Three phase electric motor terminal box mounted connection board

摘要

A three phase, dual voltage electric motor connection board is provided with pluralities of electric terminals that project from opposite exterior and interior surfaces of the connection board, where only those electric terminals projecting from the connection board exterior surface are accessible by the end user of the motor. Only those motor lead wires that are changed when connecting between a low voltage application and a high voltage application of the motor are connected to the electric terminals on the connection board exterior surface. The remaining motor lead wires are connected to the electric terminals on the connection board interior surface. Electric terminals for connection with separate power supply wires are also provided on the connection board exterior surface.
