⚡ A fault hidden in plain sight…
While carrying out a caravan service this week, routine electrical testing highlighted an open earth fault on the mains supply.
With the fault identified, the next step was to trace the cause. Investigation led back to the customer’s 13A mains adapter lead where, after dismantling the plug, the earth conductor was found to be disconnected.
From the outside, the adapter looked perfectly fine.
This is exactly why a thorough service involves much more than visual checks. Testing can uncover faults that would otherwise go unnoticed and helps ensure caravans remain safe to use.
