PERIODIC INSPECTION AND TESTING OF DOMESTIC ELECTRICAL INSTALLATIONS
Sponsored links
This four day qualification course deals with the knowledge and practical requirements for those electrical installers who wish to be able to issue Periodic Inspection Reports for Domestic Properties only.
It does not deal with non-domestic installations or three-phase systems.
