A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.
Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

The voltage over the load is a phase voltage. Say you have 3 equal loads in a delta configuration. The voltage over the load is a line voltage, or vas it a phase voltage? Say yoy have 3 equal loads A in a star configuration with a N condutor in a TN network AND you also have 3 equal loads B in a delta configuration.
Three Phase Equations & Heater Wiring Diagrams Open Delta & Wye Three phase heating circuits are most effi cient when operated under balanced conditions. If it is necessary to operate an unbalanced load, the equations below can be used to calculate the circuit values for open three phase Delta or Wye circuits. The terms used in the equations

Ed, this is an unfair down vote and incorrect. In a delta system, the phase to phase voltage is the same. The B phase, or high leg only becomes a problem when you are wiring a 120V load to a panel box with a 120 240 three phase high leg delta service. The voltage across the neutral and the high leg will be 208V.

In a delta connected ( Dd ) group of transformers, the line voltage, V L is equal to the supply voltage, V L = V S.But the current in each phase winding is given as: 1 √ 3 × I L of the line current, where I L is the line current. One disadvantage of delta connected three phase transformers is that each transformer must be wound for the full line voltage, (in our example above 100V) and for ...
