nuetral current
(OP)
I have a 220volt service. I put my ampprobe on the neutral and have approx. 15amps. This is a single phase system. On the other 2 phases I have 3amps to 16amps. I know they are not balanced but what is causing the current on the neutral. The neutral is bonded to ground. Thanks you for any replys. Puzzled!

Current in the neutral is normal and not a concern.
RE: nuetral current
theoretically, you should be getting 16-3=13 amps on the neutral...not 15amps..unless you have some wiring that is not properly wired...like picking up 120v from the ground instead of the neutral...i've seen this wiring esp. in residential houses or old buildings..

Re[Ineutral] + jIm[Ineutral] + Re[Ihot1] + jIm[Ihot1] + Re[Ihot2] + jIm[Ihot2] = 0 + j0, in amps
A power factor meter could help in this situation.
