[RE-wrenches] Target fire

[Nick Soleil]

Hi Daryl:  
    Unfortunately, the fault would not have been found with a megger because the 
fault occurred after thermal expansion had causes the conduit to separate.  The 
fault probably occurred shortly after the conduits separated.  It appears that 
what would have prevented the incident would have been if the expansion fitting 
on the conduit had been installed correctly, with all of the conduit straps 
allowing some movement.  Also, it sounded (from the report) like the conduit 
fittings were not tightened fully (only hand tight), which contributed to the 
fault.

     This is not typical of the quality I would have expected from this 
manufacturer/ commercial installer.  Nick Soleil

I keep thinking had the installer routinely megohmed the ground and the "hot" 
they would have known a ground fault existed, and would have repaired.  The 
event would have not happened.  Then the short on the conduit would have triped 
the ground fault detector, and lead to a repair.  No fire.  

 
Again it is installers with knowledge, tools  and skills.
