Beginning now, some AO Smith/Regal Beloit motor models will be shipping with updated wiring. We have begun phasing out the old "terminal board" design in favor of a simpler wire-to-wire connection one. Our intention was to phase these out towards the end of the year, however we have sold more motors than anticipated this year. Therefore, some models are already being sent out with the new wire-to-wire design. This change eliminates the need for those difficult to use spade terminals and simplifies the wiring procedure. We apologize for the abrupt change and any confusion this may create. Please see the updated wiring schematic that has been added on the Wiring Diagram page of our site.
