Yes, the DC Spark Test is applicable to single conductor cables and assemblies of insulated single conductor cables that do not have an insulation shield, metallic sheath, or metalic armor. This test helps to ensure that the cable insulation meets the required dielectric strength and will be able to withstand the electrical stresses it will encounter during use.

How can we determine or find out the proper size of any cable if nothing is mentioned on it.Calculation of size in Sq.mm???
