Some of Capacitor and Motor Wiring factors include:
1. Motor voltage rating
2. Motor amperage rating
3. Motor horsepower rating
4. Motor rotation direction
5. Motor casing usage
6. Mounting brackets
7. Motor run capacitor rating (MFD rating)
8. Capacitor MFD rating
9. Capacitor voltage rating
Additionally, some motors have more than one speed and will need to be wired
properly to achieve the proper speed for the control settings. An example of this
is a multispeed motor in an HVAC application will typically be wired to run slower
for heating and faster for cooling. There are important reasons for this that can
affect the comfort produced by the appliance. It may also affect the efficiency of
the appliance, so it is important to get it right. My first rule of thumb when
replacing any part is to try and get an exact replacement part. With motors and
capacitors, this is not always possible. In that case, you need to match it as
closely as possible to the existing part to make sure it works properly and as
designed.

You will also want to make sure you use proper wiring methods and make good
tight connections. To do this you need the proper tools, wire, and wiring
accessories. This includes connectors that will connect wire to wire and wire to a
terminal. Female terminal connectors may be necessary to make a proper
connection to the capacitor from the motor. It is important to make a proper
connection from the wire to the connector and a tight connection from the
connector to the capacitor. Failure to make a good connection can result in a
failed connection and that could cause the motor to burn up.
