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.

Electrical Wiring for a Workshop. I would highly encourage you to consider installing a sub panel in the new workshop that will have enough amperage capacity for your planned electrical circuit loads, and any possible future equipment that may be added. Once the workshop calculated loads have been established the size of the sub panel may be known.
An electrical panel is basically a service box that connects a main power line to a home, and distributes electrical currents to the various circuits within the home. Circuit breakers and fuses ensures there are no over currents during the distribution of power to different circuits.
A distribution board (also known as panelboard, breaker panel, or electric panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.Normally, a main switch, and in recent boards, one or more residual current devices (RCDs) or residual current ...
It may even be green. This screw is used to bond the neutral coming in the main panel to the case "panel" itself. however, in a sub panel, the neutral bus bar must be totally isolated from the ground. The very first thing the electrical inspector is going to look for is if the sub panel is bonded or not. Now as far as wiring the panel.
Terminology. Although much of the electrician's field terminology matches that of the electrical codes, usages can vary: . Neutral wire is the return conductor of a circuit; in building wiring systems, the neutral wire is connected to earth ground at only one point. North American standards state that the neutral is neither switched nor fused except in very narrowly defined circumstances.
Outdoor box: This box is similar in function to the preceding types of electrical boxes; however, it is waterproof. It often includes hinged covers that protect it when not in use. Junction box: This electrical box protects wires that do not connect to an outlet or other fixtures but rather to other wires.
How much upgrading an electrical panel should cost. Average costs and comments from CostHelper's team of professional journalists and community of users. Typically it costs $800 $1,200 to have a qualified electrician upgrade an existing panel to 100 amps, or $1,500 $2,500 if a new panel is needed.
The heart of a home's electrical system is the main circuit breaker box, also known as the main service panel. This is where the power feed from the utility company first enters the home from the meter and the point at which all the power is distributed to the various branch circuits of the house. All homes have a main service panel.

What is Distribution Board? Distribution board is a safe system designed for house or building that included protective devices, isolator switches, circuit breaker and fuses to connect safely the cables and wires to the sub circuits and final sub circuits including their associated Live (Phase) Neutral and Earth conductors. Distribution board is also known as "Fuse Board", "Panel Board ...
