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?
I'd go along with Mike - it may or may not require specific marking dependent on the standard (presumably BS EN 61439 series) - it is and has always been allowable to just put a single piece of identification that allows the relevant data on voltage, current etc to be ascertained from manufacturers data sheets - it doesn't have to be marked on the product.
If the whole thing becomes an assembly, then different requirements apply
