	Subject - Wago the dog blackrd Info I got from the manufacturer adressing my concerns about voltage drop, hot splices, etc. Sir; Thanks for taking the time to discuss (with me) your experiences with our products. As a former 'wireman', I have to admit being rather skeptical about the use of the 773 myself. After a great deal of prompting and data to support our claims, I bit the bullet and tried the units and have to admit that I am thoroughly convinced as to their performance. Unfortunately, the 'pushwire' technology has gotten a bad name over the years, primarily due to so shortcomings in design and application. As we discussed, often times, manufacturers rely on the spring itself to conduct the current within the units (whether they're connectors or wiring devices). Due to UL / CSA regulations, in these types of designs, the spring has to be a non-ferrous material (typically brass or copper/brass). Over time the unit does show some fatigue and these types of alloys are higher in resistance to straight copper. In the WAGO unit, we employ a stainless steel spring design that surrounds the conductor and holds stranded wire 'captive' and in contact with a copper current bar. This design is unique to the WAGO product and cannot be found in the 'knock-offs' that are out on the market. For your review, I've attached three tests in PDF format - the third (773EXTest) is the testing for the application of the product into 'Hazardous Locations'. If you or your colleagues have any questions, please do not hesitate to contact me immediately - Thanks again for your time and interest! Best regards, WAGO Corp.

I should have it up tomorrow.
