When undertaking routine fixed wire testing at a client’s premises recently we were concerned to discover that all was not as it seemed with one of their trailers.
Used as a mobile asbestos removal unit, the trailer is ‘plugged in’ to the electrical supply wherever it is being used, but on inspection we discovered that this particular trailer had incorrect polarity on its supply socket. The live and neutral were connected the wrong way round on the supply socket into the trailer. The consequences of this were that the fuses would not trip and isolate correctly and nor would the RCD, thus creating the risk of electrocution in the event of a fault. All in all, a hazardous discovery, and our client was understandably very grateful that we uncovered this potentially dangerous situation.
