I do some business online with Grainger.com. Been happy for the most part so far. Kind of off the thread's subject, but I am having trouble locating an IEC reversing contactor. It's a Telemecanique LC2K0910 120V coil with NO aux. contacts. I need one really badly right now and am going to need about 60 more over the next few months. Grainger can't get one. I found the part number listed at Telemecanique's website but can't find a vendor. Anybody got a suggestion? Sorry to stray from the subject.
Telemecanique and Square D are both owned by Schneider Electric (was Groupe Schneider). In the U.S. all Telemecanique control products are marketed by Square D and in Canada it is Scneider Electric. In both cases all items are available through all Square D distributors. Or try http://www.squared.com
I order 90% online (between three suppliers), and in the process go after manufacturers tech sheets or installation documents as needed. Ready access to the installation documents alone is worth the price of admission for me, as the docs make the design-build conundrums disolve away.
