Abstract: An insulator assembly for use in assisting the transfer of electrical power from one side to the other of a bulkhead or panel having a hole therein. The assembly uses a basic insulator device having a body portion as well as an upstanding feedthrough portion, with the upstanding portion being of a size so as to extend through a hole in the bulkhead or panel. The upstanding member is provided with a hole therethrough in which a current-carrying member is secured. Such current-carrying member forms the support for at least one connector means on the upstanding member, and at least one connector means on the body portion, thereby facilitating connection to a current-carrying member located on each side of the bulkhead.
