Touching the service neutral

Yes, I was talking about where the neutral comes in from the POCO and attaches to the lug in the main panelboard.
When there is a load on a circuit, the current travels on the hot and neutral conductors. A single light bulb is a series circuit, that is, the light bulb is in series with the hot and neutral. The voltage drop is 100%. The potential on one side is 120 V. On the other side, it is 0 V. If you open the neutral, the load stops working, and there is no voltage drop. The neutral from the dead light bulb is now at 120 V. If you get between the neutral from the bulb and the neutral from the circuit, you are now part of the circuit, so you and the bulb will share an amount of current proportional to the applied voltage and inversely proportional to the combined resistance of both you and the bulb.

VOLTAGE DROPS ONLY WHEN CURRENT FLOWS. No current flow, no voltage drop. No voltage drop means the potential exists for current to flow through anything that completes the path.
