[citation needed] A common mnemonic electricians use to remember which wire goes to which terminal is "white to light…black to brass…green to green". [6] Phase wire in a circuit may be any color other than green, gray, or white (whether these are solid colors or stripes). The common colors are black, red, blue, brown, yellow, and orange ...
Each appliance and each room are highlighted into autonomous circuits - this apartment has 14 individual circuits. A relay is used to control the light fixtures in a large room. In new home construction, wiring for all electrical services can be installed before the walls are finished.
A wire or cable has a voltage (to neutral) rating and a maximum conductor surface temperature rating. The amount of current a cable or wire can safely carry depends on the installation conditions. The international standard wire sizes are given in the IEC 60228 standard of the International Electrotechnical Commission.
A receptacle tester being used to check for some types of improper wiring of an outlet. For this particular tester, proper wiring is indicated by the two yellow lights. The outlet tester checks that each contact in the outlet appears to be connected to the correct wire in the building's electrical wiring. It can identify several common wiring ...
The voltage and frequency of electric power differs between regions. In much of the world, a voltage (nominally) of 230 volts and frequency of 50 Hz is used. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other combinations exist, for example, 230 V at 60 Hz.
The mains frequency is 50 Hz in all these countries. Over time, Pacific Island countries that use AS/NZS standards will also transition to the newer voltage of 230 V. [ original research? The standard is used in Australia, New Zealand, Fiji , Tonga , Solomon Islands , Papua New Guinea and several other Pacific island countries.

for AC having a supply frequency of 50, 60 or 400Hz, though the use of other frequencies for special purposes is not excluded. This includes low-voltage installations, as found in most domestic and commercial properties, and extra-low-voltage systems, but excludes high voltage , as found in generation, transmission and distribution networks.
