Applications

• To protect against the hazards of electrocution and fire risk in the explosive atmospheres associated with anaesthetics, the standard practice is to install 1 : 1 ratio isolating transformers to supply all outlets in the hospital theatres.
• WARNING: The Early Bird does not disconnect the supply. It proves an early warning of a fault, which should be remedial as soon as possible, as a second fault can cause large currents or electrocution.
