Hi Doug,

You are right that test with 1mm wire does not apply if no speaker terminals.

There are 3 requirements

- protection against electric shock, clause 5, test figer shall not touch bare 
live parts.
- protection against fire - openings shall comply with fire enclosure 
requirements (e.g. less than 5mm for side openings, max 3mm for bottom openings)
- protection against foreign object - Annex P.

I hope.this helps.

Best regards
Bostjan

Hello all,

A bit of a quandary here, and it could be my own fault. I'm examining audio 
equipment that has small ventilation holes above the AC Mains Inlet.

Hastily my mind jumped to the rigid wire test (V.1.6) for stripped wire 
terminals intended for wiring speakers to audio power amps. But this particular 
unit is not a power amp and it does not have that sort of wiring terminal. My 
angst is about the mains voltage immediately behind the ventilation holes. 
Section, 5.3.2.4 says to check each wire terminal opening as well as any other 
openings within 25 mm. And I this case the 1mm x 100mm wire easily reaches 
inside.

In my original thinking, I saw this as a  potential end-user hazard and thought 
this wire probe might be a good idea to use in this case.  So, my client 
balked, and I can definitely see his point. These vent holes are not for 
speaker terminals, and also not for stripped wire by the end user. As written 
in the standard, this is not a great fit for that purpose.

So what section of the standard, if any, applies here?

Thanks! ~Doug
