electric water heater wiring
okay, we are in the process of re wiring alot of our basement to update it. i am about to run all new wire to the water heater. currently it is 10-3, but there is no nuetral. the only wires comeing from it are a red, black and a ground screw. as of now the white wire in the 10-3 is cut off.
i want to replace it with 10-2, but my buddie says i cant and HAVE to use 10-3, but when i told him the white wire is not being used he just says to clip it off. so doesnt that in effect make it the EXACT same as using 10-2?
i dont understand his logic! maybe someone here can help me!
