In an office environment...
So please tell me I'm a dunce on this one (I'll gladly wear a hat with a 'D' on it) but one thing I've never really got with PA Testing is when testing Class 2 equipment part of the test is one where you need to use the fly lead to clamp to some exposed metal part of the unit.
Now correct me if I'm wrong but if a Class 2 equipment unit does not have any exposed metal then where does one put it for the test?
I have been using a heavy-duty paper clip clamped to the lead clamp and held it against a deep-routed screw in the casing as it's the only way to reach some metal part - although that in itself is not right as the screw is usually screwed into plastic.
Similar goes for any power adapter for any piece of equipment that does not have any exposed metal part...
Also - as it's that time of year again - if a string of Christmas lights are of the old style type (in series where if one bulb out then the whole lot are out) and it's wired to a plug using only the Live and Neutral as no Earth wire - there is a label on with CE mark and Double Insulation mark. Bulbs indicate 12v 1.1w.
...so I'm of the opinion that a visual check is the only requirement. Also I'll be ensuring they plug them into an RCD socket.
Am I right this?
