Abstract

Specifies requirements for the design, installation and operation of emergency electrical supplies for standby power and lighting in hospitals, identifies areas and functions for which emergency supplies are essential and lists the maximum delays that can be tolerated in the restoration of supplies. Appendices include examples of emergency power supply systems and associated maintenance programs. This Standard does not specify the size or type of hospitals that require emergency supplies.

Scope

This Standard sets out requirements for the design, installation and operation of emergency power supplies for power and lighting for hospitals. The Standard applies to the design, installation, operation and maintenance of those portions of the hospital electrical system in which the failure of the supply from the normal supply authority would jeopardize the effective and safe care of its patients.

Requirements for the wiring of the electrical installation for the normal supply to hospitals are specified in AS 3000 in Australia and the Electricity Regulations in New Zealand.

The Standard does not cover the special requirements for uninterruptible power supplies for computer equipment. These special power supplies should be the subject of separate specification and negotiation with the equipment supplier.

NOTE: This Standard does not apply to essential services (fire and smoke control equipment, emergency evacuation equipment and lifts) covered by AS 3000 in Australia and the Electricity Regulations in New Zealand.
