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.
Sounds like it is missing a label or two. Certainly anything electrical that would normally be CE marked like a light fitting has to have a rating, but that may be allowed on the packing or the handbook, but the device must still have enough identification to allow it to be identified and the data traced, even if only a makers logo and a part no on a paper label. Similar requirements have been in all sorts of product standards since many decades.
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

So Who makes it ?
As an aside, the lighting industry association require such information to be placed on the fitting itself, just being on the box or instruction sheet is unacceptable. Trading standards in my area were keen to investigate when I told them about a fitting from a shop that had no such info on it, they went to the shop the following day.

Hi Lyle, presumably you are possibly referring to a rotary type isolator due to the reference to 32/63A rather than a dinrail type switch in an enclosure?
The details are usually on a sticker inside the enclosure, as the stickers may get jet-washed off if they were on the outside :)
Hi Lyle, a brief description of what you saw would be helpful rather than waiting until Tuesday for a pic, what type of electrical equipment are you referring to, an accessory or switchgear?
