Hi,
I work as a Maintenance Electrician and part of my Testing role is to complete Insulation resistance testing on Supply cables between Metal cabinets on Highways Equipment - Normally Armoured or similar.
I have had 2391 since 2006 and at no point in my Testing Course did i ever come across something a colleague of mine seems to be insisting we all do. That is "Conductor to Ground Testing". I have in the past completed Phase to Neutral, Neutral to Earth and Earth to Phase and recorded these on my test certificates (All supplies are single phase). As far as I know there is nowhere to record such tests on any software or sheets I have seen. Am I missing something fairly obvious or does this seem pointless to others too?
Regards Chivs
