Had to go to Discover Darlington this morning, just outside the service bays was a burnt out wreck that yesterday was someone's pride and joy until an as yet, unknown electrical fault started a fire in the caravan which was still hitched as the owner was at the service reception. One of the Discover employees spotted the fire starting and ran over and dragged both gas cylinders out then unhitched the car. We were told the fire only took 5 mins to totally destroy the caravan, I took a pic on my phone, there's only the chassis left, but don't know how to upload them. 2 of the Discover stock were slightly damaged but it could have been much worse.The after sales manager said a PIR check would have prevented it maybe.
The After Sales Manager appeared to be making a "Get out of Jail!" statement.
Like RodderStrotter says I thought a PIR Test is for mains electricity and the caravan wasn't connected to the mains.
Im not so sure, I would cover 12V if I was doing a PIR, at least a visual inspection, cant find my inspection and testing book right now, but I do know the the 12V system is included in the BS7671 wiring regs (was reading that bit last night).
Any sparks with the testing book to hand??
