Next week I get to work on one of the Manager's - Wife's Iron. Dry cracking, cuts etc.... Perhaps a goal of replacing the HPN wiring on a vintage iron... "was sparking." Yea! cracks to conductor etc all over its cable. Cord length was luckily short enough my cable supplier was able to just "sample" it out. How as a Manager of a lighting company, didn't you question it's wiring before it started sparking?
