Abstract
A riser assembly of rigid conduit is provided for an electrical cable which is adjustable. The riser assembly includes first and second rigid conduits having a telescoping interconnection at an elongated enlarged diameter lower end of the second conduit. This permits the upper end of the second conduit to be connected by a threaded fitting to a meter box and to have the lower end of the first conduit extend below grade to receive an electrical cable. Settling of the ground or thermal expansion is readily accommodated by the telescoping adjustment without any strain on the threaded fitting connection to the meter box.
