Terminals and Components

Typical single-phase dual capacitor motors have 6 terminals or leads, often labeled as follows (may vary by manufacturer):

T1, T2: Main winding terminals

T3, T4: Start winding terminals (connected through capacitors)

T5, T6: Capacitor connections or additional winding leads



2. Connection Scheme (Conceptual)

Component

Forward Wiring

Reverse Wiring

Main Winding

Connected directly (fixed)

Same as forward

Start Winding

Connected through capacitors (normal)

Capacitor connections swapped

Capacitors

Connected in series with start winding

Polarity of capacitor leads reversed

Switch

DPDT or drum switch that swaps start winding leads connections

See forward

3. Example Simplified Wiring Steps

Identify the main winding terminals (T1 and T2), connect them directly to power (line and neutral).

Identify the start winding terminals (T3 and T4) connected via capacitors.

Connect a DPDT switch between the start winding and capacitor leads, allowing swapping of start winding leads.

In the forward switch position, connect start winding leads to capacitors in one phase.

In the reverse switch position, swap the capacitor connections to the start winding, reversing phase and motor rotation.

Ensure power is off while wiring and secure all connections appropriately.

Important Notes and Safety

Always consult the motor nameplate and manufacturer wiring diagram as terminal labels and wiring may vary.

Using a proper rated reversing switch (DPDT / drum switch) is critical to handle motor currents safely.

Thermal overload protection and proper grounding must be ensured.

Never change connections while motor is powered to avoid damage or shock risk.

If in doubt, consult a qualified electrician or technician.
