"List of old electricity rules that are no longer used"
This schedule lists many regulations and orders that are no longer in effect. These rules were about different aspects of electricity, like how to work with power lines, how to register as an electrician, and how to safely wire buildings.
The list includes changes made to these regulations over the years. For example, there are several amendments to the Electric Linemen Regulations 1960 and the Electrical Wiring Regulations 1976. These amendments show that the rules were updated multiple times to keep up with changes in technology and safety standards.
By revoking these regulations, the government is saying that they are no longer valid or in use. This usually happens when new, updated rules replace the old ones to better protect people's safety and reflect current practices in the electricity industry.
