New Red Black Electrical Wiring Images - That smoky scent become your fan manage failing -- fan controls and dimmers commonly are brief-circuits when they fail, so it's why the fan ran at full pace when you attempted the fan control the second time. The uk recently (2004) modified its machine to comply with that of the worldwide electrotechnical fee (iec). Despite the fact that its ground cord shade (green with a yellow stripe) remained the equal, the coloration for neutral wires, which formerly was black, need to now be blue. Likewise, where an antique unmarried-section line was crimson, now it have to be brown.
