[RE-wrenches] SQ Flex question re Code compliance

[R. Walters]

One thing I always point out when it comes to "Code compliance"  
issues is that we are required to install the equipment per  
manufacturer's directions. I've had great luck with AHJs, by just  
copying sections of the manual and show them we're doing it the way  
it shows. One problem I see, is that the SQF is only CE listed 
( European Union), not UL or ETL, though.

Good Luck,
