Most likely in the neutral connection some where, either the connection at your box, in the cable, or at the utility's transformer. Note: Your panel neutral bus should be "grounded" to 0 Volts by a connection to your ground rods. This connection should be made at one location only, at the first disconnect point of your service. Typically there is a jumper between the panelboard's neutral bus (white wires) and the ground bus (green wires) in the panel, and the ground bus is connected to a ground rod in earth.
