Legal requirement
Singapore's WSH (General Provisions) Regulations require electrical equipment to be of good construction, free from defects and used and maintained so it is safe. On worksites, the WSH (Construction) Regulations 2007 require RCCBs on all temporary electrical installations and heavy-duty industrial plugs and sockets. Hand tools used underground or in confined spaces must run at no more than 55 volts to earth.
