| Is the condensation pump attached to a furnace (for air conditioning)
supposed
to be hard wired?
TIA

Not in the National Electric Code. There may be something in the
mechanical code.

thank you for the reply back! long story short I have to have an inspection
done and I thought it was supposed to be hard wired but as you know it the
other way around.

In our place, the previous owner did hard wire it. Trouble is that it was
just put across the main feed for the air handler and the emergency heat.
That's a 60 amp circuit! The wires serving the pump were like #14 or #16.
Moreover, our air handler was 240 volts (no neutral) and the previous owner
picked up "neutral" by using "ground."
If you have a separate CB that just handles the control transformer and the
blower motor you can safely hard wire the condensation pump. But if you
have a 240 volt blower motor, etc, just wire a plug to the pump and plug it
into the "convenience" outlet that should be near the air handler.
Some condensation pumps have an extra set of contacts that open when the
reservoir is about to overflow. You just wire these in series with the
compressor control so that if your pump fails (or someone pulls the plug)
you don't create a flood.
I completely understand your concerns. The "safe" way is for the pump to
be on a 15 amp circuit but to have the "overflow" contacts turn off the
compressor if the pump isn't functioning.
A typical heat pump "complex" is served by more than one breaker. If the
control transformer is in the air handler then there is no way the
compressor can operate unless the air handler is powered. Carrying this
philosophy futher you wire the overflow switch in the pump so that the
compressor will not continue to operate if the pump fails.

I got a call back last night and was informed that the device being
hardwired in *our township* is a code violation, so I'm ok.... for some
reason I thought I'd heard it was the other way around
