Adapter plate for converting a three phase meter socket for use with a single phase watt hour meter

摘要

An adapter plate interposed between a single phase meter and a three phase meter outlet to benefit from the more economical operation of a single phase meter when the premises no longer requires the three phase outlet power. The adapter plate includes a sleeve having a barrier and four blades which contact four 120 volt clips operatively connected to 120 volt power at the outlet site. The adpater blades include four clips oriented to receive a single phase meter. Two of the clips are offset from two of the blades to which they are connected so that the single phase meter can be aligned with the three phase outlet socket and thereby accurately monitor power used on the premises. Three legs defining the 200 volt leg wired to the premises are effectively isolated by the adapter.
