Source of large capacitors
 

Hi

This information might help people looking for large capacitors to make
rotary phase convertors. I went to the city dump yesterday and on top
of finding a working chainsaw and picking up five pounds of copper I
found six or seven large electrolitic capacitors. There was a whole
pile of discarded air conditioners and each of the large ones had a
capacitor or two.

Electrolytic capacitors cannot be used in a phase converter. (You
probably knew
that.) Motor run capacitors are what is needed for that.

Unfortunately, most dumps don't let you take anything OUT!

Thats the best place to find them, most a/c units use a 25-45 mfd for the
compressor
and a 5mfd for the fan, the voltages for them a either 370-440 vac(counter
EMF)
i have been running one for many years with no problems.
the black plastic start caps or hard start kits need to use the relay or the
electrolytic
cap will blow. the run caps don't
