Abstract
A spout assembly is provided. The spout assembly includes a spout and a spout base. The spout base has a cross-sectional area that is smaller than a spout sized to enclose an electrical switching apparatus electrical coupling. That is, the spout base includes a CT support surface with a cross-sectional area that is smaller than the spout cross-sectional area. Current transformers are disposed upon the spout base CT support surface.
Claims22
