I have two new isolators in enclosures bought from a nationwide wholesaler. The isolators are not marked as to manufacturer or for nominal current. Apart from the statement on the cardboard box, their are no other markings. The installing contractor tells me that the only difference between the 32A and the 63A is the colour of the plastic on the spindle. Does anyone know if this is an acceptable means for a manufacturer to identify the nominal current rating of their product?
As far as I am concerned it is not acceptable for components not to be clearly marked with their rating and manufacturing standard. When doing EICRs I am faced with isolators that have no standard or rating visible without dismantling the board to see what may be written on the side. Or should I just guess and accept that if they have not failed so far they are probably OK? Of course there is often no isolation available for the isolator!
I cannot quote a product standard that says they should be labeled although I am sure there is one. Hopefully someone on here will know.
