Maybe an odd question, but when I was refurbishing my hallway the other day I found an old electrical cable bonded to the staircase at one end and running to the area of the meter and CU at the other. No longer attached at that end. From the look of it dated to when the house was built in 1949, with old style brown non-PVC insulation and I'm guessing was an earth cable. Everything has since been rewired at least once so it hasn't been used for a long time.
But should a steel staircase (and steel framed house) be earthed?
