How to work out what sort of Commando plug or socket you have

This page will help you identify exactly what plug you have. Is it single or 3 phase? Is it 4 or 5 pin? Is it 32 amp or 63 amp?

All of your questions are answered in our simple easy to follow page. Covering all types:
 

2. Colour of Plug / Socket

Plugs and sockets are colour coded according to volts.

Yellow - 110 Volts (100 - 130 Volts | 50 + 60Hz)
Earth position normally 4h

Blue 230 Volts | Single Phase (200 - 250 Volts | 50 + 60Hz)
Earth position normally 6h & 9h

Red 400 Volts | Three Phase (380 - 440 Volts | 50 + 60Hz)
Earth position normally 6h & 9h

3. Pin / Hole Quantity

The plug pin quantity also indicates the colour/volts. 3 pin Blue plug for a single phase with neutral and earth. The 4 pin Red for a 3 phase with earth and the 5 pin Red with a 3 phase, neutral and earth.

4. Earth Pin Position (O' Clock)

The Earth position is the largest pin and its position is indicated by the hands of a clock. As illustrated here if the earth is directly at the bottom, it is in the 6 O' Clock position (6h).

5. Diameter of Plug / Socket

To ensure the correct fit between plug and socket, a simple measurement can be taken on the outer diameter of the plug and the out diameter of the inner socket section.
