It has been customary to run wiresfrom a plating dynamo any old way and grounding has fre-quently caused trouble which thes-3 fixtures will prevent. THE POLISHING AXE PLATING OF METALS. 173 Insurance companies are getting more strict and many ofthem now require that any bare wire carrying electricityshall he suitably insulated. These insulators will complywith such demands. As to the sizes of the tap wires needed to carry currentfrom the main conductor rods, little is really known, exceptthat they are generally too small. The man who sells andinstalls a dynamo will get his main leads big enough if theplater will let him. But the poor connections, the lack ofmeasuring instruments, and the absence of reliable dataas to the amount of curre
