The amendment specified the use of new cable colours for all new fixed wiring electrical installations in the UK. As mentioned these new colours are sometimes referred to as Harmonized colours as they brought the UK more closely in line with practices in mainland Europe. In July 2012, the USB Promoters Group announced the finalization of the USB Power Delivery ( USB-PD) specification (USB PD rev. 1), an extension that specifies using certified PD aware USB cables with standard USB Type-A and Type-B connectors to deliver increased power (more than 7.5W) to devices with greater power demands. (USB-PD A and B plugs have a mechanical mark while Micro plugs have a resistor or capacitor attached to the ID pin indicating the cable capability.) USB-PD Devices can request higher currents and supply voltages from compliant hosts—up to 2A at 5V (for a power consumption of up to 10W), and optionally up to 3A or 5A at either 12V (36W or 60W) or 20V (60W or 100W). [59] In all cases, both host-to-device and device-to-host configurations are supported. [60]However, since the light switch effectively creates a “break” or “connection” on the live wire to switch the lights on or off, the blue neutral wire should have a brown sleeve or brown tape attached to signify that it is a live wire. Light switch with a brown sleeve over blue cable Inward & Outward If you have a shape and you don’t know how you want it to be glued to other shapes, you probably want an inward & outward connection point. The initial versions of the USB standard specified connectors that were easy to use and that would have acceptable life spans; revisions of the standard added smaller connectors useful for compact portable devices. Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data paths. All versions of USB specify cable properties; version 3. x cables include additional data paths. The USB standard included power supply to peripheral devices; modern versions of the standard extend the power delivery limits for battery charging and devices requiring up to 240 watts. USB has been selected as the standard charging format for many mobile phones, reducing the proliferation of proprietary chargers.

Where two colours are shown separated by a hyphen, the first colour is the primary colour, usually the base colour, with the second (and third where appropriate) applied as thin bands or stripes. Occasionally cables are manufactured with less of the primary colour showing than the secondary colour (sometimes within the same cable) but this should not lead to confusion. In the CW1308 standard the primary/secondary colours are rigidly defined, and the primary colour (shown in capitals) is always the base colour.There are several minimum allowable voltages defined at different locations within a chain of connectors, hubs, and cables between an upstream host (providing the power) and a downstream device (consuming the power). To allow for voltage drops, the voltage at the host port, hub port, and device are specified to be at least 4.75V, 4.4V, and 4.35V respectively by USB2.0 for low-power devices, [a] but must be at least 4.75V at all locations for high-power [b] devices (however, high-power devices are required to operate as a low-powered device so that they may be detected and enumerated if connected to a low-power upstream port). The USB3. x specifications require that all devices must operate down to 4.00V at the device port.

It’s worth noting that television and aerial cables share some of the same wire colours as those found in household electrical circuits. Per the base specification, any device attached to a standard downstream port (SDP) must initially be a low-power device, with high-power mode contingent on later USB configuration by the host. Charging ports, however, can immediately supply between 0.5 and 1.5A of current. The charging port must not apply current limiting below 0.5A, and must not shut down below 1.5A or before the voltage drops to 2V.

The last change in UK wire colours occurred on the 31st of March 2006 and this meant after this date any electrical cables used in new fixed installations had to feature wire colours of brown live and blue neutral.

Overview

The wire colour scheme set by the CEC (Canadian Electric Code) for AC electrical systems in Canada is very similar to the one used in the US and is as follows: For the few jobs you can do, if you would like to find ot more about staying safe when working on or around electricity, see our electrical safety project here. What Have Wire Colours Changed to? In September 2007, the Open Mobile Terminal Platform group (a forum of mobile network operators and manufacturers such as Nokia, Samsung, Motorola, Sony Ericsson, and LG) announced that its members had agreed on Micro-USB as the future common connector for mobile devices.
