You are confusing common practice with Code compliance. Look at the NEC Code requirements in 200.7. Other than a few specific exceptions, white insulation is reserved for a grounded conductor. If it is in a prefab cable assembly and you permanently change the color everywhere that it is accessible and visible, then you can use it as an ungrounded conductor, as it is no longer considered a white wire. The original response by Tick Tock just talked about reconnecting the white wire to a breaker, not changing the color, which was my objection. You also seem to advocate that.
I don't "advocate" anything. =A0 I merely point out the practice.
Why? =A0 Because it doesn't present a risk to folks who know what they are doing. See my previous posting regarding homeowners.
Well, they have to learn. =A0 Maybe the hard way.
=A0=A0=A0=A0When you open a J box that has a switch, for example, you don't expect the WHITE wire to really be neutral.
Yes, you should. White wire should NOT be used as an ungrounded conductor to a switch. If there is one in the box, it should be a grounded conductor.
There is a Code allowance for using the white conductor in cables on the supply side of 3-way or 4-way switches, but that now requires coloring the insulation. In the past, this wasn't necessary. What about a 2 wire "switch loop?"
When you disconnect a cable from your 240 water heater you don't expect the white wire to be neutral. When you disconnect a cable from a 240 outlet without a neutral, you don't expect the WHITE wire to be neutral. According to the Code, you SHOULD expect that! You and I might not, based on our knowledge and what we observe, but what about an average homeowner who dabbles with his own electrical work? You can see what the level of knowledge is by the questions that routinely appear on this group from do-it-yourself electricians.
Again, they will learn!
REPLY: I never said anything against color coding the white conductor - See Here - Practicality Need Not be Hazardous No One should assume that a Skilled Electrical Craftsman would leave Anything to Chance to a Consumer that has Contracted Him to Apply His given Electrical Expertiese for the benefit of his Familiy or Households Convenience...It's just Not Good Practice - & I advocate leaving it well open to interpretation for the next guy 5 - 10 weeks or years from now...
I Never Assume anyhting with Circuits & I Always Cross The Tester on All Conductors Before servicing them ..... no mater how simplistic the measure applicable.
