▪ Visual inspection of correct condition
▪ Protective measures to prevent direct contact (basic protection)
▪ Protective measures to prevent indirect contact (fault protection)
▪ Where appropriate, protective measures providing additional protection
▪ Where appropriate, recording of the temperature of relevant electrical operating
resources.
In the case of moveable electrical operating resources, the tests must cover the following,
as a minimum:
