Hot is any line or neutral conductor (wire or otherwise) connected with an electrical system that has electric potential relative to electrical ground or line to neutral. Ground is a safety conductor with a low impedance path to earth. It is often called the "ground wire," or safety ground. It is either bare or has green insulation. [1]
A newer stage pin connector. Note the GR denoting the longer ground pin, which is slightly off-center to prevent the plug being inserted upside down.. A stage pin connector, also known as a grounded stage pin (GSP), grounded pin connector (GPC) or theater paddle (TP), is a standard cable type for theatrical lighting in North America and in many countries in the theatre world.
Per UL Standard ANSI/UL 498, a receptacle (any color) with an orange triangle, is an isolated ground (IG) device, where the grounding pin of the receptacle is connected to ground independently of the frame of the receptacle and wiring outlet box. This is also a requirement of the National Electrical Code (NFPA 70), Article 406.
The pilot pin is located in the centre of main contact circle on 4- and 5-pin connectors. On 3-pin (2P+E) connectors, it is located on the contact circle opposite the ground pin. The other connectors are located 105° on either side of the earth pin, rather than 120° as in the smaller variants, to make room for the pilot pin.
A ground connection that is missing or of inadequate capacity may not provide the protective functions as intended during a fault in the connected equipment. Extra connections between ground and circuit neutral may result in circulating current in the ground path, stray current introduced in the earth or in a structure, and stray voltage.
1×6 pin header (one row) 1×6 female header (one row) A pin header (or simply, header) is a form of electrical connector. A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings. [1] Male pin headers are cost-effective due to their simplicity.

The most common of these was the three-pin XLR connector (also called cannon jack in some countries). When DMX512 was ratified, many of these manufacturers then issued firmware updates to enable the use of DMX512 control on their existing equipment by the use of a simple adapter to and from the standard 5-pin XLR style connector.
