Re: FYI: Home Depot Good buy on conns/cables 20' 3Phase

Drew,
Those are the 2 documents I'm going off of also.

Thats an interesting point on the motor switch.
If the 3rd 'derived' phase is disconnected, the
potential relay (normally closed) should be closed
automatically(connecting the start cap) until the the 3rd leg is
reconnected and up to speed/potential. Are you sure you dont have
the common coil/contact swapped somehow? In the diagram for the
rotary convertor it is reversed from that of the static, since a
'slave' contactor is being used. Also, where are you referencing
the other side of the coil for neutral? I went with the dual-primary
tranformer centertap. Then I can have an aux low voltage supply
for an RPM meter and monitor etc.

Let me know what you find,

-Lee
