[GreenKeys] Model 15 chassis voltage?

[COURYHOUSE at aol.com]

I would like to see a  really  good  article on    safety proofing tty's 
and  making  them GFI  friendly...   I  think   we  need a white paper on this.
 
I am sure  Nick and  SMECC and Gil  and George  and  other  sites  would be 
 glad to have it posted...   it  will save  some trouble and maybe  save a 
life..   Jeff ,  George, Don  or??  do  you want to take  this  on?  or?   
does it already exist and I have not found it yet!?
 
I  think  the main offenders are the 14  the 15  and  the  28...
 
Help?  thanks!
