Testing GFCI's [RE-wrenches]

[Nick Lucchese]

<x-flowed>

Hello Again,

No responses but that's okay. After another conversation with the 
customer the story changed a bit. The neutral to ground at the sub 
was removed and put back in place at the main service. I was able to 
instruct him back to my original configuration and problem solved. 
Thanks to those who may have been scratching their head to offer an 
explanation.


Have a great weekend,

Nick A Lucchese

>tools for construction) on this single 20 amp circuit from the 
>utility while he builds the house. When the inspector uses his GFCI 
>tester with the E-panel in inverter bypass mode (utility) everything 
>checks out okay and the GFCI trips. Once the utility is removed from

>wires were reversed so I got the customer to open up the E-panel to 
>trace the wires and confirm that in fact everything is wired 
>correctly. I'd really like to understand how this can happen so that
