A relatively new CSA standard (1999) has been developed from the IEC standards for LV switchgear and control gear - part 1 general rules! before i purchase the standard i would like to know how this interacts with CSA 22.2 No. 31 for switchgear assemblies? and what changes have been made?
There are another set of E catagory CSA standards for electrical equipment in hazourdous areas and the CSA people tell me the technical content has not changed - though they have not returned my call on the latter!
I tried to get a direct answer from them with respect to there intentions of introducing standardised standards and when they will be introduced. i.e. could i buy IEC rated swithchgear that will be in line with CSA standards at the point of commissioning.
anyone familiar with this?
