We strongly discourage the use of an adapter due to potential :safety h_ards..
For temporary connections, use only a UL-fisted adapter, available from most
local hardware stores. Ensure that the, large slot in the adapter is aligned with
the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid
damaging the ground terminal. Avoid frequently unplugging the p,ower cord as
this can lead to eventual ground terminal damage.
