  2. be capable of started automatically on the failure of the main source of electrical power supply unless a transitional source of emergency electrical power is provided in accordance.

If the emergency generator is arranged for automatic starting the generator and the services that would otherwise be supplied from the transitional source of emergency electrical power in compliance with the requirements , shall be automatically connected to the emergency switchboard so that such services will be supplied within 45 seconds of the failure of the main source of electrical power.
