How To Identify Commando Plugs & Sockets

This page will help you identify exactly what plug or socket you need. Whether Single or Three Phase? 3, 4 or 5 pin? What Amperage and Voltage? Here we try to help answer questions in our easy-to-follow Plug & Socket Identification page. Covering all types:

Plugs and Sockets Explained

1. Plug or Socket

Connections are made with the plug, also known as an inlet which is placed into a matching socket, or outlet. A right connection allows the correct and stable transfer or electricity from one to another.

2. Colour of Plug / Socket

Plugs and sockets are colour coded according to volts.

3. Pin / Hole Quantity

The amount of pins indicates the voltage and amount of phases. 3 pin Blue connector is for a single phase, with one live pin, one neutral and an earth.

The 4 pin red connector contains three live pins for the 3 phases and one earth pin. Sometimes their is a pilot to ensure pins are guided correctly to one another. It is not included within the pin count.

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.

Use the following table to match plugs and sockets accordingly.

3 Pin	Plug	Socket
16A	43mm	35mm
32A	57mm	46mm
63A	69mm	59mm
125A	80mm	70mm
4 Pin
16A	49mm	40mm
32A	57mm	46mm
63A	69mm	59mm
125A	80mm	70mm
5 Pin
16A	56mm	45mm
32A	63mm	52mm
63A	69mm	59mm
125A	80mm	70mm

The International Electrical Commission govern the rules for the approval of electrical equipment, they are known as ‘CEE'

The IEC (International Electrotechnical Commission) is the organisation responsible for the international standards of electrical equipment.

‘CEE’ industrial plugs and sockets are electrical components that comply with international standards IEC 60309-1 and IEC 60309-2, also known as EN 60309 part 1 and EN 60309 part 2.
