Fire crews rushed to a major hospital after the smell of burning was reported to the emergency services.
Firefighters from Gorleston, Great Yarmouth and Lowestoft were sent to the James Paget University Hospital on Tuesday afternoon.
The emergency services received a call just before 3.30pm, however when they arrived they discovered the fire was extinguished before their arrival.
A spokesman said: ''A member of staff raised the alarm earlier this afternoon and, following established procedures at the hospital, the fire service were called and quickly attended the site.
'The source of the burning smell was traced to an electrical distribution board and the issue was quickly resolved.
'A small number of patients were briefly moved from the area while safety checks were carried out but all have been safely returned.
'No one was hurt and the fire service have now left the site.'
