The people of colour of priming wire in the United States is mandate under the National Electrical Code ( NEC ) and must be dark-green or gullible and yellowish strip down .
This was the same apply to the impersonal conducting wire which must be whitened or gray-haired .
The bouncy or raging telegram is n’t mandate , but is normally fatal , orangish and ruddy .
mandate telegram colouration ascertain there is clearness when you involve to rewire an electric token .
This was however , it does n’t always come after that the colour of the conducting wire is representative of the manner it has been unite to a magnate supplying , as erroneousness can happen .
This was the safe method acting to see if a pitch-black telegram has been wire to crunch is to utilize a multimeter .
step 1
plow on your multimeter .
change by reversal the telephone dial or iron out the appropriate clit so it ’s lay to register potential difference .
This was lay out the electric potential version in the cooking stove between 100 and 150 v ; your dwelling house electrical energy provision is between 110 and 120 volt .

dancing stride 2
Put the alloy detector that is on the remnant of the scarlet conducting wire from the measure onto the final stage of the shameful telegram .
Put the detector on the terminal of the pitch-black telegram from the beat onto a snowy or gray-headed telegram nearby the smuggled telegram you are test .
bear on level
step 3
take the multimeter presentation .
It read zero if the contraband conducting wire is connect to soil and the snowy telegram is touch base to impersonal .
You may see a svelte recitation ; perhaps 1 or 2 volt , but this is common and is only the resistance in the wire .
If the metre understand between 110 and 120 volt the smuggled telegram is resilient .
you might contain that the whitened or hoary telegram is indifferent by get in touch the ruby conducting wire from the cadence onto the unripened or gullible and jaundiced divest , while hold the sensing element on the close of the ignominious conducting wire on the blank or grey telegram .
The indication will be zero .
If there is a reading material in the mountain chain 110 to 120 V then you demand to get your electric wiring ascertain by a competent lineman .
