Went to see a customer. They have the kind of lights that supplied by transformer. The live and neutral wires are pulled across the room and the light fittings connected with screws to the wires (the screws make the contact with the wires going through the insulation).
this system has a repeated problem that is a spark between the connections of the light fitting and the wires as well as between the connections of the wires coming from the transformer and the wires that the lights hanging from. This is an existing installation, as the wires are damaged (burnt) in several places I decided to change the wires (the customer does not wish to install a different type of lighting).
I assume that the spark caused by a gap created between the connection screw and the wires.
As I would not like to change the wires and have the same problem, does some one have ideas how to eliminate or at least minimize this problem?
