the added exception to code#702.6 for mobile generators =
"Temporary connection of a portable generator without transfer equipment shall be permitted where conditions of maintenance and supervision ensures that only qualified persons service the installation and where the normal supply is physically isolated by a lockable disconnect means or by disconnection of the normal supply conductors."
I installed a kirk-key interlocked panelboard with 2 breakers (utility&generator)
The inspector said the panelboard needs to listed as a transfer switch.
I have not found any UL listing for manual transfer switches just automatic.
The interlocks are listed and the panelboard is.
Is there another NEC code that talks about key interlocks?
