In 240-volt applications not requiring a neutral conductor, the white wire may be used as the second hot conductor, but must be recolored with tape or by some other method. [ citation needed ] Four-wire flexible equipment connection cords have red as the fourth color; unlike older European practices, color-coding in flexible cords is the same ...
A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
A mnemonic which includes color name(s) generally reduces the chances of confusing black and brown. Some mnemonics that are easy to remember: B ig B oys R ace O ur Y oung G irls B ut V iolet G enerally W ins.
For instance, instead of 14 AWG (American wire gauge) copper wire, aluminium wiring would need to be 12 AWG on a typical 15 ampere lighting circuit, though local building codes vary. Solid aluminium conductors were originally made in the 1960s from a utility-grade aluminium alloy that had undesirable properties for a building wire, and were ...
The yellow P+N+E, 4h (120°) plug is a single phase connector that is in widespread use on the British Isles for 110 V building site and fairground applications. A popular model of this socket type is marketed under the brand name MK Commando [ 12 ] which leads some users to refer to all IEC 60309 sockets by the generic trademark Commando sockets .
The color of a device neither identifies its voltage class nor power system. Because the colors are not specified by NEMA standards, the purpose of color-coding a receptacle may be set by the building owner, who may select brown, ivory, white, almond, grey, or black receptacles in the 5-15 configuration to blend with the decor of a room.
