If this is professionally installed, it would never have passed if it had the wrong wire gauge. And installers don't like to put their name on the line and will insist in using the proper gauge, so it must have had the correct gauge from the beginning. Since it was a new install (replacement charger) I wonder what the reason was to replace the previous one - was it acting up? Was there a problem with the wiring (interrupted or not properly connected/tightened down)? Especially if you use a dryer outlet for the 240V source, that could have been an old outlet and if it was corroded, no lonnger able to supply much current, so that could have been one (common) cause of failure. I have had a situation where a wire had been twisted back and forth enough times to break enough strands internally that it could no longer handle the current and eventually if cleanly burned off, leaving a lot of soot and a 1/2 inch opening in the wire. No fire, luckily. And this was only 16A. (No EV, it was a washing machine with an electric heater - common in Europe)

I assume from the pictures that the charger they replaced was a wall charger not in the car. They most likely did not change to a larger gauge wire in the wall. They probably just put in a different breaker. The new charger pulled more current than the wire could handle and burned up. Be nice if they followed up with an explanation but we will probably never know. ________________________________ From: Paul Dove via EV <ev@lists.evdl.org> To: brucedp5 <bruce...@operamail.com>; Electric Vehicle Discussion List <ev@lists.evdl.org> Sent: Thursday, November 6, 2014 6:38 AM Subject: Re: [EVDL] Volt pih EVSE a suspect in NW Houston TX garage fire Bet it was his BMS Sent from my iPad > On Nov 6, 2014, at 2:43 AM, brucedp5 via EV <ev@lists.evdl.org> wrote: > > > > % ?Bad wiring, defective EVSE, wrong EVSE choice for a Volt pih? % > > http://www.khou.com/story/news/local/neighborhood/2014/11/05/electric-ca r-charger-may-be-to-blame-for-garage-fire-in-nw-houston/18531911/ > Electric car charger may be to blame for garage fire in NW Houston > KHOU Staff November 5, 2014 > > [image > http://www.gannett-cdn.com/media/KHOU/None/2014/11/05/635507852942292406 -Bayou-Vista-Garage-Fire.JPG > An electric car charger is being blamed for a late night fire on the > northwest side of town.(Photo: Metro) > ] > > HOUSTON - An electric car charger is being blamed for a late night fire on > the northwest side of town. > > According to the Houston Fire Department, it happened around 11:45 p.m. on > Tuesday at a home in the 5000 block of Bayou Vista near Bolivia. > > Luckily, the flames stayed in the garage but completely destroyed the > family's Chevy Volt.
