Some SRESU members use T plugs for connecting radio equipment to a power source.
One problem that often arises is how to wire these T plugs for use on DC.
There is no international standard for this type of connector and debate continues between NSW WICEN and Victorian WICEN as to what is the correct way to wire them.
Within the SRESU it has been accepted that we follow the Victorian WICEN convention.
This convention suggests that the more negative wire (often called ground or earth) should be black and the more positive wire should be red.
