[modeleng] Re: NVR connections

The NVR will need connections to both live and neutral somewhere along
the line, the NVR is a self-energising relay with a button for starting
it manually after all....

Subject: [modeleng] NVR connections

Hello all you sons of Faraday


I wish to wire a 1ph 220vac 3/4hp induction motor (ex Myford lathe, I
believe) through a NVR
starter (Square D brand).  The motor and switch came as a 'package'.
Needless to say, there are
no instructions with the switch.

I believe that only the Live wire from the mains goes into the contactor
block and the Neutral
goes straight to the motor.  However, when I try this the contactor does
not hold in.

There are a couple of other (unmarked) push-the-wire-in-the-hole type
terminals, which I think
might be used to energise the coils of the contactor.  If this
assumption is correct, are they
both wired into the Live output terminal or where?


All help greatfully received.

Dave - who is trying to come to terms with this new-fangled electricity
stuff.
