Mains appliance disclaimer

I recently bought a mains appliance, specifically worktop power outlets with USB chargers built in. On the back the label states "This unit should NOT be subject to any insulation resistance testing", and also "THIS LABEL SHOULD BE REMOVED DURING INSTALLATION".


Is this a legitimate constraint for a mains appliance? Shouldn't any device designed for mains power be able to cope with likely power line events?

    Hi Alex,


    I agree with what you say, most Electricians will make an assessment if there is any sensitive equipment that could be damaged but unfortunately sometimes damage does still occur from a test carried out at an inappropriate voltage.
