in house hold wiring what is colour of earth wire
Electrical wiring In the United States, color-coding of three-phase system conductors follows a de facto standard, wherein black, red, and blue are used for three-phase 120/208-volt systems, and brown, orange, and yellow are used in 277/480-volt systems. In buildings with multiple voltage systems, the grounded conductors (neutrals) of both systems are required to be identified and made distinguishable to avoid cross-system connections. Most often, 120/208-volt systems use white insulation, while 277/480-volt systems use gray insulation, although this particular color code is not currently an explicit requirement of the NEC.[3]
Power Rangers As in Super Sentai, the color palette of each Power Rangers team changes every series.[note 3] Only Red and Blue appear in every Ranger team, while a Yellow Ranger has been present in every season except Power Rangers Dino Charge. Other colors and designations also appear throughout the series.[note 4] A Rangers' color designation also influences their wardrobe throughout the series: civilian clothing often matches Ranger color.[note 5]
