IEC vs. UL/NEMA

IEC vs. UL/NEMA

IEC vs. UL/NEMA

(OP)
Anyone know the difference and/or the pros and cons of uisng IEC rated equipment versus UL/NEMA rated equipment?

RE: IEC vs. UL/NEMA

That's really going to depend on the type of equipment you're talking about, and where you are located.

In the US, all equipment needs a UL label, regardless of whether it's built to IEC or NEMA standards.  

If everything else seems equal, check the physical size and weight.  

RE: IEC vs. UL/NEMA

Are you are referring to motor starters,pushbuttons, etc?

If so, here's a quick comparison and (I believe)is true for all major brands such as AB, Square D, GE, etc.:

NEMA components are more rugged, field repairable, larger, last longer, more versatile, and generally are more costly.

IEC components can do the job well, are smaller, and cheaper.  That seems to be the deciding factor anymore.

I prefer using NEMA whenever possible.
