Rick,

Are you talking strictly about power cordage or internal hookup wire?

We had a CSA inspector reject one of our products because the internal PE 
Conductor (hookup wire) was a smaller gauge (18awg) than what was on the power 
cord (16awg). He said in Canada, the PE Conductor inside our product had to be 
the same gauge or larger than the PE conductor in the power cord regardless of 
the protection device or the current rating of the wire. In our case, we were 
using a 16 awg detachable power cord with an IEC 60320 connector. Inside our 
instrument, from the IEC connector to our chassis ground we used an 18 awg 
green/yellow hookup wire which can handle way more fault current than the 16 
awg power cord. So as a general rule, we always use 14 awg hookup wire on IEC 
connectors just to be on the safe size; As such power cords can come in 18, 16, 
and 14 awg sizes.

Our power cords for North America always have UL and CSA, but no CE or 
"harmonized" (at least it is not required to have this). When products are 
shipped to Europe I understood that UL/CSA cordage was acceptable (you still 
have to change the plug) as long as the conductor size met the requirements. 
That is why we don't use 18 awg power cords anymore.  I really don't know the 
details because this is handled by our installers during the customer 
installation.

Hope this was helpful.

Subject: [PSES] Wire Questions

We manufacture a product that is intended for both the US and Canadian markets 
in addition to the European community. Our wiring is currently UL/CSA and 
"harmonized".  Looking at the various wire vendors there are UL/CSA & CE 
certifications and certifications  that are UL/CSA, CE and Harmonized. Is it 
acceptable to have  wiring with just UL/CSA and CE?

Also, I remember years ago a document or standard that stated that a grounding 
wire could be smaller than the load wires. The argument was that it doesn't 
have to support the load but just fault  the input current.  Does this sound 
familiar to anyone?

Thanks

Rick
