I was working at a Best Buy here in Chandler, AZ, and was told to pull in the homerun wire to feed a Water Heater and an outlet only.
The building has 3-phase power. Circuit 24 is for the outlet and Circuit 25 is for the 120V Water Heater.
How many neutrals would you pull for circuit 24 & 25?
They are both 20-amp circuits and the water heater is rated at 1.7 KW.
The homerun wire is approximatly 150' away and I pulled #10 stranded copper thhn copper wire.
I pulled one neutral because circuit 24 is C-phase and Circuit 25 is A-phase.
I was told that I did it wrong. I should have pulled in two neutrals. Only consecutive groups can share neutrals. For Example: 2,4,6 ; 8,10,12 ; 1,3,5 ; 5,7,9
I stood up for my work and refused to aknowlege that I did something wrong.
