off point, usually located near to the isolation point for the mains power.

If a standby generator is providing back-up to the facility, it will need to be isolated to prevent the automatic re-energising of power supplies.
