It could have been multiple runs for different. Never saw it in a water heater, but I ddid see it for an electric furnance in a module home. Multiple runs of 6-3 with multiple circuit breakers. I would say 12-4 with ground in other than rubber cord would be a special order around here.

Strange the water heater needed a 10-3. I haven't seen one that uses 120 v, so it should have only needed a 10-2. But hey, lots of stuff changes so fast it is hard to keep up with it. I guess it is possible that the water heater needed 2 240 v lines, one for each heating element, that would explain the 4 colors, white, red, blue, and black. But the only color safe is green, according to wiring code, green color, or bare wire is always to be the ground, green can not be used for anything else, well and white, it is to always be neutral, that is why when it is made hot, it is to be marked black. Of course, if you didn't do the wiring, you don't know if the person before did what they are supposed to Michael _____ From: [email protected] [mailto:[email protected]] On Behalf Of Lenny McHugh Sent: Thursday, April 30, 2009 10:14 PM To: [email protected] Subject: Re: [BlindHandyMan] electrical color and orientation No, first the sears water heater was wired with white,red, blue, and black when I took the line from the breaker it was a 10/3 white, red and black no one could tell me how to hook it up. even the sears manual or support could not tell me. I had to get an electrician in to figure it out and hook it up. Years later when weremodeled the bathroom the electrician used 12/4 with ground, which had the blue wire. ----- Original Message ----- From: "Bob Kennedy" <bobke...@bellsouth. <mailto:bobken54%40bellsouth.net> net> To: <blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com> Sent: Thursday, April 30, 2009 9:24 PM Subject: Re: [BlindHandyMan] electrical color and orientation I'm betting the blue was actually green in which case that would be the wire for a 3 way switch.

Before I switched to gas hot water the old electric unit had white, red, black, blue and ground. About ten years ago I had an electrician run some gfci lines in the bathroom. at one point he used a a 12/4 with ground. This 12/4 had the white,red,black and blue wires. I don't remember if he used the blue for the hot that was gfci protected or the blue for the hot that was not gfci. ----- Original Message ----- From: "Michael Baldwin" <mbald...@cableone. <mailto:mbaldwin%40cableone.net> net> To: <blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com> Sent: Wednesday, April 29, 2009 10:32 AM Subject: RE: [BlindHandyMan] electrical color and orientation In AC, normally it is the black that is hot, when your talking about 120 v, with 240 v, it is normally the black and red, if it is three wire, or both black and white are hot if it is just 2 wire 240 v. When the white is made hot, it is suppose to be marked with a piece of black electrical tape. use to be able to use a black marker but that can ware off over time. _____ Michael From: blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com [mailto:blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com] On Behalf Of Spiro Sent: Wednesday, April 29, 2009 8:36 AM To: blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com Subject: [BlindHandyMan] electrical color and orientation Ron, Tom, bob, Dale: I guess my mind is going.
