Mr. Seamus O'Loughlin:

Cable fault location vans, which have units in the back of a transit van. If there is a cable fault a high-voltage pulse is injected to locate it. We had units that had been there for 20 years but there was no maintenance regime for them. We had ridiculous things. The lads had to put one unit on a pallet because they were getting shocks off it. They had to disconnect it from the ground so it was on a timber pallet.
