Home electrical ?

Does anybody know if there is a dedicated "colour code" of wiring that is used for a dishwasher?
Mine happens to be black from breaker panel to the DW. But, I have someone telling me, that line should be yellow. News to me, any truth to this?

[Steve Wood]

never saw one like that...normall y, they are black, white, plus a bare wire or green for the grounding wire.  Of course, that is for the U.S.

I know of no use of yellow wiring in standard home wiring. Maybe yellow ROMEX, but not individual wires.

Not sure where the yellow came in unless you have a industrial unit.

It is an isolated unit; maybe you have a local code? Check with the corporate office.

Just re-did ours a year ago; standard hard wired to the unit according to the current consumption. No local code here, just had to comply with Code C22.1 which was a non issue.

That would make sense 12 guage wire, heavy washing machine, or because the run length. Or a local code.

Well that's what I thought. This guy is a bit of a mouth piece and I wasn't sure. So I just avoided an argument and find out on my own

Type NM-B cable first began to be manufactured with color-coded jackets in 2001 to aid in identification of the conductor size. The color code that was introduced, which continues to be used today is as follows:

14 AWG – White
12 AWG – Yellow
10 AWG – Orange
8 AWG – Black
6 AWG – Black

This color coding system was developed to aid those who sell, install, and inspect Type NM-B cable so that the cable size can easily be identified, to reduce mistakes resulting from the use of an incorrect conductor size.

It should be noted that this color coding system is not a requirement of NFPA 70, National Electrical Code® (NEC®) or UL 719, Safety Standard for Nonmetallic-Sheathed Cable. Type NM-B can be produced and sold without using this color code. As such, the print legend, which is required by the NEC®, should be used to verify the conductor size.

Ontario also has blue 14/2 romex which is to be used for arc fault protected circuits in bedrooms

Dave, so if using #12 (not needed for DW) wire then yes colour code can be used, but not law correct?

[daveismissing]

I read it to mean the colour is a convenience but as long as the gauge and insulation specs are OK per NEC/CEC
the the wire is legal.

I can see how 'assumptive' people would think its a hard and fast relationship.

Thanks alot

Black sounds like it might be "wet" wire - thick insulation?

We forgot red romex for 220v ccts
