The Registrar of Registered Electrical Contractors of the Municipal Council 1957 shows that there were more than 600 electrical contractors engaged in government and other public and private construction projects at that time. The Electrical Department of Municipal Council did not have a complete criteria on wiring and the safe usage of electrical appliances then for people of the industry to follow. That was why there were differences of opinion on electrical installation and safe usage between electrical inspectors of the Municipal Council and the contractors, resulting in frequent controversies. Leading members of the industry then thought that it was time for electrical contractors to organise themselves.
