Frigidaire washer [RE-wrenches]

[Joel Davidson]

One of my customers insisted on buying an SW5548 and a 120/240VAC transformer
because he had mostly 120VAC loads but also "a 240VAC well pump." His installer
told him that the SW5548 would not work on the pump, but installed it anyway per
the customer's instructions. The customer ended up returning the SW5548 and
getting an SW4048 and now the well pump works. A Trace employee told me that the
SW5548 does not have as much surge capability as the SW4048 because of an
undocumented voltage sag that Trace knows about.
