Re: Carpet?

[James McKenzie <mcs () 1ipnet net>]

 If I may, don't expect your carpet installer to know how to figure the
grounding straps out.  I've known way too many of them.

 You should pre-determin where the straps are going to be and how they are
to be attached to the grounding source and amke sure that it's actually
available where the strap is.

 I could see a carpet installer doing one of the following:

        1) cut it off
        2) tuck it under
        3) nail it to the floor
        4) ignore it and maybe you can find it when he's done
        5) "I don't know what to do with this, so I'll leave it exposed for you to
deal with"
        6) "Listen, I don't know anything about 'grounding' a rug.  I'll have to
come back later.


 Nothing like carpet installers...
